Type material.

Holotype male: "Panama: Chiriquí Prov. La Fortuna. "Cont. Div. Trail" 08°42'N, 82°14'W, 1150m, 9-12 VI 1995, J. Ashe & R. Brooks#186, ex: flight intercept trap"/ “SEMC0903667” (SEMC).

Diagnostic description.

This species is extremely similar to Operclipygus assimilis , except for the following characters: length: 1.65 mm, width: 1.28 mm; body slightly shorter, more broadly rounded; second antennal annulus not interrupted on dorsal surface; coarser lateral pronotal punctures not as numerous, <20; lateral submarginal pronotal stria slightly abbreviated at base; anterior submarginal pronotal stria recurved posterad only about one-sixth pronotal length; elytral stria 4 nearly complete, just barely abbreviated at base. Male: more or less indistinguishable from Operclipygus gratus (see Figs 43 A–D) except in having a slightly larger overall, and relatively broader tegmen (Fig. 43L).

Remarks.

While the characters listed in the description will help to distinguish this species from Operclipygus gratus and Operclipygus assimilis , examination of the aedeagus is necessary for unambiguous identification.

Etymology.

This species’ name refers to its limited distribution, being known only from the type locality in Chiriquí, Panama.
