Head sub-rectangular, with rounded sides and largely rounded posterior angles. Eyes small and a little protruding.

Pronotum massive, longer and narrower than head, with very fine and dense, transverse micro-striation; dorsal series of 5 puntures and lateral series of 4-5 irregular punctures, all well visible. Elytra sub-rectangular, slightly dilated posteriad, longer and wider than pronotum, with scarcely marked humeral angles. Surface with two series of fine punctures near the suture, one median and one lateral. Abdomen with traces of very fine, transverse microstriation and fine, very sparse puncturation.

Posterior margin of 6° visible abdominal tergite and sternite prolongated in a more or less evident median lobe ( Figs 51-52 ). Tergite and sternite of the male genital segment as in Figs 53-54 . Aedeagus ( Fig. 55 ) about 1,2 mm long, ovoidal, narrow and elongated, with characteristic distal plate; parameres long and very narrow; inner sac with two long spines, one shaped like.

The new species differs from the congeners especially by the aedeagus.
