(Figs 24A, C, 27B)
Type material: Holotype, male: Panama: Veraguas, Cerro Tute, 4 km W of Santa Fe, 850 m elevation, male, 30.7.1995, leg. Gillogly (KNHM).
Paratypes: Panama: 1 female and 2 males with same data as holotype (KNHM); Costa Rica: Cartago Prov., Ref. Nac. de Fauna Silvestre Tapanti, 1.5 km E Station (83°46.90'W, 9°44.97'N), 1240 m elevation, flight intercept trap, female, 30.10.- 1.11.2001, leg. R. Brooks, #CR1B01 14 (KNHM, UIC); Ecuador: Napo Prov., 25 km W Tena, Tena-Talag Grande Road, 2000 ft elvation, litter near stream, female, 23.5.1993, leg. L. Herman, #2739 (AMNH); Napo Prov. 69 km NE Baeza, 15 km SW Reventador, 4600 ft elevation, (without abdomen), litter, 28.- 30.10.1988, leg. L. Herman (AMNH).
Diagnosis: Among the O.- hirtulus -group, O. pubicollis is characterised by the polished and shiny pronotum. Additionally, compared to O. setosus and O. pubescens, the pronotum is less convergent from anterior to posterior angles.
Description: Length: 5.8 mm. Colouration: Dark brown; legs and antennae lighter brown.
Head: 0.86 mm long, 1.14 mm wide; eyes moderately large; not prominent; as long as temples; sides of forehead emarginate; anterior edge of clypeus even with two minute granules at angles; setiferous punctation on vertex denser than on fore-head; wide midline and area at base of antennae impunctate; very weak netlike microsculpture; more distinct on punctate areas; surface moderately shiny.
Antennae slightly longer than head; second antennomere globular and as long as third; following antennomeres approximately quadrate; sixth to eleventh antennomeres thicker than preceding antennomeres.
Pronotum: 1.14 mm long, 1.26 mm wide; widest at anterior angles; slightly convergent to posterior angles; posterior angles widely rounded; lateral margin fine; finer at anterior angles than at posterior angles; setiferous punctation dense and deep; on average, interstices between punctures half as wide as diameter of punctures; wide midline impunctate; without microsculpture; surface polished and shiny.
Elytra: 1.34 mm long, 1.27 mm wide; as densely and deeply punctate as on pronotum; setiferous punctures hardly visible in coriaceous ground-sculpture.
Abdomen with dense setiferous punctation and narrow impunctate midline on tergites; netlike microsculpture weak; surface slightly shiny.
Protibia: 0.68 mm long, 0.20 mm wide; 8 spines at outer edge; apical four spines inserted on short teeth; WLR: 0.9; in posterior aspect, comb of inner emargination visible throughout its total length; posterior face with moderately dense setation; on average, setae as long as protibial width.
Aedeagus rectangularly angulate; asymmetric; left side of apical lobe with large basal plate; right side with central tooth; both sides of inner edge with several setae; apical lobe sinuate ending in hook-like acute apex.
Etymology: The specific name means with dense setose pronotum.
