The body is dark brown, and the distal half of the fore tibiae are paler, with fore tarsi gray-brown, and mid and hind tarsi pale brown. Forewings are brown, and hind wings are dark brown. Vertex has four ante-ocellar setae. Antennal segment 1 is small, and segment 2 is somewhat produced at the outer distal edge which is broadly rounded. Antennal segments 3 and 4 each have a simple sense cone. The principle sense cone on antennal segment 5 is on the inner distal edge of the segment. The pronotum is slender, and the dorsal surface has short transverse scallop-like lines across the pronotum. Males are brachypterous. Abdomen is slender, with tergites and sternites having long, nearly parallel, transverse lines (Zur Strassen, 1967).
