Syrastrenopsis bilinea Kishida, 1995

Figs 12–13

Syrastrenopsis bilinea Kishida, 1995 , Tinea 14 (Moths of Nepal Suppl. 2): 38, fig. 607, pl. 105, figs 3, 4. TL: Eastern Nepal, Kathmandu, Godavary, 1600 m. HT: female (NSMT) [examined].

Forewing dark yellowish-brown with darker external zone, medial fasciae dark reddish-brown without light shadows, external fascia absent. Hind wings with darker outer margin and two smooth transversal reddish-brown fasciae; fore tibia with short epiphysis.

In female genitalia both pairs of apophyses are of the same length, long and narrow; antevaginal plate weak, short, with few wrinkles.

Males unknown so far.

Diagnosis. The basic wing pattern is nearly the same as that of S. moltrechti and kawabei , but the ground color of both wings is paler brown and not tinged with red, the submarginal line of the forewing is absent, and the median fasciae of the hind wing is more prominent.

Differs from congeners by yellow saturated wings, absence of any light transversal fasciae, patterned hind wings and having the smallest epiphysis. Genitalic characters including the small antevaginal plate should confirm the identification.

Bionomics. Believed to be univoltine, with flight period in late August to early December; is known from 1500–1600 m. Females attracted to the light. Preimaginal stages still unknown
