description: Osoriellus levyi n. sp.
(Figs 58 A-C, 96D)
Type material: Holotype, male: Ecuador: Napo Prov., Jatun Sacha Biol. Station, 21 km E Puerto Napo (77°36.48'W, 01°04.06'S), 400 m elevation, collected by flight intercept trap in virgin rain forest, 15.7.1994, leg. Levy & Genier (KNHM).
Diagnosis: The species resembles O. bicolor in size, colouration and micro-punctation of the fore-body. The pronotal punctation in O. bicolor is much deeper and denser than in O. levyi. In O. bicolor, the interstices between the punctures are approximately half as wide as diameter of punctures, whereas they are at least as wide as diameter of punctures in O. levyi. The strong curved apical lobe of the aedeagus and the acute apex is characteristic for O. levyi, too.
Description: Length: 3.3 mm. Colouration: Dark brown; posterior margin of pronotum and clypeus yellow; legs and antennae yellow.
Head: 0.46 mm long, 0.63 mm wide; eyes slightly prominent and as long as temples; sides of fore-head deeply sinuate and convergent to anterior margin of clypeus; sides of clypeus parallel; anterior margin of clypeus even, without teeth at outer angles; setiferous punctation moderately dense; punctures large, but not deep; wide midline and area at base of antennae impunctate; on average, interstices between punctures as wide as diameter of punctures; without microsculpture except small areas with remains of extremely weak microsculpture; between coarse punctures with micro-punctation; surface shiny and mostly polished.
Antennae as long as head and half of pronotum combined; second antennomere oval and slightly longer than wide; conical third antennomere smaller than second and only as long as wide; following three antennomeres approximately as wide as third, but shorter; fourth antennomere quadrate, sixth nearly twice as wide as long; antennomeres 7 to 10 much thicker than preceding antennomeres and distinctly wider than long.
Pronotum: 0.65 mm long, 0.64 mm wide; widest at obtuse anterior angles; evenly and slightly narrowed to posterior smoothly rounded angles; lateral margin extremely fine; in dorsal aspect, visible throughout its total length; setiferous punctation moderately dense, but punctures larger and deeper than on head; wide midline impunctate; on average, interstices between punctures as wide as diameter of punctures; in row adjacent to midline, interstices between punctures shorter; without microsculpture; surface polished and shiny.
Elytra: 0.80 mm long, 0.72 mm wide; with deep and dense ground-sculpture; setiferous punctation in irregular rows; punctures hardly visible in ground-sculpture; on disc 4 rows of punctures.
Abdomen with dense setiferous punctation and narrow impunctate midline; with remains of microsculpture; surface moderately shiny.
Protibia: 0.35 mm long, 0.15 mm wide; nearly semicircular; 9 long spines at outer edge; WLR: 3.0; in posterior aspect, comb of inner emargination partly covered; setation on posterior face dense.
Aedeagus with long prominence in middle and strongly curved apical lobe ending in acute apex.
Etymology: The specific name derived from the collector of the species, Mr. Levy.
