( Figs 10–12 , 154 , 224 )

Barsine pluma Černý, in Černý & Pinratana, 2009 , Moths of Thailand 6: 73–74, pl. 16, fig. 146, pl. Genitalia 1, figs. T146f, T146v (Type locality: “W. Thailand, 400 m, Uthai Thani Prov., Khao Nang Rum”).

Type material examined. Holotype ( Fig. 11 ): ♀, “W. Thailand: 400 m, Uthai Thani Prov., Khao Nang Rum , 17–18.XI.1985, M.G. Allen [leg.], BM 1986-74” (Coll. NHMUK) . Paratypes: 34 ♂ and 15 ♀ from West , North and Central Thailand listed by Volynkin & Černý (2018b) (Coll. CKC) .

Other material examined. 48 ♂ and 8 ♀ from Thailand and Laos listed by Volynkin & Černý (2018b) (Colls MWM/ ZSM, CKC) .

Diagnosis. Forewing length is 10–11 mm in males and 11–12 mm in females. Barsine pluma is similar externally to B. zebrina occurring in Thailand sympatrically with it, but differs by its not interrupted medial line. The male genitalia of B. pluma differ from those of B. zebrina by their much larger medial costal process, weaker distal costal process, narrower basal lobe of sacculus having smoothly curved dorsal margin, and much longer distal saccular process with pointed apex. The female genitalia of B. pluma are very similar to those of B. zebrina , but differ by their broader, T-shaped postvaginal plate (that is narrower and V-shaped in B. zebrina ), and slightly smaller signum. The genital differences from B. bucseki are listed in the diagnosis of the latter.

Distribution. Thailand (Uthai Thani, Tak, Kanchanaburi, Lampang, Chiang Mai, Mae Hong Son, Phayao, Nan, Phetchabun, Sakhon Nakhon, Ubon Ratchatani), Laos (Phongsali, Luang Prabang, Xayaburi, Vientiane and Khammouan) ( Volynkin & Černý 2018b).
