Diagnostic description.

As with the preceding, this species is very similar to Operclipygus communis , differing only in a few characters, as follows: length: 1.53-1.68 mm, width: 1.25-1.34 mm; lateral submarginal pronotal stria present in basal two-thirds or more; 4th and 5th elytral striae more strongly impressed, not fragmented. Male: genitalia indistinguishable from those of Operclipygus belemensis (see Figs 38E, G–H).

Remarks.

This species has little to distinguish it from the preceding two beyond the longer lateral submarginal pronotal stria (Fig. 37G). This character is, however, very consistent over a wide geographic range. The type series is limited to those specimens from northern Suriname.

Etymology.

This species’ name means ‘harmless’.
