Diagnosis:
O. laevicollis is similar in size to O. dentatus , O. costaricensis and O. sublaevis , but is, on average, slightly larger than these species.The dense microsculpture and matte pronotal surface resembles that of O. costaricensis and O. sublaevis , but pronotal punctation is distinctly larger and denser. In contrast to O. costaricensis , the apex of the aedeagus is extremely acute and long.
Description:
Length: 7.8 mm. Colour: black, legs and antennae reddish brown.
Head :: 1.2 mm long, 1.5 mm wide; front edge laterad without prominence, but with a wide emargination centrally; punctation dense and moderately deep; on disc, distance between punctures shorter than diameter of punctures; with sparser punctation on clypeus; a small midline and an area above base of antennae impunctate; surface with very weak isodiametric microsculpture; shiny; with several supraocular granular setiferous punctures; with short longitudinal striae at temples behind eyes.
AntennaeAntennae with 2 nd antennomere short and nearly circular; conical 3 rd antennomere only slightly longer than 2 nd; antennomeres 4 to 10 increasing in width; 4 th antennomere quadrate; 10 th antennomere wider than long; relation length: width 0.77.
Pronotum: 1.4 mm long, 1.6 mm wide; widest at anterior edge; sides slightly narrowed in anterior half; distad more distinctly narrowed and slightly emarginate in front of posterior, obtusely rounded angles; lateral margin narrow in anterior half, widened to posterior angles; punctation finer and distinctly sparser than on head; distance between punctures two to three times wider than diameter of punctures; a narrow midline impunctate, but with short central groove; surface with isodiametric microsculpture; slightly shiny.
Elytra: 1.7 mm long, 1.6 mm wide; with deep coriaceous ground sculpture; punctation present, but scarcely visible between deep ground sculpture; in spite of deep ground sculpture, surface shiny.
Abdomen with very sparse and fine punctation and weak, netlike microsculpture; surface shiny; tergites without setae.
Front tibiatibia at outer edge with 9 spines; apical three ones inserting on short teeth.
AedeagusAedeagus oval in shape with extremely short apical part suddenly narrowed in front of acute apex.
