Barsine pseudoradians Joshi, Singh & Volynkin, 2018 , Zootaxa, 4425 (3): 457, figs 1–4, 23, 24, 34 (Type locality: “NE India, Assam, Nameri Nat. Park, 40 km N Tezpur, 150 m ”).

Type material examined. Holotype ( Figs 21 , 159 ): ♂, NE India, Assam, Nameri Nat. Park , 40 km N Tezpur, 150 m, 27°20’N, 93°15’E, 24.VII–2.VIII.1997, leg. Sinjaev & Murzin, slide MWM 33559 Volynkin (Coll. MWM/ ZSM) ; Paratypes: 16 ♂ and 23 ♀ from India and Nepal listed by Joshi et al. (2018) (Colls MWM/ ZSM and NZCZSI) .

Diagnosis. Forewing length is 10–12 mm in both sexes. Barsine pseudoradians is similar externally to B. radians , but differs by its slightly smaller size, discal spot of forewing situated slightly more posteriorly (especially in female), reduced postmedial line in male, and slightly narrower outer field of forewing. The male genitalia of B. pseudoradians differ from those of B. radians by their much broader, shield-like juxta (that is smaller and pentagonal in B. radians ), distally broader valva, much narrower medial costal process, slightly longer and apically pointed distal costal process, much longer distal saccular process, the absence of a spinulose field on aedeagus carina, more robust cornuti, and the presence of two additional small diverticula with strong granulation in vesica. The female genitalia of B. pseudoradians differ from those of B. radians by their much broader ostium bursae, broader postvaginal plate, ductus bursae being shorter, narrower and membranous, stronger spinulose scobination of corpus bursae, larger signum, and appendix bursae directed anteriorly.

Distribution. Nepal and North-East India (Assam, Meghalaya and Mizoram) ( Joshi et al. 2018).
