( Figs 39–41 , 170, 171 , 235 )

Barsine wernerthomasi Volynkin, 2018 , Far Eastern Entomologist, 358: 7, figs 9–11, 25, 26, 37 (Type locality: “ India, Sikkim, Namchi, 1000 m ”).

Type material examined. Holotype ( Figs 39 , 170 ): ♂, India, Sikkim, Namchi , 1000 m, 2.VII 1986, leg. W. Thomas, slide MWM 31791 Volynkin (Coll. MWM/ ZSM) . Paratypes: 2 ♀, same data as in the holotype, slide MWM 31792 (♀) Volynkin ( Coll. MWM/ ZSM) ; 1 ♂, 1 ♀, Gopaldhara, June 1918 (Stevens) / Rothschild bequest 1939.-I. ( Coll. NHMUK) ; 1 ♀, Sikkim (H. Stevens) / Rothschild bequest 1939.-I. ( Coll. NHMUK) ; 1 ♂, 1 ♀, Sikkim (H. Stevens), slides AV1916 ♂, AV1917 ♀ Volynkin ( Coll. ZFMK) ; 6 ♂, 1 ♀, East Nepal, Kanchenjunga Himal, Khambachen , 4150 m, 28.VI.1998, leg. Márton Hreblay & Balázs Benedek, slide MWM 33576 (♂) Volynkin ( Coll. MWM/ ZSM) .

Diagnosis. Forewing length 15–17 mm, in males and 17–18 mm in females. Barsine wernerthomasi differs from B. prominens by its much larger size and shorter blackish marginal stripes on veins of hindwings; wernerthomasi differs from B. paraprominens by its medial line being not connected to the antemedial line and the antemedial line angled in the cell and interrupted (while that is evenly curved and not interrupted in B. paraprominens ). In the male genitalia, B. wernerthomasi differs from those of B. prominens by its distally broader valva with slightly longer distal section between the apical costal process and the valva apex, slightly weaker medial costal process, thinner and apically pointed distal saccular process, the presence of robust granulation in the distal diverticulum of vesica (that has a broad cluster of cornuti in B. prominens ), and weaker granulation of lateral diverticula of vesica; in comparison to those of B. paraprominens , the male genitalia of B. wernerthomasi differ by their thinner tip of the distal saccular process, and the presence of robust granulation in the distal diverticulum of vesica (that has a broad cluster of cornuti in B. paraprominens ). In the female genitalia, B. wernerthomasi differs from B. prominens by its postero-lateral sclerotized field of corpus bursae being much larger and heavily sclerotized, and the much weaker spinulose scobination of corpus bursae.

Distribution. North-East India (north of West Bengal, Sikkim) and East Nepal (Volynkin 2018).
