Female
holotype
: 3.6 x 2.0 mm.
Description. Body
with sternites, pygidium and most of elytra pale reddishbrown, other areas dark reddishbrown including elytral apices. Pubescence lacking above.
Head
with scattered minute punctures; frons bisulcate, sulci widely separated; eyes reniform, weakly protuberant; antennal club as long as funicle.
Rostrum
subequal in length to head, widened from antennal insertions to apex, width at apex more than twice as wide as frons.
Antennae
inserted at basal 1/4 of rostrum; club elongatecompact, nearly as long as funicle; basal and middle club segments subequal in length; terminal segment shorter; funicular segment 1 ovoglobose, subequal to scape; segment 2 clavate, slightly shorter than 1; 3 and 4 like 2, slightly longer; 5–7 short, more or less moniliform.
Pronotum
smooth, shiny, with shallow minute punctures, distinctly bifoveate; anterior collar distinct, dorsally widened and vshaped.
Scutellum
wider than long, 5sided, posterior margin weakly angled at middle.
Elytra
longer than wide, in dorsal view only slightly narrowed posteriorly, without transverse depression behind scutellum; humeri simple, rounded, moderately protuberant; striae very small, weakly impressed, weakly channeled at base; intervals flat, smooth, wide.
Profemora
ventrally angulate; apex of angle with minutely ridged protrusion.
Distribution

type
locality in
Panama

Comments.
Omolabus longiclava
is of questionable status. Sharp’s description does not agree with the
type
specimen that was examined. The antennae of the female
holotype
(
Figs. 61–63
) is not unusually long as the original description and name implies. Males are needed in order to determine if Sharp’s description was actually based on a male. However, the size, color and pronotal fovea seem to distinguish the species. It is closely related to
O
. sedatus
but the pronotal fovea distinguish it from that species.
Host plants.
Host plant association for this species is unknown.
