Diagnosis: The species highly resembles O. franckei in the size, shape and punctation of the pronotum. The pronotal punctation is slightly denser than in O. franckei and the pronotal microsculpture is deeper and denser. Thus, in contrast to O. franckei , the pronotal surface of O. rugipennis is matt.

Description: Length: 4.5 mm, Colouration: Dark brown, elytra slightly lighter brown with suture and anterior edge reddish; front legs red, middle and hind legs as well as antennae yellow.

Head: 0.5 mm long, 0.75 mm wide; anterior edge even; without any granules; deeply and densely punctate; interstices between setiferous punctures shorter than diameter of punctures; with impunctate midline; at base of antennae impunctate and surface polished; on vertex microsculpture deep and circular; surface matt.

Antennae with third antennomere slightly shorter than second; fourth antennomere longer than wide and fifth to sixth antennomeres quadrate; following antennomeres wider than long and distinctly thicker than preceding antennomeres.

Pronotum: 0.80 mm long, 0.80 mm wide; sides widest at anterior angles; evenly convergent to posterior angles; posterior angles rounded; lateral and posterior margin narrow and visible throughout its total length; with large and dense setiferous punctures; impunctate midline; on each side of midline with row of 8 punctures; lateral punctures in irregular rows; on average, interstices between punctures shorter than diameter of punctures; setae long and yellow; netlike microsculpture distinct, but less deep than on head; surface moderately shiny.

Elytra: 0.95 mm long, 0.85 mm wide; coarsely and densely punctate; partly with coriaceous setiferous punctures; irregular rows of 8 to 12 punctures; with very weak microsculpture; surface nearly polished.

Abdomen densely and deeply punctate except moderately wide impunctate midline; microsculpture weak and surface shiny.

Protibia: 0.52 mm long, 0.16 mm wide; 8 spines on outer edge; apical 3 spines inserted on short digits; WLR: 2.2; in posterior aspect, comb of inner emargination totally visible; posterior face with moderately dense setation.

Aedeagus angulate in nearly rectangular angle; apical lobe long; apex obtuse; 7 sensillae at inner edge of apical lobe.
