Diagnosis.
Body (5.50-6.60 mm) not or slightly compressed longitudinally, elongate; derm glossy, glabrous, at most with sparse setae on elytra. Rostrum rather long and robust, much shorter than pronotum; longer than head; often wider before antennal insertion (equal width throughout: Wollaston (1873)). Antennae inserted above middle of rostrum in lateral view so that anterior part of scrobes visible from above; scapes reaching or passing hind margin of eyes, longer than funicles; funicles with seven segments. Head with forehead between eyes as broad as or broader than base of rostrum; postocular constriction not touching eyes. Eyes large, distance between eyes and postocular constriction shorter than diameter of eye. Pronotum not bisinuate at base (if weakly bisinuate, tarsal segment 5 broadest near base and tapering distally, or derm matt); triangular, truncate at base, as wide as elytral base. Elytra evenly parallel-sided, linearly truncated at base, not setose, recurved at their apex. Legs. with pro- and mesocoxae very widely and subequally separated, metacoxae less remote than pro- and mesocoxae; procoxae not very close to hind margin of prosternum; tibiae normal; tarsal groove of front tibiae not or bluntly pointed laterally; tarsi with segment 3 small, simple, entire or slightly notched, segment 5 normal, clavate, not compressed ( Wollaston 1873, Hustache 1924, Morimoto 1973, Zhang 1992).
