Head slightly shorter than pronotum, compound eyes somewhat prominent, spherical, widely separated; two ocelli relatively small and well elevated on a tubercle; antenna subequal to third of the body, 4-segmented, first segment shortest, second longest, every segment uniformly slender; rostrum extending to mesocoxae. Collar present, not depressed. Pronotum nearly trapeziform with sinuous flanks, 1.7 times as wide as long. Fore and mid legs subequal in length, hind legs much longer than mid legs; femora short and stout, corresponding tibiae distinctly slenderer and longer than femora, tarsi shorter than half length of corresponding tibiae, tarsi trimerous. Base of membrane with a black comma-like marking. Abdomen oval, spiracle conspicuous.
