6. Forewing greyish brown with diffuse pale area in basal 2/5 ( Fig. 31 ); tergites II–V with microtrichia at middle of posterior margin (Fig. 8), tergites IX and X sub-equal in length (Fig 11–12); males with pore plates on sternites III– VIII ( Fig. 6 ) .............................................................................................................................................. pilarae sp.n.

-. Forewing uniformly brown except a subasal small white fleck ( Fig. 32 ); tergites II–V without microtrichia at middle of posterior margin (Figs19–20); tergite X much shorter than tergite IX (Figs 22–23); males with pore plates only on sternites VI–VIII ( Fig. 17 ) ......................................................................................................................... stellae sp.n.
