Diagnosis: Among the similarly sized species without digitate protibial outer edge, O. verhaaghi is characterised by the slightly emarginate sides in front of the posterior angles. In this respect, it resembles O. fumarius and O. caliginosus , but these species are larger and the pronotal emargination is much deeper. Additionally, the shortly produced teeth at the outer angles of the clypeus are absent in O. fumarius and O. caliginosus .
Description: Length: 6.3 mm. Colouration: Black, legs and antennae brown.
Head: 0.90 mm long, 1.30 mm wide; eyes not prominent; as long as temples; sides of fore-head deeply sinuate; anterior angles of clypeus produced to short acute teeth; anterior edge of clypeus between lateral teeth even; setiferous punctation moderately dense and deep; density of punctation irregular; on average, interstices between punctures two to three times as wide as diameter of punctures; large area at base of antennae, small area on posterior vertex, and transverse area on posterior vertex impunctate; yellow setae hardly reaching adjacent puncture; supraocular and postoculare area with granulate punctures and short striae; distinct netlike microsculpture; surface matt.
Antennae shortly longer than head; second antennomere elongate and oval, slightly longer than conical third; following three antennomeres not wider than preceding antennomeres, but approximately quadrate, antennomeres 7 to 10 distinctly wider than preceding antennomeres, but also quadrate.
Pronotum: 1.16 mm long, 1.30 mm wide; widest at anterior angles; evenly narrowed to posterior angles; posterior angles obtusely rounded; lateral margin fine; slightly widened to posterior angles; in dorsal aspect, not visible close to anterior angles; setiferous punctation deep and moderately dense; impunctate midline widened posteriad; on average, interstices between punctures twice as wide as diameter of punctures; yellow setae short; shorter than diameter of punctures and interstice between punctures combined; between normal coarse punctures with micro-punctation; distinct netlike microsculpture; surface matt.
Elytra: 1.50 mm long, 1.44 mm wide; setiferous punctation moderately deep and dense; in irregular rows; coriaceous ground-sculpture weak; setae as short as on pronotum.
Abdomen with dense setiferous punctation; setae distinctly longer than on fore-body; netlike microsculpture distinct; surface matt; lateral punctures on tergite VII with striae.
Protibia: 0.66 mm long, 0.23 mm wide; 9 spines on outer edge; apical spines inserted on short digits; WLR: 1.47; in posterior aspect, comb of inner emargination visible throughout its total length; posterior face densely covered with long yellow setae.
Aedaegus angulate in nearly rectangular angle; basal lobe longer than apical lobe; apex obtuse; on inner edge with numerous sensillae.
Etymology: The specific name honours one of the collectors of the species, Dr. M. Verhaagh, from the Museum in Karslruhe, Germany, who collected intensively in the Panguana region.
