DESCRIPTION:

Male

Measurements ♂: length: 8.5–9 mm, width: 4–4.5 mm.

Body: Laterally slightly convex, relatively short, slightly bent, broader in middle of elytra; abdomen concave; short process at base of prosternum rounded; dorsal side totally black or orangish-brown with head always blackish; flagellum yellowish; underside and legs black; slightly shining.

19

Head: broad; clypeus rounded, entirely reflexed, clypeus and vertex totally covered with tubercles; frons impunctate; antennae with 10 antennomeres, with club longer than funicle.

Thorax: pronotum rectangular, wider than long; sides slightly angular in middle; all margins carinate; anterior angles projecting and reaching posterior margin of eyes; with small separated rounded punctures, closer on lateral margins; small impressed point on lateral margins; scutellar shield almost triangular, punctate like disc of pronotum.

Elytra: longer than wide; epipleura complete; primary costae more convex than intervals; secondary striae irregularly punctate, coalescent; striae with a line of small close rounded punctures; humeral and apical calli slightly marked.

Pygidium: triangular, apex truncated, carinate along anal plate, not projecting postero-ventrally and not surpassing apex of elytra; imbricate-punctate.

Venter: upper part of metaventrite with close horseshoe-shaped punctures, sparsely and rounded punctures towards median part; abdominal ventrites with cressent-shaped punctures.

Legs: protibiae tridentate, larger claw elongate, 1/3 shorter than last tarsomere, pro-and mesotarsal larger claw cleft; larger claw of metatarsus twice longer than smaller and uncleft.

Hairs: dorsal side covered with short yellowish, squamous, decumbent setae; erected and isolated from median part to declivity of margins of elytra, very close on top of humeral calli; long separated erected brownish setae on the anterior part of lateral margins of pronotum; shorter, closer and yellowish on antennae and canthus; underside covered with short white, squamous, decumbent setae, longer on sides of mesoventrite, median part of mesoventrite glabrous; sparse long decumbent brownish-yellow setae inserted in setigerous punctures, one single on meso and metacoxae, transversal line on abdominal ventrites, close along anal plate; close long decumbent white setae along anterior and posterior margins of prosternum, longer and erected on base of labium; pygidium covered with isolated white squamous setae, short and decumbent along posterior margin, progressively longer and erected from base to disc, disc almost glabrous; outer sides of protibiae and femora with short, white, squamous, decumbent, setae; longer on inner sides.

Aedeagus: in lateral view, parameres elongate and slightly curved; in dorsal view, lateral margins of parameres parallel from base to apex, exit for endophallus from base, apex narrowed, sinuate and notched on apico-internal angle.

Female

Measurements ♀: length: 8–10.5 mm, width: 4–5 mm.

Differs from ♂ by: totally black or reddish-brown, larger, laterally more convex and abdomen convex; antennae with club as long as funicle; pygidium strongly projecting postero-ventrally and surpassing apex of elytra; protibiae with apical teeth broader and longer.
