Cyana abrupta Volynkin & Černý, 2019 , Ecologica Montenegrina 21: 59, Figs 5, 6 , 15, 18 (Type locality: “NE India, Assam, Pan Bari Reserv Forest”).

Type material examined. Holotype: ♂, “NE India, Assam, Pan Bari Reserv [e] Forest , 27°08’N, 94°00’E, 4– 7.VII.1997, leg. Sinjaev & Murzin”, slide MWM 31805 Volynkin (Coll. MWM / ZSM).

Paratypes: 30 ♂ and 21 ♀ from India, Nepal and Bangladesh listed by Volynkin & Černý (2019) .

Diagnosis. Forewing length is 14–16 mm in males and 17–19 mm in females. Cyana abrupta has no significant external differences from its closest relatives, C. indosinica Volynkin & Černý, 2018 and C. malayana Bucsek, 2012 (illustrated by Volynkin et al. 2018). The male genitalia of C. abrupta differ from those of C. indosinica by their trigonal lateral lobes of the vinculum (whereas in C. indosinica and other related species the lobes are more rounded), the much shorter and narrower medial posterior, medial anterior and distal diverticula, and the narrower medial dorsal diverticulum. The female genitalia differ from those of other related species (illustrated by Volynkin et al. 2017) by the shorter ductus bursae, the long, narrow and weakly rugose posterior sclerotized plate of the corpus bursae, the heavily sclerotized lateral band-like signum, and the significantly larger anterior signum.

Distribution. Nepal ( Kishida 1994, as bianca ), North and North East India (Himachal Pradesh, Sikkim, Arunachal Pradesh, Assam, Meghalaya) (Kirti et al. 2013, as bianca ), Bangladesh (Volynkin et al. 2018 (as C. bianca ); Volynkin & Černý 2019b).
