Osorius boops SHARP, 1887: 679   (Figs 8 a-c)

Type material examined:

Panama: Volcan de Chiriqui, 25 – 4000 ft, 1 male, leg. Champion (syntype, BMNH)   .

Additional material examined:

Costa Rica: San José, km 117 Pan-Am Hwy. 19 km N San Isidro (83.42.20 W, 9.28 N), 1880 m elevation, 2 specimens, 20-25 Jun.1997, leg. S & J. Peck, CR 1P97 023, from flight intercept trap ( KU, UIC)   ; Alajuela, Peñas Blancas , 800 m elevation, 1 specimen, 19. May 1989, from flight intercept trap, leg. J. Ashe, R. Brooks, R. Leschen ( KU)   .

Diagnosis:

The species can be easily distinguished from the other Osorius species   by the prominent eyes and the narrow temples. In this respect it resembles O. affinis   , although temples are not distinctly narrowed in O. affinis   . Moreover, O. boops   is distinctly larger than O. affinis   , and 3 rd antennomere is twice as long as 2 nd antennomere.

Description:

Length: 8.0 mm. Colour: black, elytra dark reddish, lighter reddish at shoulders, abdomen red; legs and antennae lighter red; posterior edge of pronotum reddish.

Head :: 1.10 mm long, 1.50 mm wide; with eyes distinctly prominent and narrowed temples; clypeus with a broad lateral prominence and medially emarginate front edge; punctation fine and moderately sparse; distance between punctures approximately twice as wide as diameter of punctures; on average, surface with distinct isodiametric ground sculpture; scarcely shiny; few setiferous punctures on clypeus and some granular supraocular punctures at posterior edge of eyes; between eyes and neck two long setae. AntennaeAntennae as long as head and half of pronotum combined; 2nd antennomere only half as long as elongate conical 3 rd; 4 th antennomere again shorter; nearly as long as 2 nd; 5 th antennomere longer and slightly wider; subsequent antennomeres wider than 5 th, but decreasing in length.

Pronotum: 1.45 mm long, 1.65 mm wide; widest shortly behind anterior angles; narrowed to posterior angles with smooth emargination in front of posterior angles; lateral margin extremely small at anterior angles; distinctly widened to posterior angles; punctation similar as on head, but on average sparser; at least twice as wide as diameter of punctures; few setiferous punctures along lateral margin and one seta between midline and lateral margin near posterior third; surface with similar ground sculpture as on head and scarcely shiny.

Elytra: 1.90 mm long, 1.80 mm wide; with weak coriaceous ground sculpture; surface moderately shiny; punctation sparse and weak.

Aedeagus with apical part very long, slightly curved and ending in an acute apex.
