03CC87B4FFF2FFBCFE4EFC35C518FA4A.taxon	discussion	Remarks. Described from both male and female syntypes from the collection of J. C. Gundlach and deposited in the collection of the Cuban National Museum of History of Sciences (Havana), which have not been examined. EPK examined the specimen from MCZ in 2001; it is still unclear if it is one of the Cuban specimens determined by Loew after 1868. Hendel’s description of E. wettsteinii fits the original description and morphology of E. abdominalis, except the syntergite 1 + 2 entirely black (partly brownish yellow in E. abdominalis). However, in three of four females from Hiquito, San Mateo (Costa Rica) here determined as E. abdominalis, the abdomen is entirely black as in E. wettsteini, showing that their differences may be only a result of individual variability.	en	Korneyev, Severyn V., Hauser, Martin, Kameneva, Elena P., Gaimari, Stephen D.

03CC87B4FFF4FFBEFE5BFE10C38EFE72.taxon	discussion	Remarks. Walker (1861) described O. leucomelas based on an unknown number of specimens of unknown sex as follows: “ Nigro-viridis, antennis pedibus que nigris, tarsis piceis, alis albis nigro-quadrifasciatis, fascia 1 â basali, 2 â 3 â que posticèdilatatis, 4 â costali; halteribus albis. Blackish-green; antennae and legs black; tarsi piceous; wings white, with four black bands; first band near the base; second broad, much dilated hindward; third narrow, also dilated hind- ward; fourth costal, joining the third at much beyond half the length of the costa, and extending thence to a little beyond the tip of the wing; discal transverse vein parted by one-fourth of its length from the border, and by more than twice its length from the praebrachial transverse vein; halteres white. Length of the body 2 ½ lines; of the wings 4 lines. South America. ” Wulp (1899) described his species (as E. fascipennis) as follows, and provided the figure reproduced here (Fig. 1 b): “ Metallic bluish-black; frons and antennae rufous; legs blackish; wings hyaline, with four blackish bands, the discal and subapical much enlarged towards the hind margin, the fourth at the tip of the wing and narrower than the hyaline space before it. Length 3. 5 mm. Closely related to E. latifasciata and agreeing with it in most of its characters. The metallic coloration is more obscure, but on the face it is more extended; the tip of the scutellum is not rufous; the abdomen is more shining black; the legs are blackish, the femora with metallic green reflections, the base only of the tarsi rufous (in one of the specimens, perhaps a not fully coloured one, the legs are rufous). The discal and subapical bands on the wings, though enlarged towards the hind margin, are narrower than in E. latifasciata, and the hyaline space between the subapical and apical ones is much broader than the bands themselves. The apical joint of the ovipositor of the female is cylindrical and rufous. ” Both nominal species were considered synonyms by Steyskal (1968) in his Neotropical Catalogue based on the study of the types from the NHMUK, but without designation of lectotypes. Walker (1861) did not state the number or sex of his type specimens, so the single specimen in the Saunders collection labeled as this species formally has the status of syntype. The Data Portal of the NHMUK (BMNH 2021 a, b, c) refers to “ holotype ” and “ lectotype and paralectotypes ” of both nominal species, but they are all actually syntypes.	en	Korneyev, Severyn V., Hauser, Martin, Kameneva, Elena P., Gaimari, Stephen D.

03CC87B4FFF7FFB0FE4AFE15C2D4FA2A.taxon	discussion	Remarks. Hendel (1909: 155) differentiated this species from E. sororcula as having: “ die Spitzenbinde ist breiter als der glashelle Zwischenraum davor. Aussenrand der zweiten Querbinde concav ” [the apical band wider than the hyaline interspace before it. Outer edge of the second crossband concave]. He described the species as closely related to E. sororcula and E. latifasciata and easily confused with them. It is distinguished from the former by the always slightly concave, non-convex outer edge of the discal wing band, the shape of the subapical crossband, which is much wider posteriorly and covers the crossvein dm-m almost in the middle, not at the proximal edge, and the much wider apical band, which is always wider than the narrow hyaline interspace before it. In E. sororcula, according to Hendel (loc. cit.), the interspace between the discal and subapical bands is more oblique and curved in a way that its concavity is on the proximal margin. The costal band is narrower than the interspace proximal to it. Hendel (1909) mentions that E. latifasciata differs according to the description and illustration by the scutellum reddish posteriorly and reddish legs, whereas E. obliquestriata fits Loew’s description of E. sororcula. The wing pattern of E. latifasciata resembles that of E obliquestriata except for the shape of the hyaline interspace proximal to the wing apex, which is concave outside instead of on the inside. Body (without ovipositor) and wing 4 – 5 mm long (Hendel, 1909: 167). Steyskal (1974) described E. mazorca as follows: “ Length of wing 4.0 – 4.8 mm. Agrees with E. obliquestriata in basic pattern of wing, interantennal space of same color as lower parts of face (not dull black), wholly dark metallic blue-green abdomen, and largely black legs. Head as in Fig. 2; largely yellowish, metallic greenish on frontal triangle, parafrontal plates, vertex, and occiput; middle of face and sides of clypeus infuscated to variable extent; antenna usually wholly orange, but 3 rd segment sometimes a little infuscated above; front largely almost polished, narrow orbits silvery tomentose. Thorax wholly metallic greenish, mesoscutum lightly pale grayish tomentose with indistinct more blackish arcuate postsutural transverse band, especially evident above wing bases; scutellum blackish. Angle between line connecting posterior dorsocentral bristles and each acrostichal bristle 45 °. Legs largely metallic greenish; forecoxa (except basilateral oval dark spot), most of inner face of forefemur, fore- and midbasitarsi, hindbasitarsus (except more or less of tip), and distal end of forefemur tawny. Wing as in Fig. 1 [= Fig. 2 b in the present work] medial hyaline band attaining costa in nearly full width, impinging on only small apical part of 1 st vein (R 1); preapical hyaline band somewhat narrower than apical brown band; section of 4 th vein crossing preapical hyaline band about equal in length to apical section in brown area; length of apical brown area in discal cell less than half as great on 5 th vein as on 4 th vein; brown area in base of 2 nd costal cell squarish, not extended along costa; extension of tip of anal cell about as long as greatest width of cell. Abdomen wholly metallic bluish green, very lightly pale tomentose. ” Steyskal wrote that the type series of E. mazorca had previously been identified as E. obliquestriata. Nonetheless, he did not compare these two nominal species at all. In 2001, EPK studied the type series of both E. obliquestriata and E. mazorca and found no essential characters to distinguish them; all the minor differences in coloration and wing pattern are variable, leaving no gap between them. We consider these species to be conspecific and thus the names to be synonyms. The wing depicted in Hendel (1910) (see Fig. 2 a) has some differences from our illustration made from the same wing of the same specimen (Fig. 2 c) and does not show differences from that of E. mazorca.	en	Korneyev, Severyn V., Hauser, Martin, Kameneva, Elena P., Gaimari, Stephen D.

03CC87B4FFF7FFB0FE4AFE15C2D4FA2A.taxon	biology_ecology	Biology and Economic Importance. Euxesta obliquestriata is considered a major pest of sweet corn (Díaz 1982, Huepe et al. 1986 [as E. mazorca]), along with some other Chaetopsis and Euxesta species, but it is not clear if they infest corn only as secondary invaders, together with the other species, or as independent pests. Also, it is not always clear whether the species was identified by an expert, and therefore some specimens reported in the literature as E. obliquestriata may refer to other species. However, it is obvious that it is widespread throughout the tropics of the New World, where it is a native pest associated with corn plantations not treated with pesticides.	en	Korneyev, Severyn V., Hauser, Martin, Kameneva, Elena P., Gaimari, Stephen D.

03CC87B4FFFBFFB2FE71FF1DC07EFC62.taxon	discussion	Remarks. As noted above, E. wettsteini differs from E. abdominalis only by the syntergite 1 + 2 entirely black (instead of dirty yellow in E. abdominalis). Three of the four females in a series from Costa Rica have entirely black abdomens as in E. wettsteini, and one female has yellowish base of abdomen as in the three males; all the specimens here identified as E. wettsteinii are also females that possibly shows their differences to be only a result of sexual dimorphism or individual variability (including geographical). We do not formally synonymize these two names, as additional studies of larger series including the genital characters are needed.	en	Korneyev, Severyn V., Hauser, Martin, Kameneva, Elena P., Gaimari, Stephen D.
