Osorius integer SHARP, 1876: 384   ( Figs 24 View Fig a-c)

Type material examined:

Brazil: Amazonas : Tefé, 1 male, without further data (holotype, BMNH)   .

Additional material examined:

Ecuador: Rio Napo, Onkone Gare Camp (76°26' W, 0°39' S), terra firme forest, flower fall leaf litter, at night, 220 m elevation, 1 female, 8.10.1995, leg. G.E. Ball ( KU) GoogleMaps   .

Diagnosis:

The species resembles O. laevigatus   , O. wasmanniwasmanni   and O. peruvianus   in size and punctation of the pronotum. It can be distinguished from O. laevigatuslaevigatus   and O. wasmanniwasmanni   by a weak microsculpture on the pronotum that is absent in O. laevigatuslaevigatus   and O. wasmanni   . In contrast to O. peruvianus   , postocular striae are absent.

Description:

Length: 9.3 mm. Colour: black; legs and antennae dark brown.

Head :: 1.40 mm long, 1.80 mm wide; short eyes slightly prominent, not longer than temples; lateral edge of clypeus only slightly emarginate; base of mandibles scarcely visible in dorsal aspect; front edge of clypeus straight with an obtuse short lateral prominence; surface deeply and densely punctate; distance between punctures as wide as to moderately shorter than diameter of punctures; with feeble and close microsculpture; surface more or less shiny; with several supraocular and postocular striae and several granular setiferous punctures.

AntennaeAntennae with 2 nd antennomere short and globular; 3 rd one conical and slightly longer than 2 nd one; subsequent antennomeres more or less quadrate increasing in width.

Pronotum: 1.75 mm long, 2.00 mm wide; widest at anterior edge with tooth-like prominent front angles; continuously narrowed to posterior edge; slightly emarginate in front of posterior angles; lateral margin narrow at front angles; distad from middle distinctly widened to posterior angles; punctation deep and dense, but on average less dense than on head; distance between punctures slightly wider than diameter of punctures, but on some parts also closer than diameter of punctures, in particular, adjacent to small impunctate midline; with shortly depressed furrow in posterior half.

Elytra: 2.15 mm long, 2.15 mm wide; with elongate and deep punctures, in particular, at base with striate punctures; moderately dense punctation slightly sparser than on pronotum; surface without microsculpture; shiny.

Abdomen with fine and sparse punctation; distance between punctures at least twice as wide as diameter of punctures; surface without microsculpture.

Front tibia with 9 spines at outer edge; two apical ones inserting on long teeth.

Aedeagus circular in shape with short smoothly curved apical part ending in an acute apex.
