Antennae: With 11 antennomeres; scape 4.0 times longer than pedicel; pedicel elongate, somewhat globular, shorter than antennomere III; antennomere III more than 2.0 times longer than antennomere IV; antennomeres IV–VIII sub-equal in length, longer than wide and rounded in cross sectional view; antennomeres IX–XI asymmetrical. Compound eyes large, round. Pronotum: Parallel-sided, convex. Setae inconspicuous. Slightly longer than wide, with well-developed hind angles. Lateral pronotal ridge entire. Notosternal suture as long as the hypomeral base. Hypomeron simple, without lateral antennal grooves. Elytron: Elongate, convex. Setae inconspicuous. Disc with very strong striae. Interstices convex, elevated. Legs: Prothoracic legs shortest; metathoracic legs longest, slightly longer than prothoracic legs. Metatarsi, including claws as long as tibia. Metatarsomere I shorter than II–V combined. Metatarsomeres I–III simple. Metatarsomere IV simple, as wide as III. Metatarsomere V elongate. Claws simple. Venter: Setae inconspicuous. Elytral epipleura enlarged, not grooved. The metepisterna are largely obscured by elytral epipleura. Metacoxal plates medially 3.0–6.0 times wider than laterally. Tarsal grooves absent on meso- and metaventrite Abdomen with five visible ventrites, medially convex. Last visible ventrite evenly rounded caudally.
