Type material examined: Jamaica: Blue Mountain Peak (holotype in MZC) .

Further material examined: St. Lucia: Micoud Mahut Quilesse Reserve (60°56'W, 13°50'N), male, 17.07.1980, leg. L.S. Mahunka, #68 ( NHMH) GoogleMaps .

Diagnosis: Concerning the pair of long clypeal teeth, O. notmani resembles O. bovis and O. cornutus . O. notmani is much larger than these two species that range between 4.5 and 4.9 mm length. In contrast to these species, the microsculpture of the head and the pronotum is weak, whereas at least the microsculpture of the head of O. bovis and O. cornutus is deep. In contrast to the species of similar size, O. notmani is light reddish brown and not dark brown or black.

Description: Length: 5.9 long. Colouration: Light brown; elytra lighter reddish; legs and antennae red.

Head: 0.80 mm long, 1.25 mm wide; eyes small; not prominent; temples 1.5 times as long as eyes; sides of fore-head evenly converegnt to anterior angles of clypeus; anterior angles of clypeus produced to acute teeth; lateral teeth one-forth as long as width between them; clypeus between acute teeth emarginate; on vertex, setiferous punctures denser than on fore-head; wide midline and area at base of antennae impunctate; on fore-head, interstices between punctures as wide as diameter of punctures; near neck, interstices between punctures half as wide as diameter of punctures; netlike microsculpture weak; surface slightly shiny.

Antennae slightly longer than head; first antennomere as long as antennomeres 2 to 4; second antennomere oval; third conical; both antennomeres equally long; following antennomeres approximately quadrate; antennomeres 6 to 10 slightly wider than preceding antennomeres.

Pronotum: 1.16 mm long, 1.34 mm wide; widest at acutely produced anterior angles; slightly narrowed posteriad to widely rounded posterior angles; lateral margin fine; in dorsal aspect, shortly in front of anterior angles invisible; setiferous punctures large and in irregular rows; punctation irregularly dense; on average, interstices as wide as diameter of punctures or slightly wider; wide midline impunctate; with sparse micro-punctation between normal setiferous punctures; netlike microsculpture weak; surface shiny.

Elytra: 1.16 mm long; 1.25 mm wide; with coarse coriaceous ground-sculpture; rows of setiferous punctures weaker than on head and pronotum; surface less shiny than on pronotum.

Abdomen with dense setiferous punctation except impunctate midline.

Protibia: 0.71 mm long, 0.23 mm wide; with 9 spines on outer edge; 3 apical spines inserted on long digits; WLR: 0.76; in posterior aspect, comb at inner edge shortly covered in middle; anterior face with few setae at apex; posterior face sparsely covered by yellow setae.

Aedeagus angulate in nearly rectangular angle; apical lobe long and at inner edge with triangular prominence; one sensilla at base of prominence; six sensillae apically to prominence.
