Diagnosis.

Length: 2.18-2.84 mm, width: 1.75-2.37 mm; body rufo-brunneus; frons with median portion of frontal stria well impressed; supraorbital stria briefly interrupted at vertex; pronotum with anterior submarginal stria detached from lateral portion, slightly recurved posterad at apices, more or less parallel to outwardly arcuate anterior emargination, anterior marginal stria interrupted for short distance at middle; elytra generally lacking any fragments of inner subhumeral stria, sutural stria nearly or fully complete, frequently with the 4th stria arched over at the base nearly meeting it; pygidium with punctation mainly fine, dense, with larger punctures interspersed only near the base, marginal sulcus complete, deep, crenulate. Male genitalia (Figs 18 A–D, F): T8 with unique secondary sclerotization along edge of apical emargination; S9 narrow, evenly expanded to apex, with midline sclerotization distinct; tegmen abruptly narrowed toward apex, strongly narrowed and slightly bent near base in lateral aspect.

Remarks.

The best characters for separating Operclipygus panamensis and Operclipygus crenatus are the details of the anterior pronotal margin and submarginal stria, with the central portion of the pronotal margin outwardly arcuate in Operclipygus panamensis (Fig. 17A), and the anterior submarginal stria always detached from the lateral submarginal. In Operclipygus crenatus , the anterior margin is not outwardly arcuate (Fig. 17C), and the lateral and anterior portions of the submarginal pronotal stria are usually connected behind the median pronotal gland openings. The body color and pygidium also fairly readily distinguish the species, with Operclipygus crenatus consistently darker (Fig. 17C), and with a more coarsely punctate pygidium (Fig. 17D).
