787EDBB51AC054B4B48D533E58CD5089.taxon	diagnosis	Diagnosis. Male: The male is the most straightforward sex to determine the subgenus but the eighth sternum and the genitalia must be extracted to ensure correct identifications. The revised diagnosis, based on a revision of Brooks’ (1988) characters, is: species restricted to south-east or eastern Asia, mainly distributed in the Indo-Malayan region (no species of this subgenus are found in Australia). The subgenus Glossamegilla can be distinguished from the subgenus Micramegilla Brooks, 1988 by (i) the long galea which reaches at least the middle of the midcoxa when resting, the galea is ≥ 3 × as long as the foretibia when measured from the apex to the maxillary palpus (Micramegilla have a moderately long galea which reach at most the anterior edge of the midcoxa when resting; the galea, with the same measurement method, is ≤ 2.5 × as long as the foretibia) and (ii) the S 8 that is apicomedially emarginate between a pair of large obtuse lobes (while Micramegilla have a S 8 apicomedially relatively narrowly emarginate between a pair of small obtuse lobes or with only a single median lobe). The subgenera Glossamegilla and Micramegilla also have different geographical distribution with Glossamegilla containing mainly Indo-Malayan species and Micramegilla containing mainly Palaearctic and Afrotropical species. These two subgenera only overlap in India, where the three Indian Glossamegilla have at least a length of 13 mm and entirely black haired terga or at least the anterior 1 / 2 orange haired but the Indian Micramegilla species have a length of ≤ 12 mm and terga with pale hair bands apically. Glossamegilla can be differentiated from the subgenera Amegilla Friese, 1897 sensu stricto, Notomegilla Brooks, 1988, Asaropoda Cockerell, 1926, Zonamegilla Popov, 1950, Dizonamegilla Brooks, 1988, and Zebramegilla Brook, 1988 by a generally wide apex of S 8, that is also emarginate and bilobed with two blunt lobes, leading to a generally rectangular-shaped sternum in dorsal or ventral view (Fig. 6 H) (while the other subgenera cited have a narrower apex of S 8, that is either bilobed or rounded, leading to a triangle-shaped sternum in dorsal or ventral view). Glossamegilla can be differentiated from Ackmonopsis Brooks, 1988, Aframegilla Popov, 1950 and Megamegilla Brooks, 1988 by the absent gonostyli (Figs 6 G, 9 G, 10 H, 11 G) (while the three other subgenera have gonostyli that are various in size and shape but always present). Usually, the long galea is a good character to determine the subgenus Glossamegilla, as the galea is ≥ 3 × as long as the foretibia (reaching to at least the middle of the midcoxa when resting), and this can help a lot for the determination as no other subgenera (especially in the Indo-Malayan region) have such a long galea. Female: There is a lack of strong morphological diagnostic characters in the females, and the main characters used are based on colouration, which varies strongly. Michener (2007) described the subgenera of Amegilla as “ largely indistinguishable in females, and in males differ from one another considerably less than do most subgenera of Anthophora ”. He however stated that the high species richness of the genus would support the recognition of subgenera, and that names were available for use by workers. A complete morphologic and genetic revision of Amegilla subgenera should therefore be made in order to validate the concepts used by Brooks and find stronger characters to diagnose them. The revised diagnosis, based on a revision of Brooks’ (1988) characters, is: Firstly, some species of the subgenus Glossamegilla have metallic hairs of various colours on the metasoma (e. g., A. hanitschi (Meade-Waldo, 1914) with the terga entirely and evenly covered by green metallic hairs), these species can be differentiated from the subgenera Aframegilla (partim), Notomegilla, and Zonamegilla (partim) by a long galea that reaches at least to the middle of the hind coxa when resting, the galea is ~ 3 × as long as the foretibia when measured from the apex to the maxillary palpus (while the three other subgenera have a short to moderate galea that reach at most the anterior edge of the hind coxa and is ≤ 2.5 × as long as the foretibia with the same type of measurement), the absence of paraocular marks (while these marks are present in the three other subgenera) as well as the biogeography (indeed, the Glossamegilla with metallic hairs like A. hanitschi are an Indo-Malayan group while Aframegilla is an African group, Notomegilla is an Australian group and Zonamegilla is a more widespread group distributed in the Indo-Malayan and Australian regions). The second group of Glossamegilla does not have any metallic hairs on the terga. The latter either show pale hair bands that contrast black hairs on the tergal discs, are entirely covered by pale pubescence, or show another type of black and pale hairs mixing (Figs 5 F, 7 F, 8 F, 9 F, 10 F, 11 F, 12 D, 13 D, 14 E, F, 17 F, 18 F, 19 F, 20 F, 21 F, 22 F, 23 F, 24 F). The pale hairs can vary from white (e. g., A. sumatrana and A. jacobi (Lieftinck, 1944) (Figs 21 F, 24 F )) to bright orange (e. g., A. feronia, Fig. 20 F). In this group, the paraocular marks can be either absent or present but the maxillary palpi always have six segments. If pale paraocular marks are absent, Glossamegilla can be distinguished from Asaropoda by the biogeography (Glossamegilla have an Indo-Malayan distribution, mainly in the Indo-Malayan region while (Asaropoda) is restricted to Australia) and the pale clypeal marks that are an inverted T-shape or the clypeus can also be entirely to almost entirely black for Glossamegilla (Figs 7 C, 12 C, 13 C) (while Asaropoda have a clypeus almost entirely pale, except for the small dark mark at the anterior tentorial pits). Glossamegilla can be differentiated from Ackmonopsis (partim), Micramegilla (partim) and Amegilla sensu stricto (partim) by the absence of hair bands on the apical margin of some terga and / or with some or all terga covered by dense and appressed pubescence (Figs 12 D, 13 D, 17 F for example) (while the three other subgenera have all the terga with a hair band on the apical margin, these hair bands can be white to ochraceous). Glossamegilla can be differentiated from Megamegilla and Ackmonopsis by the pubescence of the mesosoma that can be ochraceous, fulvous, orange, bright orange, brown or even black with more or less black hairs intermixed (while the two other subgenera have a mesosoma with brown to orange hairs with more or less black hairs intermixed) (Fig. 7 B) as well as terga with hair bands on the apical margins, basally covered by black pubescence on the discs, or entirely covered by pale pubescence of various colour on at least T 2 - 4 (Fig. 7 F) (while the two other subgenera have black hairs on almost all the terga except T 3 - 5 that have portion of the apical margins with appressed white hairs). Finally, Glossamegilla can be distinguished from Micramegilla, Amegilla sensu stricto (partim), Zebramegilla, Megamegilla (partim) and Aframegilla (partim) by the Indo-Malayan distribution (this group of species are mainly distributed in India while the other subgenera are distributed in the Palaearctic and in Africa) and by the clypeus entirely black except sometimes with a small mark basomedially (while the other subgenera have more extended pale clypeal marks compound of an inverted T-shape or a median longitudinal line, only the species from Cape Verde Islands have an entirely black clypeus). If pale paraocular marks are present (Figs 5 C, 8 C, 9 C, 17 C, 18 C, 19 C, 20 C, 21 C, 22 C, 23 C, 24 C), the Glossamegilla can be separated from Zebramegilla (partim), the Micramegilla (partim) and the Dizonamegilla (partim) by their Indo-Malayan distribution while the other subgenera are distributed in Africa and Western Palaearctic. T 1 - 2 can be either entirely black haired without pale hair bands on the apical margins nor appressed brown hairs (sometimes sides of the T 2 can be covered by tuft of white hairs) (Fig. 21 F) or banded with pale hairs on the apical margins (sometimes the T 2 have poorly developed hair bands) (Figs 5 F, 7 F, 10 F, 18 F, 19 F, 20 F, 23 F, 24 F), sometimes most of T 1 - 2 are covered by adpressed brown hairs that can be sometimes very sparse or absent medially. If T 1 - 2 are entirely black haired without pale hair bands on the apical margins nor appressed brown hairs (sometimes sides of the T 2 can be covered by tuft of white hairs), Glossamegilla can be separated from the Dizonamegilla (partim) by the terga being entirely black haired, except for tufts of white hairs on the sides of T 5. If T 1 - 2 are banded with pale hairs on the apical margins (sometimes the T 2 have poorly developed hair bands and sometimes most of T 1 - 2 are covered by adpressed brown hairs that can be sometimes very sparse or absent medially), the Glossamegilla can be differentiated from the Zonamegilla (partim) and Zebramegilla (partim) by (i) a body length of at least 12 mm (while the two other subgenera have a length of ≤ 9 mm), (ii) the mesosoma with ochraceous to bright orange hairs with more or less or without black hairs intermixed (Figs 5 B, 7 B, 10 B, 18 B, 19 B, 20 B, 23 B, 24 B) (while the two others subgenera have a mainly white haired mesosoma with some black hairs intermixed) and (iii) with pale hair bands on the apical margins of the terga that are generally brown (but can also be ochraceous to bright orange) while the discs is at least partially black haired or terga entirely covered by ochraceous to fulvous or brown pubescence that is sometimes denser apically, leading to slightly contrasting hair bands (Figs 5 F, 7 F, 8 F, 9 F, 10 F, 17 F, 18 F, 19 F, 20 F, 22 D, 23 F, 24 F) (while the two others subgenera have pale hair bands on the apical margins of the terga). As previously said, the females are more difficult to determine at the subgenus-level as mainly colouration-based characters are used and these characters vary substantially. However, the biogeographic regions and the size of the galea (that reaches at least the middle of the hind coxa when resting, with the galea ~ 3 × as long as the foretibia when measured from the apex to the maxillary palpus) are powerful diagnostic characters.	en	Carion, Frédéric, Gérard, Maxence, Ghisbain, Guillaume, Wood, Thomas J.

389A45B143DF5EFE9439B847CDE30A6E.taxon	diagnosis	Diagnosis. Male: Unknown. Female: Amegilla celineae sp. nov. is a species without typically contrasting hair bands on T 2 - 4, except on T 3 - 4 where the hair bands are slightly more contrasting (but not as much as in the banded species). Amegilla celineae sp. nov. can be differentiated from both colour forms of A. amymone by the pale clypeal mark more extensive, not restricted to a small triangular paler mark at the apex (while A. amymone have pale clypeal marks restricted to a small triangular paler mark at the apex, sometime with a narrow line of the same colour just above) and terga without apricot-orange pubescence (while A. amymone have apricot-orange pubescence on at least T 4 - 6, sometimes only apically on T 4). Amegilla celineae sp. nov. differs from A. himalajensis (Radoszkowski, 1882) by the pale yellow clypeal marks (while the marks are dark brown in A. himalajensis) as well as the presence of black hairs intermixed in the pubescence of the mesosoma (while A. himalajensis does not have any black hairs intermixed on the mesosoma). Amegilla celineae sp. nov. can be separated from the trio A. insularis, A. pagdeni Lieftinck, 1956 and A. cinnyris by a more protuberant clypeus, in profile view the clypeus equals or slightly exceeds the width of the compound eye (while the trio have a less protuberant clypeus that in profile view is smaller than the width of the compound eye, sometimes only a bit smaller) and the outside of the basitarsus III without black hairs, entirely covered by pale pubescence (while the trio have a basitarsus III at least partially covered by black pubescence). Amegilla celineae sp. nov. differs from A. vigilans by less extended yellow clypeal marks (while A. vigilans have more extended and momre orangish pale clypeal marks), a brighter pilosity (more bright fulvous to bright orange while A. vigilans is more ochraceous to slightly fulvous), terga entirely and more evenly clothed by fulvous to orange pubescence leading to not very contrasting hair bands at the apex of the terga, except on T 3 - 4 where the hair bands are more visible (while A. vigilans have the terga entirely clothed with pale ochraceous pubescence that is slightly denser apically, giving slightly contrasting and poorly-defined hair bands, the hair bands on T 3 - 4 do not contrast more than these on the other terga, hair bands more consistent) as well as hind tibiae orange to pale brown (while A. vigilans have usually dark hind tibiae, neither orange nor pale brown). Amegilla celineae sp. nov. is therefore morphologically close to A. pendleburyi but differs by the mainly impunctate paraocular areas (only a very punctures visible while A. pendleburyi have entirely punctate paraocular areas), the labrum not entirely and evenly punctate with the presence of two impunctate areas on the sides of the labrum (below the two protuberances) (A. pendleburyi have a labrum entirely and evenly punctate), punctation of the clypeus coarser with smaller and hardly visible interspaces (while A. pendleburyi have a clypeus with finer punctation and broader well-visible interspaces), a metasoma with a more uneven pubescence and hair bands at the apex of the terga more contrasting (T 3 - 4 basally covered by a small black haired area) (A. pendleburyi have a more even pubescence, the terga usually do not have any apical contrasting hair bands) as well as a larger size of ~ 19 mm (while A. pendleburyi is smaller, ~ 18 mm maximum).	en	Carion, Frédéric, Gérard, Maxence, Ghisbain, Guillaume, Wood, Thomas J.

389A45B143DF5EFE9439B847CDE30A6E.taxon	description	Description. Male: Unknown Female: Length of 19 mm. Interalar width of ~ 3.8 mm (shorter distance between the base of the tegulae). Head: Labrum rectangular, wider than long (8: 7, 2.4 × 2.1 mm), with two slightly protruding brownish areas at the base, remaining labrum entirely brownish yellow except for the brown transverse carina at the apex of the labrum. Centre of the labrum punctate with a dense and deep punctation (interspaces of at most the diameter of a punctures but generally smaller). Sides of the labrum less punctate with impunctate areas just below the protuberances of the labrum as wells as a less dense punctation on remaining sides with interspaces of at least the diameter of a puncture (generally larger than this diameter). A band on the centre of the labrum covered by long fulvous setae of approximately the size of the diameter of an ocellus, apex of labrum also covered by a band of (denser) hairs that are of the same colour but smaller. Mandibles not bidentate (bi-dentation not visible) and very blunt, almost square, basal 1 / 2 darkened yellow, other 1 / 2 dark brown, and the apex black. Clypeus mainly reddish brown with dark clypeal marks compound of two large sub-rectangular areas, pale clypeal marks on the clypeus resumed to a yellow-orangish inverted T-shape that is a more extended on the area between the paraocular area and the labrum. Clypeus densely and entirely punctate with a coarse and deep punctation (interspaces of ≤ 1 / 2 the diameter of a puncture but generally smaller). Clypeal carina protruding, slightly blunt but not very blunt and impunctate (vertical bar of the yellow T). Clypeus entirely, evenly but sparsely covered by fulvous pubescence with the hairs slightly longer than the diameter of an ocellus. Paraocular areas protruding and yellow, mainly impunctate except at the base, near the insertions of the antennae (punctation similar to the clypeus). Protuberance of the apical margin of the clypeus of approximately the diameter of the eye (or slightly less). Scape anteriorly dark orange or slightly reddish, posteriorly dark brown to black and covered by fulvous to slightly orange pubescence that is longer than the width of the scape. A 2 dark brown to slightly reddish. Anterior surface of A 3 mainly orangish brown, basally with a paler orange area and apically with a narrow ivory-white line; posterior surface dark brown to black. A 4 - 5 basally dark brown and apically orange, ending in a narrow ivory-white line on the anterior surface, posterior surface dark brown to black. A 6 - 12 brown-orange on anterior surface and posterior surface dark brown to black. A 3 - 12 entirely covered by very small, hardly visible, white pilosity. A 2 anteriorly and apically with a small tuft of very small (but larger than the pilosity on the other articles) fulvous hairs. A 3 longer than wide, slightly longer than 4 + 5 + 6. A 4 - 7 shorter than wide. A 8 - 11 squared, as long as wide or very slightly shorter. A 12 not cylindrical, obliquely truncated at the apex. Frons to gena black (except a yellow triangle at the margin of the frons) and not evenly covered by fulvous pubescence of various length that is denser near the apical insertions. Presence of some long black hairs near the ocellus. Genae with very long white to slightly yellow hairs. Mesosoma: Mesosoma entirely covered by bright fulvous-orange pubescence, without any black hairs intermixed in the pilosity of the dorsum. Scutum entirely, finely, and closely punctate with interspaces generally ≤ 1 / 2 the diameter of a puncture. Presence of a depression, the width less than the diameter of a surrounding puncture, on the centre of the scutum that does not go to the end of the scutum. Presence of two small but deep depression on the scutum, on each side, near the tegulae, symmetrical. Scutellum finely and densely punctate with interspaces of generally ≤ 1 / 2 the diameter of a puncture. Presence of a small sharp carina at the centre of the scutellum that does not go on all the length of the scutellum. Cuticle of the mesosoma deep black under the pilosity. Tegulae hyaline brown-fulvous, sparsely and shallowly punctate with interspaces of twice (sometimes more) the diameter of a puncture. Wings sparsely covered by dark hairs on the veins and inside the cells with a denser pilosity on the veins. Apex of the wings covered with very sparse and dark brown protuberances that are not similar to the hairs. Wings translucent but slightly yellow. All legs with an brownish orange cuticle, except for the hind tibiae that are exteriorly a bit darker and the basitarsi that are deep brown. All legs exteriorly covered by bright orange-fulvous pubescence and interiorly covered with a slightly darker pubescence. Tarsal claws of all the basitarsi bidentate with the second tooth situated on the middle of the main claw. Apex of mid tibia with one long and thick almost hyaline brown spine which is crenulate on one side and smooth on the other side; the spine is curved at the apex. Apex of hind tibia with two long and thick almost hyaline brown spines which are crenulate on one side and smooth on the other side; spines curved at the apex. Metasoma: T 1 entirely and evenly covered by short fulvous pubescence except on the side where there are longer hairs of the same colour. T 2 almost entirely covered by short fulvous pubescence, except a little patch of short black hairs on the centre. Discs of T 3 - 4 at least partly covered by short black pubescence, the pale pubescence on the apical part forms hair bands that are wider at the centre of the terga. Some fulvous hairs are intermixed with the black hairs of T 3 - 4, the hairs become longer when going towards the sides of T 4. T 5 mainly black-haired with short black hairs, laterally with two fulvous hair tufts composed of sparse hairs. T 1 - 5 entirely, evenly, and sparsely punctate with shallow punctation and interspaces several times the diameter of one puncture. Integument of the terga mainly black but some parts of some apical margins are brown to ochraceous it is therefore highly probable that the apical margins were originally deep brown to ochraceous in fresh specimen (similarly to A. pendleburyi and A. feronia) but the integument decoloured with the time. All sterna mainly glabrous, hairs limited to sparse band at the apex of some sterna (2, 4 – 6). Integument of all the sterna dark brown to orangish but not dark. S 1 - 3 with only a few sparse punctures on the discs, the apical margins and sometimes the sides more densely punctate but with interspaces of approximately the diameter of a puncture. S 4 more densely punctate at the apex and less densely at the base, interspaces become wider towards the base with only a few sparse punctures. S 5 densely punctate at the apex and on the sides but interspaces become wider towards the base with only a few sparse punctures. S 6 - 7 entirely, evenly, and densely punctate with interspaces of at most the diameter of a puncture (generally less).	en	Carion, Frédéric, Gérard, Maxence, Ghisbain, Guillaume, Wood, Thomas J.

A9A7F5E0945256A3A3673A42DBF0750B.taxon	diagnosis	Diagnosis. Male: The male of A. floresiana sp. nov. is a species with contrasting pale hair bands on the metasoma (sometimes a little obscured by the surrounding pale pilosity) and the tergal discs usually partially covered by black pilosity. This produces an effect of hair bands that are poorly defined but clearly present. This species differs from the group of A. jacobi / A. sumatrana by the wider and more ochraceous to fulvous hair bands, the tergal discs being less covered by black pilosity than in these comparison species. Amegilla floresiana sp. nov. can be differentiated from the group of A. feronia and A. cyrtandrae by the larger size (~ 18 mm for A. floresiana sp. nov. while A. feronia and A. cyrtandrae are ~ 15 – 17 mm) and a more protuberant clypeus which in profile view equals or exceeds the width of the compound eye (while the clypeus is less protuberant in A. feronia and A. cyrtandrae, with a protuberance smaller than the width of the compound eye); the pale pubescence of mesosoma and metasoma also varies from ochraceous to fulvous for A. floresiana sp. nov. (while it varies from fulvous to bright orange for A. feronia and A. cyrtandrae). Finally, this species differs from A. gigas and the dark form of A. vigilans by the labrum slightly wider than long (in the two comparison species with the labrum as wide as long), a fine (not coarse) punctation of the clypeus with large interspaces of at least the diameter of a puncture (while the two comparison species have a coarse and not very sparse punctation with rather smaller interspaces of at most the diameter of a puncture but generally less), wider and very poorly defined hair bands with a small parts of the tergal discs with black hairs or no black hairs at all as well as, sometimes, a brighter pilosity (from ochraceous to bright orange-fulvous) (while A. gigas and the dark form of A. vigilans have narrower and more sharply defined hair bands with a larger black haired area on the discs that is always present as well as a less bright pilosity (from ochraceous to very slightly orange )). Female: As for the male, the female of A. floresiana sp. nov. is a species with contrasting pale hair bands on the metasoma (sometimes a little obscured by the surrounding pale pilosity) and the tergal discs partially covered by black pilosity. This produces an effect of hair bands that are poorly defined but clearly present. This species differs from the group of A. jacobi / A. sumatrana by the wider and more colourful hair bands, the tergal discs being less covered by black pilosity than in these species. Amegilla floresiana sp. nov. can be differentiated from the group of A. feronia, A. cyrtandrae and A. suzanneae Carion & Wood, sp. nov. by the larger body size (~ 17 – 18 mm for A. floresiana sp. nov. while A. feronia, A. cyrtandrae and A. suzanneae sp. nov. are ~ 13 – 16 mm) and a more protuberant clypeus which in profile view equals or exceeds the width of the compound eye (while the clypeus is less protuberant in A. feronia and A. cyrtandrae, with a protuberance smaller than the width of the compound eye). Amegilla floresiana sp. nov. differs from A. gigas by a sharper and more protruding clypeal carina that thus does not appear flat (while in A. gigas the clypeal carina is very flat, not sharp at all, and does not protrude very much or not at all), more extended and ivory-yellow to yellow clypeal marks and entirely punctuate paraocular areas (while A. gigas have less extended and yellowish, tending to dark yellow, pale clypeal marks, the face is mainly dark; A. gigas have restricted ivory-white spots on the paraocular areas as well as a clear shining area between the punctation of the paraocular areas and the transition with the clypeus). Finally, A. floresiana sp. nov. can be distinguished from the dark form of A. vigilans by rather poorly defined hair bands at the apex of the terga that are wider than for A. vigilans with pale pilosity covering the majority of the discs of the terga and almost the entirety of T 4 (while A. vigilans have rather sharply defined and narrower hair bands with the discs of the terga more covered by black pubescence), the pale clypeal marks less extended and ivory-yellow to yellow (while A. vigilans have more extended yellow-orange pale clypeal marks), a finer punctation of the clypeus with larger interspaces approximately the diameter of the punctures (A. vigilans have a clypeus with a coarser, less defined punctation with smaller interspaces of generally ≤ 1 / 2 the diameter of a puncture), paraocular areas of the same colour than the clypeal marks but the colouration is less extended than in A. vigilans (A. vigilans also has the paraocular areas of the same colour than the clypeal marks but the colouration is more extended) and a pubescence usually brighter, more fulvous to orange but can sometimes also be ochraceous, similarly to A. vigilans which have a pubescence ochraceous to slightly fulvous.	en	Carion, Frédéric, Gérard, Maxence, Ghisbain, Guillaume, Wood, Thomas J.

Mandibles bidentate, both teeth blunt, not strongly sharp, the secondary tooth sometimes less developed but still visible. Mandibles ivory-yellow on the basal 1 / 2 and deep brown on the apical 1 / 2. Clypeal marks variable, clypeus either more yellow than dark or more dark than yellow but the two subrectangular black clypeal marks always present.

9D24BD9CDE6554799F4229AC033AE161.taxon	diagnosis	Diagnosis. Male: The male of A. gigas shows strongly contrasting hair bands, with only black hairs on the discs T 2 - 4 while T 1 is entirely covered by pale fulvous pubescence. Amegilla gigas differs from A. jacobi and A. sumatrana by the wider and more colourful (fulvous in A. gigas, white to slightly ochraceous in A. jacobi and A. sumatrana) hair bands at the apex of the terga as well as a slightly smaller black-haired area. Amegilla gigas also differs from A. feronia and A. cyrtandrae by the more strongly protuberant clypeus of, in profile view, ~ 1.3 × bigger than the width of the compound eye (A. feronia and A. cyrtandrae have a less protuberant clypeus that is, in profile view, smaller than the width of the compound eye) and a larger body size of ~ 18 mm (while A. feronia and A. cyrtandrae are ~ 15 – 17 mm maximum). Amegilla gigas can be distinguished from A. floresiana sp. nov. by the labrum as long as wide (1: 1, while A. floresiana sp. nov. have a labrum slightly wider than long; ~ 17: 16 – 19: 18), a coarser punctation of the clypeus that is not very sparse with interspaces of at most the diameter of a puncture (A. floresiana sp. nov. have a fine punctation that is also very sparse with large interspaces of at least the diameter of a puncture) as well as the tergal hair bands narrower and more sharply defined with the black-haired area on the tergal discs larger and more consistently present (A. floresiana sp. nov. have wider and poorly defined tergal hair bands at the apex of the T 2 - 4 with a small black-haired basal part the discs, sometimes some or all the terga do not have a black-haired area and are entirely covered by the pale pubescence). Finally, A. gigas can be distinguished from the dark form of A. vigilans by a more protuberant clypeus of ~ 1.3 × bigger than the diameter of the eyes (1: 1 in A. vigilans), yellow clypeal marks that are very extended with only a small dark mark and one narrow brown line on each side of the clypeal carina (A. vigilans have pale yellow to orange less extensive pale marks and two sub-rectangular black marks), a pilosity in general more bright (rather fulvous to slightly orange in A. gigas, ochraceous in A. vigilans) as well as a dorsal pubescence of the mesosoma without or with only few black hairs intermixed (while A. vigilans have more black hairs intermixed in the dorsal pubescence of the mesosoma).	en	Carion, Frédéric, Gérard, Maxence, Ghisbain, Guillaume, Wood, Thomas J.

With the discovery of the supposed male of A. gigas, the distribution of this species is enlarged to the island of Timor and more specifically the country of Timor-Leste. The species was originally known from the island of Wetar (Friese 1922). As discussed for the type series, the specimen from Sumatra is not considered as conspecific; therefore, this species is not distributed in Sumatra.	en	Carion, Frédéric, Gérard, Maxence, Ghisbain, Guillaume, Wood, Thomas J.

28335E8421E75182876D07FE369BB017.taxon	diagnosis	Diagnosis. Male: Unknown. Female: Amegilla suzanneae sp. nov. is morphologically close to A. pendleburyi but differs by a less protruding clypeal carina (while the clypeal carina protrudes more in A. pendleburyi), the scape anteriorly dark brown or ivory-white but never orange (A. pendleburyi with scape anteriorly orange) and the presence of black hairs on tergal discs, placing it in the group of species displaying hair bands. In the key, A. suzanneae sp. nov. is artificially put close to A. feronia due to the presence of hair bands, the usually paler hind tibiae, and the fact that they are both closely morphologically related to A. pendleburyi. Amegilla suzanneae sp. nov. differs from A. feronia by the pale clypeal marks ivory-yellow to yellow (while these marks are clearly yellow or even slightly orange to orange on A. feronia), the scape ivory-yellow to yellow also but sometimes dark brown (A. feronia have anteriorly orange scape) and the hair bands less sharply defined basally with the pale pilosity more extended and the black pilosity more restricted (A. feronia have wider black-haired areas on the tergal discs as well as narrower and basally more sharply defined hair bands on the apical margins). Amegilla suzanneae sp. nov. also generally have a less bright, fulvous to slightly orange, pilosity while A. feronia have a brighter, bright orange, pilosity. Amegilla suzanneae sp. nov. can be distinguished from A. sumatrana and A. jacobi by the wider and more colourful (fulvous) hair bands, the tergal discs being less covered by black pilosity than in these species. Amegilla suzanneae sp. nov. can be distinguished from the trio A. floresiana sp. nov., A. gigas and A. vigilans dark form by being a smaller species of ~ 16 mm (while the trio is ~ 17 – 18 mm) and having a clypeus less protuberant, in profile view smaller than the width of the compound eye (while the trio have a clypeus more protuberant that, in profile view, equals or exceeds the width of the compound eye). Amegilla suzanneae sp. nov. differs from A. cyrtandrae by the ivory-yellow to orange pale marks that are slightly less extended (while A. cyrtandrae have ivory-white to pale ivory-yellow clypeal marks that cover a slightly larger surface of the clypeus), a scape usually ivory-yellow to yellow anteriorly but that can also be dark brown (while A. cyrtandrae have a dark / black scape anteriorly) and a dorsal pilosity of the mesosoma bright (bright fulvous to bright orange) with fewer dark hairs intermixed (while A. cyrtandrae have a dorsal pilosity of the mesosoma pale with many black hairs intermixed).	en	Carion, Frédéric, Gérard, Maxence, Ghisbain, Guillaume, Wood, Thomas J.

28335E8421E75182876D07FE369BB017.taxon	description	Description. Male: Unknown. Female: Length of 16 – 17 mm. Interalar width of ~ 3.9 – 4 mm (shorter distance between the base of the tegulae). Head: Labrum rectangular, wider than long (17: 20 – 19: 20, 1.7 × 2 mm – 1.9 × 2 mm, thus sometimes hardly visible), with two not really protruding brownish to almost black areas at the base, remaining labrum variable from entirely ivory-yellow to orange except for the black transverse carina at the apex of the labrum and sometimes a dark brown to black band that can vary in width just before the labral carina. Labrum entirely, evenly, and densely punctate with interspaces of approximately or less than the diameter of a puncture (the colouration of the labrum makes it sometimes difficult to see). Labrum entirely covered by relatively dense ochraceous pubescence, the setae are approximately or slightly longer than the diameter of an ocellus. Mandibles bidentate but take care that the second tooth is sometimes blunt and / or partially covered by the labrum leading to an hardly visible character. Mandibles pale (ivory-yellow to orangish yellow) on the basal 1 / 2 and black on the apical 1 / 2 (sometimes only black on the apical 1 / 3). Clypeus mainly black to reddish brown with dark clypeal marks compound of two large sub-rectangular areas, the pale clypeal marks on the clypeus are resumed to an ivory-yellow to yellow-orange inverted T-shape that is more extended on the area between the paraocular area and the labrum. Clypeus entirely, finely, and relatively densely punctate with interspace of at least the diameter of a puncture. Clypeal carina only slightly protruding, rather blunt (but not as much as in A. gigas) and impunctate (vertical bar of the pale T). Clypeus entirely, evenly, and relatively densely covered by an ochraceous pubescence with some black hairs intermixed (length of the hairs variable). Paraocular areas not protruding and pale (ivory-yellow to yellow) only on the apical 1 / 2, near the clypeus. Paraocular areas evenly, entirely, and densely punctate with interspaces of ~ 1 / 2 the diameter of a puncture (sometimes hardly visible through the pubescence). Clypeus not strongly protuberant, in lateral view protuberance of the apical margin of the clypeus less than the diameter of the eye. Scape pale on the anterior surface, sometimes with an ivory-yellow to yellow area surrounded by a dark brown integument or only a dark brown integument but never black and posteriorly dark with a black integument. Scape anteriorly with a carina around the centre of the anterior surface. Scape entirely covered by fulvous pubescence of at most the width of the scape, the pilosity is denser while going towards the sides of the scape but less dense on the anterior surface. A 2 entirely black or sometimes at least partly brownish reddish anteriorly. Anterior surface of A 3 basally black and paler (brown) on the apical 1 / 3, sometime presence of a very narrow ivory-white line at the apex of the article, posterior surface black. A 4 - 12 brown-orange on anterior surface and posterior surface black. A 3 - 12 entirely and evenly covered by very small, hardly visible, white pilosity. A 2 anteriorly and apically with a small tuft of very small (but larger than the pilosity on the other articles) ochraceous to fulvous hairs. A 3 longer than wide, equal to slightly longer than 4 + 5 + 6. A 4 - 5 shorter than wide. A 6 - 11 squared, approximately as long as wide. A 12 not cylindrical, obliquely truncated at the apex. Frons to gena black (except an ivory-yellow to yellow-orange triangle or inverted T at the margin of the frons) and rather evenly covered by an ochraceous to fulvous pubescence of various length that is denser near the antennal insertions. Some long black hairs intermixed in the pale pubescence near the ocelli. Presence of a relatively shallow depression that goes from the middle ocellus to the pale mark of the frons, width of approximately the diameter of a surrounding puncture, the carina hardly showing through the pubescence. Genae with very long white to slightly yellow hairs. Mesosoma: Mesosoma entirely covered by fulvous-orange pubescence, with some to many black hairs intermixed in the pilosity of the dorsum. Scutum and scutellum entirely, finely, and closely punctate with interspaces generally ≤ 1 / 2 the diameter of a puncture. Presence of a depression, the width less than the diameter of a surrounding puncture, on the centre of the scutum that does not go to the end of the scutum. Cuticle of the mesosoma deep black under the pilosity. Tegulae hyaline ochraceous to hyaline deep brown, sparsely and shallowly punctate with interspaces of at least one diameter of a puncture. Tegulae sparsely and entirely covered by ochraceous or black pubescence. Wings sparsely covered by dark hairs on the veins and inside the cells with a denser pilosity on the veins (the apical part of the cells is covered by hairs generally). Apex of the wings covered with very sparse and dark brown protuberances that are not similar to the hairs. Wings translucent but slightly yellow. Colours of the cuticle of the legs variable from brown to dark brown, some parts sometimes even black. All legs exteriorly covered by bright orange-fulvous pubescence and interiorly covered with a slightly darker to black pubescence. Tarsal claws of all the tarsi bidentate with the second tooth situated on the middle of the main claw. Tarsal claws very sharp, the secondary fore-claw is very long, 1 / 3 less than the main one while the other secondary claws are only 1 / 3 of the main one. Main claws arched, with a small tubercle on the ventral surface just above the secondary claw. Apex of mid tibia with one long and thick black spine which is crenulate on one both sides; the spine is curved at the apex. Apex of hind tibia with two long and thick black spines which are crenulate on both sides; spines curved at the apex. Metasoma: T 1 entirely covered by short ochraceous to fulvous pubescence except on the sides and on the base of the discs where there are longer hairs of the same colour. T 2 almost entirely covered by short ochraceous to fulvous pubescence with at least a small zone of black hairs at the basal centre of the disc (that can be almost all the width of the tergum sometimes), leading to more or less hair bands at the apex of the tergum. T 3 - 4 with wide ochraceous to fulvous short pubescence, pale pubescence a little bit more expanded on the sides of these terga, disc of the terga generally mainly black haired (with some pale hairs intermixed) except sometimes on the T 4 where the centre of the tergum is widely covered by the pale pubescence (with some black hairs intermixed). T 5 generally black haired, sometimes with ochraceous pubescence widely intermixed. T 1 - 5 entirely, evenly, and sparsely punctate with shallow punctation and interspaces of at least the diameter of one puncture. Integument of the terga mainly black but the apical margin sometimes slightly paler or ochraceous on T 1 - 4 it is therefore highly probable that the apical margins were originally deep brown to ochraceous in fresh specimen (similarly to A. pendleburyi and A. feronia) but the integument decoloured with the time. All sterna with hair bands on the apical margin, pilosity ochraceous on S 1 - 5, black on S 6 and brownish and very dense on S 7. Sides of S 3 - 5 with ochraceous hair tufts. Integument of S 1 - 2 ochraceous-yellow, S 3 - 5 brown, basal 1 / 2 of S 6 brown, apical 1 / 2 and S 7 black. All the sterna can also be deep brown to black with apical margin pale (ochraceous) or not. S 1 - 2 mainly impunctate with only some small areas with very close and shallow punctation on the centre of the sterna. Sides and apex of S 3 - 4 densely and evenly punctuate with interspaces of approximately the diameter of a puncture (but sometimes more and sometimes less), basal 1 / 2 of these sterna very sparsely punctuate with interspaces generally several times the diameter of a puncture. S 5 densely punctuate but with some interspaces larger than the diameter of a puncture. S 6 - 7 more densely, entirely, and evenly punctuate with interspaces of at most the diameter of a puncture.	en	Carion, Frédéric, Gérard, Maxence, Ghisbain, Guillaume, Wood, Thomas J.

45946ABF5D01560897666E526C14A1B4.taxon	diagnosis	Diagnosis. Male: The male of A. vigilans usually do not have very contrasting hair bands at the apex of the terga, the tergal discs are entirely covered by pale ochraceous pubescence intermixed with sparse black hairs, the pale pubescence a little bit more dense at the apex of the terga but not forming a very contrasting hair bands (integument normally ochraceous at the apex, accentuating the pubescence, giving an impression of hair bands). Amegilla vigilans can be separated from A. himalajensis by the deep black dark clypeal marks that are sharply defined compared to the paler ivory-yellow to slightly salmon pale clypeal marks (while A. himalajensis have dark brown clypeal marks that does not contrast from each other), a dorsal pubescence of the mesosoma with black hairs intermixed (while A. himalajensis does not have any black hairs intermixed on the mesosoma) and all the terga entirely covered by ochraceous pubescence (while A. himalajensis only have T 1 - 2 partly or wholly and sides of T 3 covered by orange pubescence). Amegilla vigilans can be distinguished from both colour forms of A. amymone by the less extended pale clypeal marks that are either ivory-yellow or orange (but never ivory-white like in A. amymone), the two sub-rectangular dark clypeal marks (absent in A. amymone, dark clypeal marks different than two sub rectangular areas), an ochraceous pubescence of the mesosoma (black to dark brown with many black hairs intermixed in A. amymone) and an absence of apricot-orange pubescence on the terga (while A. amymone have apricot-orange pubescence at least on T 4 - 6). Amegilla vigilans can be distinguished from the trio A. insularis, A. pagdeni, and A. cinnyris by a more protuberant clypeus of approximately the width of the compound eye (while the trio have a clypeus smaller than the width of the compound eye) and a basitarsus without any black pilosity, the pilosity entirely ochraceous (while the trio have at least some black hairs on the basitarsus III). Finally, A. vigilans can be separated from A. pendleburyi by the more extended, ivory-yellow to slightly salmon, pale clypeal marks (A. pendleburyi with clypeal mark less extended, especially the central line which is narrow, unlike in A. vigilans where the central mark is too thick to be labelled as a line), the pilosity that is paler, rather ochraceous to slightly yellow (while A. pendleburyi have a more fulvous-orange pilosity) as well as the terga entirely covered with a pale ochraceous pubescence that is denser apically, giving slightly contrasting and poorly defined hair bands (A. pendleburyi have terga entirely and more evenly covered by fulvous-orange pilosity, leading to the absence of contrasting hair bands). The dark form of A. vigilans is a banded form of Amegilla close to A. gigas concerning the habitus but can be separated from this species by a less protuberant clypeus of, in profile view, approximately the width the compound eye (while A. gigas have, in profile view, a clypeus that exceeds the width of the compound eye), pale orangish clypeal mark that are less extended leading to two sub-rectangular dark clypeal marks (while A. gigas have yellow, very expanded, pale clypeal marks and dark clypeal marks restricted to two small black to slightly reddish marks and two thin brown lines), a pilosity less bright in general (more ochraceous-yellow for A. vigilans while the pilosity is more fulvous to slightly orange in A. gigas) as well as a dorsal pubescence of the dorsum of the mesosoma with more black hairs intermixed (fewer black hairs intermixed in the pilosity of the dorsum of the mesosoma in A. gigas).	en	Carion, Frédéric, Gérard, Maxence, Ghisbain, Guillaume, Wood, Thomas J.

Head: Labrum rectangular, slightly wider than long (18: 17 – 21: 20, 1.8 × 1.7 mm – 2.1 × 2 mm, thus sometimes hardly visible, can be considered squared without measurements) with a protruding base (with two brown or yellow areas, one on each side of the base) giving a curved appearance to the labrum in lateral view. Remaining labrum yellow or brownish orange (dark form), except the black transverse carina at the apex of the labrum and a narrow deep brown band at the base, brown band at the base absent in the dark form. Labrum entirely, evenly, and densely punctate with interspaces of the size of a puncture or less. Labrum entirely covered by a not very dense and ochraceous pubescence that is equal or shorter than the diameter of an ocellus. Mandibles bidentate and blunt, giving teeth a rounded apex, yellow on the basal 2 / 3 and deep brown to black on the apical 1 / 3 (darkened yellow to brown on the base for the dark form).

The depression hardly showing through the pubescence. Genae with very long white to ochraceous hairs (especially long under the eyes). Mesosoma: Mesosoma entirely covered by ochraceous and dense pubescence with a variable number of black hairs intermixed (but always with at least some black hairs present) in the pilosity of the dorsum. Scutum and scutellum finely and closely punctate with interspaces of generally at most the diameter of a punctures (but can be wider on some areas of scutum and scutellum). Cuticle of the mesosoma deep black under the pilosity. Tegulae hyaline deep brown, sparsely and shallowly punctate with interspaces of at least one diameter of a puncture. Tegulae relatively densely and entirely or partially covered by ochraceous pubescence. Wings relatively sparsely covered by dark hairs on the veins and inside the cells with a denser pilosity on the veins (most parts of the cells covered by pubescence). Apex of the wings covered with very sparse and dark brown protuberances that are not similar to the hairs. Wings translucent but slightly yellow. Cuticle of all the legs deep brown to dark brown, never pale. All legs exteriorly covered by ochraceous to slightly fulvous pubescence and interiorly covered with a slightly darker to black pubescence, hind basitarsi without black hairs exteriorly. Tarsal claws of all the basitarsi bidentate with the base of the second tooth situated on the middle of the main claw. Tarsal claws very sharp, the secondary claws are very long, 2 / 3 the length of the main one. The main claws arched but without any tubercles. Apex of mid tibia with one long and thick deep brown (dark form) to black (pale form) spine which is crenulate on both sides; the spine is slightly curved at the apex. Apex of hind tibia with two long and thick deep brown (dark form) to black (pale form) spines which are crenulate on both sides; spines slightly curved at the apex. Metasoma: For the pale form, T 1 - 6 entirely covered by short ochraceous pubescence that is denser on the apical margin for T 1 - 5, leading to slightly contrasting hair bands on these terga. Absence of dark hairs on discs of T 1 - 6 for the pale form. For the dark form, disc of T 1 basally and centrally covered by short black pubescence, laterally and apically covered by ochraceous short pubescence that is denser apically creating a wide but poorly contrasted hair band. T 2 - 5 covered by black pubescence on the disc and covered by ochraceous pubescence on the apical margin, leading to a strongly contrasted hair band. T 6 entirely covered by brown pubescence. T 1 - 6 entirely, evenly, and sparsely punctate with shallow punctation and interspaces of at least the diameter of one puncture. T 7 (pygidial plate) with two spine-like structures. Integument of T 1 - 6 deep brown to dark brown, sometimes the apical margins is paler (brown to ochraceous) it is therefore probable that the apical margins were originally deep brown to ochraceous in fresh specimen (similarly to A. pendleburyi and A. feronia) but the integument decoloured with the time. All the sterna entirely covered by short and relatively dense ochraceous pilosity (sometimes the S 1 - 3 not entirely covered).
