In  O. eggersi, the outer edge of the apical lobe of the aedeagus is sinuate ending in an acute apex, whereas in  O. humicolait is evenly curved ending in an obtuse apex.  O. eggersialso resembles  O. carinicollisfrom the remaining-speciesgroup, but  O. carinicollishas a distinctly digitate protibia, it is slightly smaller and the punctation of the pronotum is slightly finer.  O. eggersiseems to be variable concerning the punctation of the pronotum and the number of sensillae on the apical lobe of the aedeagus. The specimens from Jamaicashow a denser pronotal punctation than the specimens from Cuba, St. Thomas, and the DominicanRepublic and only two instead of three apical sensillae.   Description: Length: 3.7 – 3.8 mm. Colouration: Brown; elytra slightly lighter; abdomen light brown; legs and antennae yellow.  Head: 0.55 mmlong, 0.70 mmwide; fore-head slightly elongate; distance from eyes to front margin 1.5 times as long as temples; densely and distinctly punctate; interstices between setiferous punctures half as wide as diameter of punctures; small area on central clypeus and another area at base of antennae impunctate; seta pointing posteriorly; surface without microsculpture; polished and shiny.  Antennaewith first antennomere as long as three following antennomeres; second antennomere oval and as long as conical third; antennomeres 4 to 6 small, approximately quadrate; antennomeres 7 to 10 distinctly thicker and wider than long.  Pronotum: 0.70 mmlong, 0.75 mmwide; widest at anterior angles; evenly convergent to posterior angles; slight emargination in front of posterior angles; lateral margin fine; coarsely and densely punctate; interstices between setiferous punctures as on head, but punctures deeper; moderately wide midline impunctate; setae pointing posteriorly; between coarse punctation with sparse micro-punctation; surface without microsculpture, polished and shiny.  Elytra: 0.75 mmlong, 0.75 mmwide; with coriaceous ground-sculpture and deep and dense setiferous punctation, punctures slightly visible in coarse groundsculpture; yellow setae pointing posteriorly; surface less shiny than on pronotum.  Abdomenwith even denser setiferous punctation than on pronotum, but punctures finer; surface with weak netlike microsculpture; less shiny than on pronotum.  Protibia 0.44 mmlong, 0.14 mmwide; with 9 long spines at outer edge; apical spines on short digits; WLR: 2.5; in posterior aspect, comb of inner emargination visible throughout its total length; posterior face densely covered by long yellow setae.  Aedeagusrectangularly angulate; upper edge of apical lobe sinuate ending in acute apex; inner edge of apical lobe with two groups of sensillae. 3447076336 FMNH Eggers Virgin Islands 18.333334 West Indies 35 266 1 holotype 3447076362 1915-07-05 AMNH Lutz & Mutchler Puerto Rico 18.4 San Juan 1275 -66.1 35 266 F 4003 1 holotype 3447076639 2007-10-15 IES A.
