BB06B339FFBBFFA1FF0EFF13FBF2FDF0.taxon	diagnosis	Diagnosis. The male genitalia of the species-group are characterised by the weakly sclerotised tegumen with narrow arms, the well-developed distal costal process separated from the valvula, the smooth and simple distal saccular process, and the phallus vesica bearing one or two blade- or thorn-shaped cornuti. In the female genitalia, the antrum is large and heavily sclerotised, the corpus bursae has a posterior section having a broad sclerotised plate and bearing clusters of robust spines posteriorly, and the anterior section of the corpus bursae is densely covered with minute spinules. The 7 th abdominal female sternite bears lateral sclerotised and gelatinous pockets that receive the distal processes of the male valva during copulation. Note. The species-group is considered here in wide sense. The volume of this taxonomically difficult complex remains unclear and will be clarified later in the separate paper. Currently we can assign with the group the taxa listed below.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFBDFFA0FF0EFDA6FEE9FE44.taxon	discussion	Taxonomic notes. Three morphologically similar species, M. neoseriata, M. paraseriata and M. pseudoseriata were described in the same book (Kirti & Singh 2016). The latter two species were described from Sikkim and Assam, respectively. Unfortunately, the genitalia illustrations provided by the authors for these two species were accidentally confused and, moreover, the vials with the genitalia were mixed up, which made the interpretation of the aforementioned taxa problematic. However, the examination of additional specimens from various localities in Northeast India made it possible to establish the identity of these taxa and state that pictures of the genital capsules of M. paraseriata and M. pseudoseriata have been swapped with each other in the original descriptions (Kirti & Singh 2016: 93, 94). As a result, M. pseudoseriata turned out to be conspecific to M. neoseriata as the holotypes of these taxa display no recognisable morphological differences (Figs 1, 2, 95, 96) and were collected in the same locality in the same season. Both the taxa were described in the same publication therefore, as the First Revisers (see the Article 24.2.2 of ICZN (1999 )) we hereby determine the precedence of the name M. neoseriata and synonymise M. pseudoseriata with it.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFBDFFA0FF0EFDA6FEE9FE44.taxon	diagnosis	Diagnosis. The forewing length is 10.5 – 11.0 mm in males and 11.0 mm in females. Miltochrista neoseriata is superficially very similar to M. gopaldhara sp. nov., M. mawphlang sp. nov., M. paraseriata and M. terminata Moore, 1878 and the reliable identification requires the examination of the genitalia structures. The diagnostic comparison with M. gopaldhara sp. nov. and M. mawphlang sp. nov. is provided below under diagnoses of those species whereas the genitalia of M. paraseriata and M. terminata are largely different from those of M. neoseriata (see Figs 109, 110, 123 – 126). The male genitalia structure of M. neoseriata is most similar to M. aureata, from which the current species differs superficially in the somewhat broader forewing with markedly more distinct markings. In the male genital capsule, M. neoseriata is distinguished from M. aureata by the uniformly narrow uncus (it is medially dilated in the congener), the noticeably more medially convex dorsal margin of the valva, the more downcurved distal costal process, and the markedly narrower distal saccular process. The phallus vesica of M. neoseriata is narrower than in M. aureata and bears more or less equal cornuti whereas in M. aureata, the distal cornutus is broader while the lateral one is considerably shorter than in M. neoseriata. As the female of M. aureata is unknown, the female genitalia of M. neoseriata were compared with M. carcharias sp. nov. instead (see below in the diagnosis of the latter species).	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFBCFFA0FF0EFE32FDB8FAE4.taxon	diagnosis	Diagnosis. The forewing length is 9.0 mm in males. Miltochrista gopaldhara sp. nov. is most morphologically similar to M. neoseriata, from which it is distinguished by the smaller size and the narrower forewing apex. In the male genital capsule, the new species is distinguished from M. neoseriata in the longer uncus and the considerably shorter distal costal process. The male genital capsule of M. gopaldhara sp. nov. is also reminiscent of M. aureata but differs in the proximally broader uncus, and the narrower valva with a more medially convex dorsal margin. The vesica of M. gopaldhara sp. nov. is markedly broader and more globular than in M. neoseriata (it is rather sack-like in the latter), and the lateral cornutus sits on the shorter and narrower diverticulum situated on the right side of the vesica (vs. the left side in the congener). Compared to M. aureata, the vesica of the new species is slightly narrower and bears almost equal cornuti, whereas in M. aureata the distal cornutus is broader while the lateral one is considerably shorter than in M. gopaldhara sp. nov. The female is unknown.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFBEFFA2FF0EFF5BFD29FC04.taxon	diagnosis	Diagnosis. The forewing length is 10.0 – 10.5 mm in males. Miltochrista mawphlang sp. nov. is superficially reminiscent of M. neoseriata but distinguished by the smaller size, the less sinuous medial line, and the position of the discal spot, which is somewhat more distant from the medial line. In the male genitalia, the new species differs from M. neoseriata in the shorter uncus, the less prominent collis, the distally thinner and somewhat longer distal saccular process, and the shorter cornuti in the phallus vesica. The male genitalia structure of M. mawphlang sp. nov. is similar to the superficially different M. kravchenkoi (Figs 11, 12) recently described from north-western Myanmar (Volynkin et al. 2022 c). In the male genital capsule, the new species differs from the aforementioned congener (Fig. 102) in the markedly shorter and medially narrower uncus, the somewhat more medially convex dorsal margin of the valva, and the considerably shorter distal narrow section of the distal saccular process. The phalli of the two species are alike. The vesica of M. mawphlang sp. nov. is shorter and narrower than in M. kravchenkoi and bears a somewhat larger lateral cornutus.

BB06B339FFB0FFACFF0EFE5EFE9CF83B.taxon	discussion	Notes. (1) The species was synonymised with M. dharma by Hampson (1900) but subsequently revived to subspecies level by Inoue (1982). However, it displays clear differences in the genitalia of both sexes from the Himalayan M. dharma and therefore is upgraded herein to species level. (2) Leech ([1889] 1888) described the species based on a couple from Nagasaki and a male from “ Japan ” without exact locality data, of which only a female syntype from Nagasaki was located in the NHMUK collection. In order to stabilise the nomenclature, the aforementioned specimen is hereby designated as the lectotype.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFB0FFACFF0EFE5EFE9CF83B.taxon	diagnosis	Diagnosis. The forewing length is 9.5 – 10.5 mm in males and 11.0 – 11.5 mm in females. Miltochrista butleri is reminiscent of M. dharma but differs in the thinner forewing markings. The male genital capsule of the species is distinguished from M. dharma by the shorter uncus, the proximally narrower but distally broader valva with a less convex dorsal margin, the considerably longer distal costal process, and the markedly longer and upcurved distal saccular process (whereas it is straight in the congener). The phallus of M. butleri is broader than in M. dharma and having a larger coecum. Compared to M. dharma, the vesica of M. butleri is broader and having a lateral subbasal diverticulum (absent in the congener), and a markedly longer and broader medial diverticulum bearing a markedly larger blade-like cornutus and directed dorsally whereas in M. dharma, the medial diverticulum is directed distally. Additionally, the distal cornutus positioned at the base of the vesica ejaculatorius is considerably longer and broader in M. butleri in comparison to M. dharma. The male genitalia of M. butleri are most similar to the superficially dissimilar M. parallelinaformis (Figs 24, 106) but the genital capsule differs from the latter in somewhat shorter and narrower uncus, the medially narrower valva with a distally thinner distal costal process, and the longer and proximally narrower distal saccular process. The phallus of M. butleri is narrower and somewhat shorter than in M. parallelinaformis. Compared to M. parallelinaformis, the vesica of M. butleri has a considerably longer and broader medial diverticulum directed dorsally (it is directed distally in M. parallelinaformis), and a narrower cornutus on the distal diverticulum. As the female of M. parallelinaformis is unknown, the female genitalia of M. butleri were compared only to M. dharma, from which they are distinguished by the considerably shorter antrum, the markedly longer and broader corpus bursae with a longer posterior sclerotised area forming a prominent sclerotised lateral protrusion and inwardly edged with a longer cluster of markedly longer spines, and the presence of the postero-lateral cluster of robust spinules. Additionally, in M. butleri, the lateral sclerotised plates of the 7 th sternite bearing scales of the corethrogyne are significantly longer than in M. dharma, and their lateral sclerotised pockets are large and heavily sclerotised whereas they are reduced in the congener.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFB2FFAEFF0EFF5BFEBBFABF.taxon	diagnosis	Diagnosis. The forewing length is 11.0 – 11.5 mm in males and 12.0 mm in the female. Among the Himalayan species of the genus, M. carcharias sp. nov. is superficially reminiscent of M. neoseriata, M. gopaldhara sp. nov. and M. nuranang sp. nov. but distinguished from them by the more distally convex forewing costal margin, the thinner and more diffuse pattern elements, and the presence of the intense grey suffusion between the longitudinal streaks in the postmedial area (the latter is also present in some specimens of M. nuranang sp. nov. but it is markedly more diffuse). Additionally, compared to M. nuranang sp. nov., the new species has shorter longitudinal streaks in the forewing antemedial area. The male genital capsule of M. carcharias sp. nov. is largely different from other species in the group in the strongly dilated, triangular distal costal process directed dorsally whereas it is elongate, slender and distally directed or downcurved in the similar congeners. The phallus and the vesica shape of the new species are most similar to M. dharma but in M. carcharias sp. nov., the phallus is broader, and having a noticeably broader and longer coecum and a well-developed carinal crest. In the vesica, M. carcharias sp. nov. is distinguished from M. dharma by the presence of the apical diverticulum (at the base of the vesica ejaculatorius) and the distal cornutus situated more laterally. The female genitalia of the new species differ clearly from M. dharma in the markedly shorter and anteriorly tapered antrum (it has almost parallel margins in M. dharma), the considerably shorter and narrower corpus bursae with a shorter sclerotised posterior area and weaker spinulose scobination anteriorly. In the female genitalia, M. carcharias sp. nov. is most similar to M. neoseriata, from which, however, the new species is distinguished by the markedly smaller corpus bursae lacking the posterior elongate clusters of the robust spines. Additionally, the lateral pockets of the 7 th sternite of M. carcharias sp. nov. are considerably shorter and more weakly sclerotised than in M. neoseriata.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

The species displays no remarkable superficial differences from M. neoseriata and the identification requires the examination of the genitalia structures which are largely different in both sexes of these species. The male genital capsule of M. paraseriata is reminiscent of M. butleri but can be distinguished by the medially and distally broader valva with a more convex dorsal margin, the longer and more downcurved distal costal process, and the somewhat shorter and apically rounded distal saccular process which is apically pointed in the congener. The phallus of M. paraseriata is narrower than in M. butleri and has a larger ventral carinal crest. The vesica of the current species is markedly broader than in M. butleri, lacks a subbasal diverticulum and has a considerably broader medial diverticulum bearing a shorter and proximally broader cornutus.

BB06B339FFB4FFA8FF0EFDA6FD5EF8C0.taxon	diagnosis	Diagnosis. The forewing length is 7.5 – 9.5 mm in males and 10.0 mm in females. Miltochrista ephimeces sp. nov. is superficially very similar to M. paraseriata and reliable identification requires examination of the genitalia structures which are largely different in both sexes of these species (e. g., the shape of the uncus and distal saccular process and the vesica configuration). The male genital capsule of the new species is similar to those of the superficially dissimilar M. simonka (Figs 35, 36, 112) and M. flavorosea (Figs 37 – 39, 113), and differs from the former species in the proximally slender uncus (it is proximally dilated in the congener) and the proximally broader distal costal process. Compared to M. flavorosea, the male genital capsule of M. ephimeces sp. nov. has a considerably longer uncus, a proximally broader distal costal process, and a somewhat shorter distal saccular process. The phallus of the new species is similar to that of M. simonka but is markedly shorter and more proximally dilated than in M. flavorosea. In the vesica configuration, M. ephimeces sp. nov. is similar to M. simonka but distinguished by the longer and markedly broader distal cornutus. In the female genitalia of the new species, the antrum is posteriorly narrower than in M. simonka but noticeably broader than in M. flavorosea. The corpus bursae of M. ephimeces sp. nov. bears clusters of markedly smaller spines posteriorly in comparison to the aforementioned congeners (Figs 140, 141). The appendix bursae of M. ephimeces sp. nov. is narrower and more elongated than in the aforementioned congeners. Additionally, the lateral sclerotised plates of the 7 th sternite of the new species are longer than in M. simonka and more rugose than in M. flavorosea, and their lateral pockets are narrower and more triangular than in those congeners.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFB7FFABFF0EFF5BFD0AFAA3.taxon	diagnosis	Diagnosis. The forewing length is 13.0 mm in males and 14.5 mm in females. Miltochrista discistriga is similar to M. neoseriata in its forewing markings but distinguished by its larger size. The male genital capsule of the species is clearly different from other similar congeners in the shorter uncus, the relatively short and claw-shaped, and dorsally directed distal costal process, the broad valvula, and the narrow but heavily sclerotised and upcurved distal saccular process. The vesica structure of M. discistriga is similar to those of such species as M. neoseriata, M. aureata, M. mawphlang sp. nov. and M. kravchenkoi but differs in the markedly longer cornuti. The female genitalia of M. discistriga are most reminiscent of M. neoseriata but are distinct due to the shorter and narrower ductus bursae with a sinuous ventral margin of the ostium, and the broader corpus bursae with a narrower but more heavily sclerotised postero-lateral sclerotised area edged with smaller spines and lacking a cluster of denticles at the junction with the ductus bursae. Additionally, the lateral sclerotised plates of the 7 th sternite of M. discistriga are shorter and more weakly sclerotised than in M. neoseriata, and their lateral pockets are vestigial.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFA9FFB5FF0EFF5BFE9FFAB7.taxon	diagnosis	Diagnosis. The forewing length is 10.0 – 10.5 mm in males and 12.0 mm in females. Miltochrista jatinga sp. nov. is superficially reminiscent of M. neoseriata but can be distinguished from it by the thicker longitudinal streaks and the medial line of the forewing, and the larger discal spot. However, in the genitalia of both sexes, the new species is similar to the partially sympatric M. zinchenkoi (Figs 51 – 53), from which M. jatinga sp. nov. is superficially differs in the narrower forewing, the longer longitudinal streaks in the ante- and postmedial areas, the oblique and less posteriorly curved medial line which is medially almost perpendicular the forewing axis in M. zinchenkoi, and the smaller discal spot well-separated from the medial line (it is almost touching the line in the congener). In the male genital capsule, M. jatinga sp. nov. is distinguished from M. zinchenkoi (Figs 118, 119) by the proximally narrower valva with a longer valvula, the triangular and apically pointed distal costal process (it is rounded in the congener), and the smoothly upcurved distal saccular process whereas it is upcurved at an almost right angle in M. zinchenkoi. In the phallus, the new species has a more downcurved coecum in comparison to the similar congener. The vesicae of the two species are similar but in M. jatinga sp. nov., the subapical cornutus is slightly thinner than in M. zinchenkoi. The female genitalia of the new species differ from M. zinchenkoi (Fig. 144) in the anteriorly broader ductus bursae, and the broader corpus bursae bearing thinner and more numerous spines along the inner margin of the postero-lateral sclerotised plate. Additionally, the lateral pockets of the 7 th sternite of the new species are broader than in M. zinchenkoi and are apically almost semicircular whereas they are bearing narrow triangular protrusions in the aforementioned congener.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

The male genitalia of the species-group are characterised by the relatively short, laterally flattened and medially dilated uncus, and the costa lacking an elongate and slender distal process typical of the M. humilis species-group. Instead of the latter, in most species of the group, the costa is distally dilated and bears a ventrally directed apical process in certain taxa. Only in M. floccosa the costa is gradually distally tapered and dorsally fused with the valvula.

BB06B339FFA8FFB6FF0EFE7AFBB5FD18.taxon	discussion	Notes. (1) Walker ([1865]) described Nudaria floccosa from a single specimen (lettered as ‘ a’), which is a holotype by monotypy. Walker ([1865]) identified the sex of the holotype as male but the specimen is in fact a female (Fig. 54). (2) Walker ([1865]) described Nudaria subcervina based on the unspecified number of males from Atkinson collection from “ Hindostan ”. This taxon was subsequently synonymised with M. floccosa without explanation by Hampson (1900). Not a single syntype specimen was found either in the NHMUK, OUMNH or MfN collections, where Walker’s types and specimens from Atkinson collection are housed, therefore it is possible to conclude that the type material is lost. Fortunately, in the unpresorted accessions in the NHMUK collection, a male specimen identified as “ Miltochrista subcervina ”, originating from eastern India and matching the original Walker’s description was found. In order to stabilise the nomenclature, this specimen is hereby designated as the neotype, and, according to the ICZN (1999) Article 76.3, the type locality is hereby determined by the neotype designation. Despite the external differences, the male genitalia of the neotype of M. subcervina display no distinctive characters from the polymorphic M. floccosa proving the conspecificity of these two taxa. Thus, the synonymy of subcervina with floccosa originally introduced by Hampson (1900) is herein confirmed: M. floccosa = Nudaria subcervina, syn. rev. (3) Unfortunately, we had no chance to examine the holotype (by monotypy) of Asura violacea, which should be in Paul Reich collection currently preserved in the Steinhardt Museum of Natural History, Tel Aviv, Israel. However, the detailed description of the taxon provided by Reich (1936) fully corresponds to M. floccosa widely distributed from the western Himalayas to Sri Lanka and therefore Asura violacea is herein synonymised with it.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFA8FFB6FF0EFE7AFBB5FD18.taxon	diagnosis	Diagnosis. The forewing length is 8.0 – 10.0 mm in males and 10.0 mm in females. The species varies in its size and the shape of the postmedial fascia but the genitalia structures display only limited variability in the uncus width and the shape of the valva apex. Miltochrista floccosa is superficially most reminiscent of M. ochracea (Figs 62, 63) endemic to South India but can be easily distinguished by its considerably smaller size, bipectinate male antenna (it is ciliate in M. ochracea), and the more diffuse forewing markings. The male genital capsule of M. floccosa differs from M. ochracea (Fig. 122) in the considerably shorter uncus, the shorter tegumen with broader arms, the less elongate valva lacking the distal costal process (it is well-developed, triangular and directed ventrally in the congener), and the markedly longer distal saccular process. The phallus of M. floccosa is proximally broader than in M. ochracea and has a more distally prominent carinal crest. Compared to M. ochracea, the vesica of M. floccosa is significantly broader (in proportion to the phallus size), having a subbasal dorsal diverticulum, and bearing a robust cornutus whereas M. ochracea has two considerably shorter and narrower cornuti. In the female genitalia, M. floccosa is distinguished from M. ochracea (Fig. 146) in the more caliciform ventral margin of the antrum, the markedly broader postero-lateral sclerotised plate of the corpus bursae edged with considerably shorter and thinner spines, the shorter and narrower anterior section of the corpus bursae, the presence of the short conical lateral protrusion of the corpus bursae, and the sack-like appendix bursae whereas it is conical in the congener.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFAAFFB0FF0EF90AFAE9FB01.taxon	discussion	Notes. (1) Moore (1878) described the species from the unspecified number of males. Subsequently Hampson (1900) cited only one male specimen as “ Type ”, which is a valid lectotype designation, according to the Article 74.5 of ICZN (1999). (2) The species greatly varies in its size, forewing width and the forewing pattern elements. In the male genitalia, the size of the medial process of the uncus, the size and shape of the lateral processes of the tegumen, the length of the distal costal process, and the length and width of the cornuti are also variable.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFAAFFB0FF0EF90AFAE9FB01.taxon	diagnosis	Diagnosis. The forewing length is 9.0 – 10.5 mm in males and 10.0 – 11.5 mm in females. Miltochrista terminata is superficially largely reminiscent of M. neoseriata and M. nuranang sp. nov. and the reliable identification requires the examination of the genitalia structures. In the male genital capsule, M. terminata is distinguished from M. nuranang sp. nov. by the apically pointed subuncal lobes, and the presence of triangular lateral processes of the tegumen. The phallus of M. terminata is medially upcurved whereas it is almost straight in the similar congener, and the vesica is somewhat broader. The female genitalia of M. terminata differ clearly from M. nuranang sp. nov. in the considerably shorter antrum with a basally narrower but markedly longer ventral crest, the slightly narrower postero-lateral subostial lobes, and the corpus bursae lacking the postero-lateral sclerotised protrusion.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

Compared to M. vidlickai, the phallus of the new species is shorter, markedly narrower (in proportion to the genitalia capsule size), and almost straight whereas it is medially upcurved in the congener. In the vesica of M. nuranang sp. nov., both the cornuti are shorter than in M. vidlickai. The female genitalia of M. nuranang sp. nov. differ from M. vidlickai by the considerably longer antrum bearing a basally broader but markedly shorter ventral crest, and the shorter corpus bursae. Additionally, the lateral pockets of the 7 th abdominal sternite of the new species are longer than in the similar congener.

BB06B339FFA1FFBDFF0EFE32FBBEF93F.taxon	diagnosis	Diagnosis. The forewing length is 6.5 – 7.5 mm in males and 7.0 – 8.0 mm in females. Miltochrista andamana is readily distinct from the other members of the species-group due to its ochreous forewing ground colour (it is yellow in the related congeners), the medial line medially convex outwards, and the shorter dashes of the postmedial line touching each other. The male genital capsule of the species is similar to M. quadrata but is distinguished by the considerably shorter and medially narrower uncus, the longer vinculum, and the somewhat broader valva with a shorter and narrower distal section of the valva having a more rounded dorsal corner. The phallus of M. andamana is shorter and narrower than in the similar congener, and with a markedly more elongate, thumb-shaped coecum. Compared to M. quadrata, the vesica of the current species is broader (in proportion to the genital capsule size), having a narrower and conical terminal diverticulum (it is semiglobular in the congener), and bearing three cornuti (vs. two cornuti in M. quadrata). In the female genitalia, M. andamana differs from M. quadrata in the somewhat shorter antrum, and the smaller spines in the posterior clusters in the corpus bursae.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFA1FFBFFF0EF8EBFDFBFC05.taxon	diagnosis	Diagnosis. The forewing length is 7.0 – 8.0 mm in both sexes. The species is variable in its size and the degree of the expression of the forewing markings (demonstrated by Bucsek (2012 )). Miltochrista quadrata is superficially reminiscent of a number of taxa in the M. strigipennis species-group, viz. M. circumdata, M. corrigera, M. cumseriata, M. pectena (illustrated by Bucsek 2012), and M. poring (illustrated by Holloway (2001 )), and the reliable identification requires the examination of the genitalia structures. The male genitalia of the species are characterised by the relatively broad and rectangular distal section of the valva and the strongly medially dilated uncus. The detailed comparison of the genitalia of both sexes of M. quadrata with M. andamana is provided above in the diagnosis of the latter species.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

BB06B339FFA3FFBFFF0EFBF2FBE0F81C.taxon	diagnosis	Diagnosis. The forewing length is 8.5 – 11.0 mm in males and 10.0 – 11.5 mm in females. Although significantly variable in size, M. producta is easily distinguishable from the other congeners by the oblique, dash-shaped discal spot of the forewing and the medially angled medial transverse line. The male genital capsule of M. producta readily differs from the other species in the species-group by the proximally dilated and bilobate distal saccular process which is slender and unilobate in the similar congeners. The phallus and the vesica of M. producta are reminiscent of those of M. andamana but the phallus of the current species is longer and broader, and the vesica is markedly broader and two distal of its three cornuti are considerably shorter and narrower than the proximal one whereas the corresponding cornuti of M. andamana are only slightly shorter and narrower than the proximal one. The female genitalia of M. producta differ from the other taxa in the species-group by the shorter antrum (in proportion to the ovipositor length), and the more elongate corpus bursae bearing smaller spines posteriorly and covered with more robust spinules anteriorly.	en	Volynkin, Anton V., Singh, Santosh, Černý, Karel, Kirti, Jagbir Singh, Datta, Harvinder Singh, Singh, Navneet (2025): On the taxonomy of the genus Miltochrista Hübner with descriptions of six new species from the Oriental Realm (Lepidoptera: Erebidae: Arctiinae: Lithosiini).
