description: Barsine joshii Volynkin & Černý, sp. nov.   
(Figs 5–8, 18, 26)  
 Type material. Holotype (Figs 5, 18): male, “NE- India, Assam, W. Meghalaya, Garo Hills, Nokrek National Park, 25°40"N, 91°04"E, 1150m, 2–13.VII.1997, leg. Afonin & Sinajev”, slide MWM 31457 Volynkin (Coll. MWM / ZSM).   
 Paratypes: 1 males, 14 females, same data as in the holotype, slides MWM 31419 (male), MWM 31420 (female) Volynkin (Coll. MWM / ZSM); 2 males, 4 females, India mer., Tamil Nadu, Kalkad, Wildlife Sanctuary Manjolai, 6–7.IV.[19]97, 8.15"N, 77.27"E, tea estate/rainforest, Sinjaev & Schintlmeister, slides ZSM Arct. 28/2017 ♂ and ZSM Arct. 29/2017 ♀ Volynkin (Coll. MWM / ZSM); 1 female, Gopaldhara, Sikkim (H. Stevens) / Miltochrista phaeodonta Hampson det. A. Watson 1962 TOPOTYPE, slide AV1899 Volynkin (Coll. ZFMK).   
 Diagnosis. Forewing length is 10 mm in males (wingspan 20 mm) and 12–12.5 mm in females (wingspan 25–26 mm). Externally, B. joshii (Figs 5–8) can be distinguished from its closest relatives B. phaeodonta (Figs 1–4) and B. meyi (Figs 9, 10) by its thicker subbasal strokes, slightly thicker antemedial line, slightly thicker medial line being less curved and well separated from the antemedial line, dot-shaped discal spot (that is more or less comma-shaped in B. phaeodonta and B. meyi), more sharp postmedial line with shorter dens (in B. phaeodonta and B. meyi that is diffuse and has longer dens), larger subterminal spots on veins, and weaker dark suffusion on hindwing. The male genitalia of B. joshii (Fig. 18) differ clearly from those of B. phaeodonta (Fig. 17) and B. meyi (Fig. 19) by their narrower vinculum, valva being narrower distally, robust medial costal process being hook-shaped (that is weaker and spine-shaped in B. phaeodonta and B. meyi), shorter distal saccular process directed dorsally (that is longer and directed distally-dorsally in B. phaeodonta and B. meyi), broader aedeagus, the robust and strongly dentate carinal plate (in B. phaeodonta and B. meyi that is present as a weakly dentate area), and broader diverticula of vesica bearing much broader bunches of more robust spinules. The female genitalia of B. joshii (Fig. 26) differ clearly from those of B. phaeodonta (Fig. 25) by their shorter apophyses anteriores, broader ostium bursae with narrower sclerotized margins, much broader ductus bursae, and the presence of two small areas of dentation in the posterior section of corpus bursae (whereas in B. phaeodonta there is a broad area of dentation, which encircles the posterior section of corpus bursae).   
 Distribution. South and North East India (Tamil Nadu, Meghalaya and Sikkim).   
 Etymology. The species is dedicated to Dr. Rahul Joshi (Kolkata, India), a famous expert in Indian Arctiinae.
