Diagnosis: The species is very similar to O. mexicanus in the size, the shape of the pronotum, and the absent microsculpture of the head and pronotum. It can be differentiated from that species by the darker colour, the denser punctation of the pronotum, and the digitate protibia.

Description: Length: 5.3 mm, Colouration: Dark brown; posterior edge of pronotum and elytra reddish; legs and antennae yellow.

Head: 0.75 mm long, 0.90 wide; coarsely and densely punctate except wide midline and moderately large area at base of antennae; interstices between setiferous punctures much shorter than diameter of punctures; supraoculare space coriaceously punctuate; surface without microsculpture and polished except postocular vertex with dense netlike microsculpture and matt surface.

Antennae with second and third antennomeres equally long, fourth to sixth antennomeres approximately quadrate; following antenomeres distinctly thicker.

Pronotum: 0.95 mm long, 1.00 m wide; widest at anterior angles; evenly convergent to posterior angles; posterior angles obtusely rounded; lateral margin extremely fine; in dorsal aspect, nearly invisible in anterior third; setiferous punctation coarse and deep; partly coriaceous; interstices between punctures less than half the diameter of punctures; on each side of smooth midline with row of approximately 11 punctures; laterally, punctures in irregular rows; surface without microsculpture, but with sparse micro-punctation; polished.

Elytra: 1.10 mm long, 1.10 mm wide; with coriaceous ground-sculpture and rows of deep and dense punctures; interstices between punctures much shorter than diameter of punctures; surface slightly shiny.

Abdomen distinctly and densely punctate except moderately wide midline; each puncture with long yellow seta.

Protibia: 0.73 mm long, 0.23 mm wide; thick, nearly semi-circular; with 10 spines on outer edge; apical three spines inserted on moderately long digits; WLR: 0.67; in posterior aspect, comb at inner emargination visible throughout its total length; posterior face densely coverd by thick yellow setae.

Aedeagus angulate in nearly rectangular angle; apical lobe long and slender and slightly sinuate to apex; apex nearly acute; inner side of apical lobe with three sensillae at middle.
