Figures 1 , 2 , 3 Description. Head (Fig. 1A ) yellowish brown, base of crown with some darker brown marking, ocelli reddish brown. Thorax sordid brown; forewings (Fig. 1A, B, C, D ) yellowish hyaline apically margined with brown. Crown flat, more or less horizontal, surface punctate with median short ridge on posterior margin, about 0.4 times as long as wide between eyes. Ocelli not prominent, closer to each other than to adjacent eye. Pronotum shallowly foveate on either side of median line in anterior half, posterior half slightly gibbous, anterior margin slightly convex, posterior margin medially concave, lateral margin somewhat straight, about 1.85 times as long medially as crown. Mesonotum shorter than pronotum. Forewing claval region densely punctate, apical margin obliquely truncate. Pygofer anterior margin deeply bilobed, posterior margin slightly sinuate, in lateral view about 1.2 times as long as height, ventro-cauadal process long, extending beyond dorsal pygofer margin, with some conical protrusions at end of ventral margin. Subgenital plate widest in mid-region tapering both anteriorly and posteriorly, apex acutely angled. Style broad in middle region, tapering forward and backward, apophysis curved ventrally with axe shaped apex. Aedeagal shaft (Fig. 2B, C, F, I ) bifurcate apically; ventral processes elongate, curved dorsally, longer than shaft. Other male genitalia characteristics as in Figs 1 and 2 .
