Diagnosis: In contrast to Blackwelder’s (1943) statement, the species is more similar to O. micros and O. brevicornis than to O. eggersi due to the distinct microsculpture of the pronotum. In contrast to O. micros , the sixth antennomere is wider, similar as in O. brevicornis . Compared to O. brevicornis , the pronotum of O. lewisi is more distinctly convergent from anterior to posterior angles and the head and the pronotum are darker. The holotype is incomplete, without head and pronotum. The description based on the further material.
Description: Length: 3.9 mm. Colouration: Dark brown; legs and antennae light brown.
Head: 0.59 mm long, 0.78 mm wide; eyes not prominent, longer than temples; sides of fore-head deeply emarginate; anterior edge of clypeus even; setiferous punctation dense and moderately deep; on vertex, interstices between punctures half as wide as diameter of punctures; on clypeus, interstices wider; isodiametric microsculpture deep and dense; surface matt.
Antennae as long as head and half of pronotum combined; second antennomere oblong; as thick and long as conical third; fourth and fifth antennomeres as wide as third, but shorter; approximately quadrate; following antennomeres increasing in width; tenth antennomere slightly wider than long.
Pronotum: 0.78 mm long, 0.82 mm wide; widest at obtuse anterior angles; sides in anterior half less narrowed than in posterior half; posterior angles widely rounded; setiferous punctation deep and larger than on head; moderately wide midline impunctate; lateral margin fine; at anterior angles nearly invisible in dorsal aspect; isodiametric microsculpture distinct; surface matt.
Elytra: 0.95 mm long, 0.84 mm wide; coriaceous groundsculpture deep; setiferous punctation in irregular rows; only slightly visible in deep ground-sculpture; surface matt.
Abdomen with dense and deep setiferous punctation; on tergites, narrow midline impunctate; microsculpture irregular; surface more shiny than on pronotum and head.
Protibia: 0.84 mm long, 0.27 mm wide; with 9 spines at outer edge; WLR: 2.0; in posterior aspect, inner comb of inner emargination covered in middle; posterior face densely covered by long yellow setae.
Aedeagus slender with slightly curved, nearly straight apical lobe; apex of apical lobe obtusely rounded; without sensillae at inner edge of apical lobe.
