Diagnostic description.

This species is extremely similar to the preceding, differing as follows: length: 1.37-1.40 mm, width: 1.09-1.12 mm; pronotum with anterior submarginal stria with recurved ends slightly longer, between one-third and one-half pronotal length; elytra with 1st dorsal stria frequently obsolete at apex, 4th stria present in apical half, 5th stria consistently very slightly shorter than 4th; prosternal keel with carinal striae not weak toward base, generally connected posteriorly, subparallel toward front, united in anterior arch about one-fourth keel length from presternal suture; propygidium with punctures smaller, denser, separated by about one-half their diameters; pygidial marginal sulcus deep, but simple with margins only very faintly crenulate. Male genitalia indistinguishable from those of Operclipygus subterraneus (see Figs 36 F–H).
