Antennae unicolorous dark reddish brown, club robust. Eyes large. Pronotum finely, sparsely punctate; sides rounded, posterior angles broadly obtuse. Elytral striae weakly impressed; strial punctures large and closely spaced; interstriae minutely, sparsely punctate. Flight wings fully developed. Vertical face of mesosternum flat, not medially carinate. Metasternum coarsely, densely punctate laterally; finely, sparsely punctate medially. In both sexes, mesofemur with lobed expansion of apex of posterior margin. Metafemur robust, with a toothlike expansion of apex of posterior margin in male, lobed in female. Mesotibia in both sexes broad and spinose; metatibia more slender and spinose. Male with dense pale setae ventrally on pro- and mesotarsi. Median lobe of aedeagus ( Fig. 68, 69 View Figures 65–69 ) elongate, cylindrical, strongly angulate dorsoventrally in lateral view; paired apices elongate, parallel. Parameres slender in dorsal view, broad in lateral view, reaching apex of median lobe, each bearing two apical setae. Inverted internal sac with elongate median tubelike structure and apical triangular sclerite with two posterior projections. Spermatheca of 2 connected spheres.
