Osorius continentalus View in CoL sp. n. ( Figs 30 View Fig a-c, 3 7 C)

Type material:

Holotype, male: Panama: Bocas do Toro , 3 km W of Fortuna Hwy. continental divide, 1050 m elevation, 12.7.1995, leg. A. Gillogly ( KU).


The species resembles O. morio , O. laevicollis , and O. dubius in size or shape of pronotum. It is slightly longer than O. laevicollis . Compared to O. morio , punctation of elytra is much more indistinct. In O. morio , elytral punctation is distinctly visible and larger. Compared to O. laevicollis , microsculpture of pronotum is isodiametric, while it is netlike in O. laevicollis . Antennae are more slender than in O. laevicollis . Compared to O. dubius , surface of pronotum is shinier and punctation is denser and deeper.


Length: 9.0 mm. Colour: black.

Head :: 1.3 mm long, 1.7 mm wide; eyes not prominent, front edge of clypeus with lateral denticulate prominences and a deep emargination in between; an indistinct obtuse prominence in central emargination; punctation deep and moderately dense; distance between punctures on average as wide as or slightly wider than diameter of punctures; a space at base of antennae without punctures; with few postocular striae; with weak isodiametric microsculpture, surface shiny.

Antennae with 2 nd antennomere more or less globular; 3 rd antennomere conical and only slightly longer than 2 nd; subsequent antennomeres increasing in width; antennomeres 4 to 6 longer than wide; 7 th antennomere quadrate; subsequent antennomeres slightly wider than long.

Pronotum: 1.7 mm long, 1.9 mm wide; with acute tooth-like anterior angles; sides behind anterior angles slightly narrowed; nearly parallel; distad from middle to posterior angles distinctly narrowed and slightly emarginate; lateral margin narrow behind anterior angles; distad widened to posterior angles; punctation similar to head, but slightly sparser; weak microsculpture isodiametric; surface shiny.

Elytra: 2.0 mm long, 1.9 mm wide; with coriaceous ground sculpture; punctation scarcely visible in deep ground sculpture.

Aedeagus with long triangular apex; ending in an acute top.


The species name derived from ‘continent’ and refers to the location at continental divide Hwy, where it was found.
