Yashmakia bigrisea sp. n.  

Yashmakia bigrisea (paratype)

16mm. The species resembles a large Y. suffusa but is distinguished externally by the broad grey postmedial of the forewing, oblique over the dorsal half and strongly curved round the discal spot anteriorly. This is edged distad by a much darker, diffuse, narrower band, and straight bars of the same dark colour occur across the forewing tornus, connecting the postmedial band to the margin apically and centrally, and, on the hindwing, subbasally and from apex to tornus. The uncus and valves are typical of the genus, though the latter are narrow, the costa with a slight excavated process at one third. The aedeagus vesica bears a single row of numerous very long cornuti.
