. Clypeus large and expanded to conceal labrum, weakly convex, and truncate to subtruncate apically. Ground punctation present. Eyes well developed, weakly convex, and separated by 4–5 times the diameter of one eye. Eyes constricted medially by anterior and posterior emargination. Frontoclypeal suture usually appearing absent. Antennae with 9 antennomeres, ca. 3/4 × as long as the width of the head; antennomeres 7–9 densely pubescent and forming a loose club. Club length ca. 4 × the width of the apical segment. Maxillary palps bearing four palpomeres, with palpomeres 2 and 4 similar in size and both slightly longer than palpomere 3. Palpomeres 3 and 4 with sides nearly symmetrical. Stipes laterally with long fine yellow setae. Labial palps bearing three palpomeres; palpomere 3 much longer than 1 & 2 combined. Palpomeres 2 and 3 bearing long setae. Mentum length ca. half the width, depressed anteromedially, pubescent. Gula constricted medially, forming an elongate triangle anteriad and a more obtuse triangle posteriad.

. Pronotum convex, often meeting seamlessly in outline with elytra; broadened posteriorly meeting elytral margins; pronotal ground punctation often more weakly impressed than that on the elytra. Pronotal marginal bead well developed laterally, becoming shallower anteromedially. Scutellum punctate; forming an equilateral triangle. Elytral striae absent except for a sharp sutural stria arising in the posterior one-third and continuing to apex; ground punctation often well impressed and dissimilar to pronotal punctation; marginal bead well developed. Prosternum small and flat. Mesoventrite with a well-developed, raised linear process; angular, anteriorly proceeded by an elevated sub-parallel ridge that reaches posteriad to meet elevated process of the metaventirte. Metaventrite very sparsely pubescent; elevated medially along entire length, beginning low and broad posteriad and becoming more narrow, elevated, and subparallel anteriad as it meets the posteriad portion of the mesoventral ridge process. The process arises anteriad to the metacoxae and proceeds between the mesocoxae. Pro- and metacoxae narrowly separated. Mesocoxae separated the process of the mesoventrite. Mesocoxae large and extending the width of the mesoventrite. Metacoxae flattened, extending the width of the metaventrite. Profemora densely pubescent basally on both dorsal and ventral surfaces; meso- and metafemora glabrous with a few isolated setae along anterior margin. Femora and tibiae noticeably flattened dorso-ventrally. Femora with tibial grooves developd throughout the posterior margin. Tibia spinose with larger spines apically. Tarsi with moderately dense setal brush ventrally. First metatarsomere longer than second. Tarsal claws relatively small and moderately curved.
