Ovipennis Hampson, 1900 View in CoL , Catalogue of Lepidoptera Phalaenae in the British Museum 2: 410 (Type species:

Nudaria dudgeoni Elwes, 1890 View in CoL , by original designation).

Diagnosis. Small moths with diverse colouration and pattern. The male genitalia are similar to those of Ammatho (especially, the subgenus Striatella ), but in Ovipennis aedeagus vesica has elongated diverticula with bunches of spinules, whereas in Ammatho vesici bear clusters of numerous small cornuti or separated large conical cornuti. Medial costal process is usually well developed, but reduced (up to absence) in the subgenus Coccinigripennis . Female genitalia are characterised by (1) the evenly sclerotised ductus bursae (in Ammatho that is separated into antrum and membranous anterior section) and (2) the presence of rows of robust spinules or heavily sclerotised plates which may be dentate (absent in Ammatho ).

Distribution. The genus is widespread from South India through Himalaya to China and northern Indochina.

Subgenus Ovipennis Hampson, 1900 ( Figs 21, 22 View Figures 17–30 , 115 View Figures 112–115 , 170 View Figures 166–173 )

Diagnosis. Small moths with pattern expressed as large spots and longitudinal stripes. The male genital capsule is very similar to that of Ammatho (Striatella) , but distal costal process is lobe-like broadened, whereas in Ammatho (Striatella) that is thorn-like. In some species aedeagus carina bears a small cluster of small but robust spinules. Aedeagus vesica with elongated diverticula bearing bunches of large spine-like cornuti. Female genitalia are similar to those of Miltochrista , with the posterior section of corpus bursae bearing clusters of numerous robust spine-like cornuti posteriorly.

Distribution. The subgenus is distributed from Himalaya through northern Myanmar to southern China and northern Indochina.

Number of species. The nominate subgenus comprises seven valid species.

Subgenus Barsipennis Volynkin , subgen. nov. https://zoobank.org/ urn:lsid:zoobank.org:act:2EC2C0E7-8CD0-4DC7-91C0-25BDE20C701B ( Figs 23, 24 View Figures 17–30 , 116 View Figures 116–119 , 171, 172 View Figures 166–173 )

Type species: Barsine joshii Volynkin & Černý, 2019.

Etymology. The subgenus name is a combination of the generic names Barsine and Ovipennis . Gender feminine.

Diagnosis. Small moths with yellow colouration and black ‘miltochristoid’ pattern. The male genital capsule is similar to that of the nominate subspecies, but distal costal process is developed as a very short rounded protrusion ( O. phaeodonta , O. joshii and O. meyi ) or absent ( O. mophi and O. arrigera ). The aedeagus vesica structure is similar to that of the nominate subspecies, but diverticula bear bunches of spinules and not spine-like cornuti. Female genitalia are characterised by the presence of sclerotised plates in corpus bursae which may be dentate.

Distribution. The subgenus is distributed from Himalaya through northern Myanmar to northern Indochina.

Number of species. The subgenus comprises five valid species reviewed by Volynkin & Černý (2019a) as ‘the Barsine phaeodonta species-group’.

Subgenus Nebulene Volynkin & Černý, 2018, stat. nov. ( Figs 25, 26 View Figures 17–30 , 117 View Figures 116–119 , 174 View Figures 174–181 )

Nebulene Volynkin & Černý, 2018, Zootaxa 4394 (2): 220 (Type species: Setina nebulosa Moore, 1878 , by original designation).

Diagnosis. Small moths, the male antennae are bipectinate, the female antennae are finely ciliate. Forewing pattern consists of a trigonal antemedial and broad postmedial shades connected at dorsum, a wavy and thin medial line, and a discal spot. The male genital capsule is very similar to that of Barsipennis , but the medial costal process is more robust. In aedeagus vesica bears one–two large, well separated blade-like cornuti, whereas in Barsipennis patches of spinules are present only. Such a robust medial costal process and large blade-like cornuti are present in male genitalia of several other genera of the Asura / Miltochrista generic complex, but never in combination as in Nebulene . The male genitalia of Nebulene also resemble those of Barsura , but differ by the absence of a distal costal process, absence of a carinal plate, and presence of well separated, long, narrow, but robust cornuti. In the female genitalia of Nebulene the ductus bursae is weakly membranous, a feature also found in the Asura / Miltochrista generic complex in the genus Barsochrista only. Nevertheless, in Nebulene the appendix bursae is situated postero-laterally and the posterior section of corpus bursae bears heavily sclerotised and dentate plates. The latter feature is also occurring in the subgenus Barsipennis only.

Distribution. The genus is distributed in Himalaya, southwestern China and Indochina.

Number of species. The genus comprises two valid species reviewed by Volynkin & Černý (2018c).

Subgenus Coccinigripennis Volynkin & Huang , subgen. nov. https://zoobank.org/ urn:lsid:zoobank.org:act:6D3F1640-01E9-40D3-B0C1-B1B3C3C8CE85 ( Figs 27, 28 View Figures 17–30 , 118 View Figures 116–119 , 173 View Figures 166–173 )

Type species: Barsine incompletostriga Volynkin & Cerny, 2017.

Etymology. The subgenus name is a combination of the Latin word ‘coccinigrum’ meaning ‘crimson and black’ and the generic name Ovipennis . Gender feminine.

Diagnosis. Small moths with outwardly rounded forewing having crimson ground colour and black pattern represented as a longitudinal strip or a broad shade. In male genital capsule, valva is elongated, with setose sacculus and small distal costal process. The subgenus differs from other subgenera by its medial costal process reduced to a small tubercle or denticle (the O. anomala , O. fansipana and a part of O. miloslavae species-groups) or absent (most species of the miloslavae species-group). Female genitalia of the subgenus are characterised by the presence of band-like clusters of numerous short but robust spinules (except for O. anomala and O. fansipana having corpus bursae evenly covered with numerous spinules). Signum bursae is present in all species.

Distribution. The subgenus is distributed from Himalaya through northern Myanmar to southern China and northern Indochina.

Number of species. The subgenus comprises six valid species reviewed by Volynkin & Černý (2017b) as the ‘ Barsine anomala ’, ‘ Barsine fansipana ’ and ‘ Barsine miloslavae ’ species- groups.
