Description. Color and pubescence: Body distinctly bluish-black with extremities brownish black. Pubescence inconspicuous, consisting of short brownish reclinate setae. Size: Male (n = 5) 2.2 × 0.8 mm to 2.3 × 0.9 mm; Female (n = 5) 2.4 × 0.9 mm to 2.7 × 1.2 mm. Head quadrate, moderately punctured; punctures small round; interspaces minutely granulose; frons about twice as wide as width of rostral base; eyes large sub-circular, strongly protuberant. Rostrum about 1.5 times longer than head; sides sub-parallel, only slightly widened apically. Antenna inserted near basal 2/5 of rostrum; scape and funicular segment 1 narrowly oval, subequal; funicular segments 2-4 sub-equal, narrowed; segment 5 like 2-4 but shorter; segments 6-7 ovoglobose, subequal in length to segments 2-4 but more robust; club abrupt; basal and middle segment subequal; terminal segment slightly longer than basal and middle segments, weakly acuminate. Pronotum longer than wide, widest just behind middle, densely set with setigerous punctures; interspaces around punctures with single row of minute granulations. Scutellum small, rectangular, twice as wide as long. Elytra about twice as long as pronotum, widest just behind middle; humeri simple; striae moderately impressed, rounded, similar throughout; intervals weakly raised, with single row of setigerous punctures; interspaces between striae with single setigerous puncture. Thoracic pleura and sterna with dense coarse setigerous punctures. Abdominal ventrites distinctly concave, sparsely punctured, minutely granulose laterally, with numerous short erect and semierect setae through middle.

Distribution. Specimens are recorded from Costa Rica and Panama ( Fig. 88 ).

Comments. Adults of this species are strongly bluish-black with a densely punctured pronotum. The aedeagus ( Fig. 62 ) has a parallel-sided median lobe with the pedon apex weakly widened and 3-sided. The tectum is elongate, parallel-sided and apically narrowed to a point. The tegminal cap piece is finger-like with a distinct knob-like pigmented apex bearing numerous short setae. Endophallic bands are linear, moderately long and distinctly pigmented.

Plant association. A single female is recorded from Inga cocleensis Pittier (Fabaceae-Mimosoideae) in Panama.
