DESCRIPTION

Male

Measurements and ratios ♂ (n = 12): LB: 10 – 11.5 mm, lB: 5 – 5.5 mm; LB/lB: 1.71 (1.62 – 1.91); LP/lP: 0.50 (0.49 – 0.54); LE/lE: 1.33 (1.25 – 1.47).

Body: laterally convex, relatively elongate, slightly bent, broader in middle of elytra; abdomen concave; short process at base of prosternum rounded; brownish-yellow with vertex, frons, antennae, apical teeth of protibia, all margins and tarsi reddish-brown to blackish-brown, shining.

Head: broad; clypeus strongly reflexed; in dorsal view, lateral margins strongly sinuate from middle part to apex; slightly striated transversely; vertex slightly striated transversely to anterior part, deep rounded points from middle part to frons; frons with deep elongate points; antennae 10-segmented, with club longer than funicle.

Thorax: pronotum subrectangular, broader than long; sides uniformly rounded from base to apex; all margins carinate; anterior angles projecting and reaching posterior margin of eyes; impressed point on lateral margins; scutellum digitiform; separated crescent shaped points.

Elytra: longer than broad; epipleura complete; costae elevated; intervals with close rounded points; striae formed by lines of close deep rounded points; humeral and apical calli slightly marked.

Pygidium: triangular, carinate along anal plate, slightly projecting postero-ventrally and not surpassing apex of elytra, apex rounded.

Legs: protibiae tridentate; larger claw elongate, as long as last tarsomere; pro-and mesotarsal larger claw cleft; larger claw of metatarsus 2 times longer than smaller and uncleft.

Hairs: clypeus with sparse setae inserted in points on sides; pronotum with separated setae inserted in points; elytra covered with short, white, squamous, decumbent setae; separated setae inserted in setigerous points on lateral margins from pronotum to basal part of elytra, close on canthus; sternites with sparse setae inserted in setigerous points; sparse, white, squamous decumbent setae on metasternum; mesofemora with setae inserted in setigerous points, metafemora with short white decumbent setae; longer erected yellowish setae on disc of pygidium.

Aedeagus: in lateral view, dorsally straight from base to middle part, angular to apex, bisinuate ventrally; in dorsal view, parameres slightly narrowing from base to apex, broad and short, laterally slightly sinuate; strongly notched to apico-internal angle.

Differs from ♂ by: slightly broader; clypeus slightly reflexed and, in dorsal view, not laterally sinuate form middle part to apex; abdomen convex and apical tooth of protibia rounded.
