Type material examined: Haiti: Massif de la Hotte, 2000- 4000 feet, female (paratype in NMNH) .

Further Material examined: Dominican Republic: Prov. La Vega, 7.2 mi SE Constanza Rd. to San José de Ocoa, 5000 ft elevation, litter nr. stream, male, July, 29, 1991, leg. L. Herman, # 2578-81 ( AMNH) .

Diagnosis: The species resembles O. rugipennis and O. franckei in size. Compared to O. rugipennis , the pronotal punctation is sparser. Compared to O. franckei , the pronotal microsculpture is more distinct and the surface is less shiny.

Description: Length: 4.7. Colouration: Black; legs and antennae light brown.

Head: 0.61 mm long, 0.94 mm wide; eyes not prominent; as long as temples; anterior angles of clypeus produced to short acute teeth; anterior edge between teeth even; setiferous punctation distinct and moderately dense; on average, interstices between punctures as wide as diameter of punctures; at bae of antennae, small area impunctate; on supraoculare area with granulate punctures; netlike microsculpture distinct; surface slightly shiny.

Antennae as long as head and half of pronotum combined; second antennomere oblong and slightly longer than conical third; following antennomeres increasing in width; antennomeres four to ten approximately quadrate and with long yellow setae.

Pronotum: 0.96 mm long, 1.04 mm wide; widest at anterior angles; anterior angles rectangular or slightly produced to extremely short acute teeth; sides in anterior half nearly parallel; in posterior half distinctly narrowed to obtuse posterior angles; lateral margin fine; in dorsal aspect, not visible close to anterior angles; setiferous punctation large; in irregular rows; row adjacent to impunctate midline with approximately 10 punctures; on disc, interstices between punctures as wide as or slightly wider than diameter of punctures; between setiferous punctation with dense micro-punctation; netlike microsculpture distinct; surface slightly shiny.

Elytra: 1.13 mm long, 1.08 mm wide; with weak coriaceous ground-sculpture; setiferous punctures in irregular rows.

Abdomen densely punctate with setiferous punctures; netlike microsculpture weaker than on fore-body and surface shinier.

Protibia: 0.51 mm long, 0.19 mm wide; with 7 spines at outer edge; apical spines on short digits; WLR: 1.66; in posterior aspect, comb of inner edge visible throughout its total length; posterior face densely covered by yellow setae.

Aedeagus with long and slender apical lobe; apical lobe smoothly curved to acute apex; inner edge of apical lobe with row of several sensillae.
