Barsine zebrina ( Moore, 1878)

( Figs 4–6 , 152 , 222 )

Lyclene zebrina Moore, 1878 , Proceedings of the Scientific Meetings of the Zoological Society of London, 1878: 31, pl. III, fig. 4 (Type locality: “Calcutta District”).

Type material examined. Holotype ( Fig. 4 ): ♀, handwritten label “Calcutta” (upperside) Lyclene zebrina ♂ (type) Moore” (underside) / printed label “Moore Coll. 94–106” / round printed label with red circle “Type” / printed label with QR-code “NHMUK010604417” (Coll. NHMUK).

Other material examined. 24 ♂ and 8 ♀ from NE India and Thailand listed by Volynkin & Černý (2018b) (Colls NHMUK, CKC and CAV) .

Diagnosis. The species significantly varies in size (forewing length is 9–10.5 mm in males and 9–12 mm in females), with forewing ground color from yellowish creamy to whitish. Externally, B. zebrina is similar to B. subzebrina , and can be separated by the genitalia structures. The male genitalia of B. zebrina are similar to those of B. subzebrina , but differ by their smaller medial costal process, broader distal costal process with a much shorter (sometimes absent) apico-lateral projection (that is narrower and has a much longer apico-lateral projection in B. subzebrina ), and larger basal lobe of sacculus, which is trigonal and armed with smaller dens (in B. subzebrina , that is broader with evenly curved dorsal margin armed with larger dens). The female genitalia of B. zebrina differ from those of B. subzebrina by their broader, T-shaped postvaginal plate and antrum without a concavity.

Distribution. North-East India (West Bengal, Mizoram) ( Kirti & Singh 2016, as pluma ), West and North Thailand (Kanchanaburi, Tak, Chiang Mai, Phrae and Nan) ( Volynkin & Černý 2018b).
