Diagnostic description.

Length: 1.81-1.97 mm, width: 1.47-1.62 mm; body oval, subquadrate, rufescent; frons flat, frontal stria varied across frons, from nearly complete to fragmented to broadly interrupted; epistoma and labrum narrowed, labrum 1.5 × as wide as long, truncate; pronotal disk finely punctate, with ~20 coarser lateral punctures; marginal pronotal stria not descending onto hypomeron; lateral submarginal pronotal stria complete, very close to marginal at sides, not meeting slightly recurved anterior marginal in front; elytra with subhumeral striae absent, striae 1-4 complete, 5th and sutural striae present in apical two-thirds; venter almost entirely lacking microsculpture, with only vestigial fragments at sides of sterna; prosternal keel truncate at base, with carinal striae strongly converging, parallel in apical third, joined by narrow anterior arch; mesoventrite not projecting; propygidium broad with scattered small punctures, with vestigial microsculpture; pygidium lacking microsculpture, also with sparse small punctures, fine marginal striae nearly complete, usually obsolete only in basal fourth. Male: segments 8-10 indistinguishable from those of Operclipygus hamistrius (see Figs 57 A–D), and tegmen indistinguishable from that of Operclipygus geometricus (see Fig. 57J).

Remarks.

This distinctive species may be recognized by the lack of an outer subhumeral stria, the relatively flat frons, the numerous lateral pronotal punctures, and the complete marginal mesoventral stria (Fig. 58C), which is not reached by the subangulate mesometaventral stria.
