Osoriellus hirtulus (FAUVEL, 1891) new combination (Figs 21C, 27A)

Osorius hirtulus FAUVEL, 1891: 92

Type material: Venezuela: Colonia Tovar, 2 males, 2 females, 1.11.1888, leg. E. Simon (lectotype and syntypes ISBN).

Diagnosis: Among the species of this group with dense setiferous punctation of the pronotum, O. hirtulus is characeterised by its large size and the slightly emarginate clypeus.

Description: Length: 7.4-7.8 mm. Colouration: Black, legs dark red; antennae black.

Head: 1.2 mm long, 1.4 mm wide; eyes small and not prominent, temples one-third longer than eyes; front edge of clypeus with obtuse large prominence at each side and a deep emargination between them; with deep and dense setiferous punctures; distance between punctures on average as wide as diameter of punctures; small space on posterior disc and at base of antennae without punctures; setae yellow; shorter on clypeus than on disc; without microsculpture; surface shiny.

Antennae as long as head; second antennomere globular; third oval, half times longer than second antennomere; following antennomeres approximately quadrate; increasing in width.

Pronotum: 1.4 mm long, 1.6 mm wide; widest at anterior angles; continuously convergent to obtusely rounded posterior angles; at anterior angles one-third narrower than at posterior angles; lateral margin slightly elevated to posterior angles; setiferous punctures deeper and denser than on head; with wide impunctate midline; yellow setae long; pointing posteriad; without microsculpture; surface polished.

Elytra: 1.5 mm long, 1.35 mm wide; with similar punctation as on pronotum, but with weak coriaceous ground-sculpture, surface less shiny than pronotum; yellow setae pointing backwards.

Abdomen with similar setiferous punctation as on elytra and pronotum; base of abdominal segments with small transverse depression.

Protibia: 1.01 mm long, 0.32 mm wide; 8 spines on outer edge; apical spines on long digits; WLR: 0.4; in posterior aspect, comb of inner emargination nearly totally visible; posterior face sparsely covered by long yellow setae; on average, setae as long as protibial width.

Aedeagus nearly symmetric; apical lobe narrow and slightly pointing to left side.
