Diagnosis:
The species can be differentiated from the similar species in size by the lighter coloured brown elytra when comparing it to the black elytra in all other species.
Description:
Length: 8.7 mm. Colour: black; pronotum and elytra dark brown.
Head :: 1.5 mm long, 1.8 mm wide; with dense and deep punctation; distance between punctures on average as wide as diameter of punctures; isodiametric microsculpture moderately deep; surface shiny; front edge of clypeus emarginate with undulate inner side of lateral teeth; with one long and several extremely short setae on each side of middle; labrum wider than long; lateral striae behind eyes short and weak; with several supraocular granular punctures.
AntennaeAntennae with 2 nd antennomere oblong; 3 rd conical antennomere scarcely longer than 2 nd; antennomeres 4 to 6 slightly longer than wide; subsequent antennomeres quadrate.
Pronotum: 1.7 mm long, 2.0 mm wide; sides widest at front angles, forming a short prominent tooth; more or less continuously narrowed to posterior angles; posterior edge margined; with punctation and microsculpture as on head; surface shiny; a fine and sparse micro-punctation between normal, coarse punctures.
Elytra: 2.2 mm long, 2.0 mm wide; with weak coriaceous ground sculpture, and sparse and fine punctation; surface shiny, nearly polished.
AedeagusAedeagus small and elongate with a short acute apical part.
