 Jowls black-haired. Occiput grey, black-haired, with pale liairs on 

 middle part and below; two rather distinct rows of black hairs behind 

 postocular bristles. Antennæ with third joint only a little longer 

 than second, at most one and a half times as long, but reaching

 lateral black stripes broader than the middle, this latter as broad

 cleft to middle, in profile with about 

 parallel margins, the dorsal bending evenly 

 forwards to the pointed apex, the ventral

 with long hairs on upper part, apical part bare. Anterior claspers 

 longer than posterior, with the end bent and obtuse, the posterior 

 claw-shaped and pointed. Penis with the end part slightly chitinised, 

 pale, not bent forwards, it is forked and thus divided into two pointed

 slightly chitinised, and below them two pairs of rod-like apophyses 

 Crossing each other, the distal roundish dilated at apex, the proximal 

 a little serrated on ventral side. Posterior femora fringed below; 

 hind tibiæ fringed on posteroventral side, but only short-haired 

 antero ventrally; middle tibiæ not fringed; middle femora with a

 bristles. Wings with costal segment 3 longer than 5; subcostal vein
