Type material.

Holotype male: "PARAGUAY: San Pedro, Cororô. 23°28'N[sic, should be S], 56°39'W. 180m, 27-30 Oct 1999. J.Jensen" / "Caterino/Tishechkin Exosternini Voucher EXO-00267" (FMNH).

Diagnostic description.

As above, this species is very similar to Operclipygus mortavis , but with a number of minor differences: length: 2.56 mm, width: 2.37 mm; ground punctation of most of body coarser, more conspicuous, especially on sides of pronotum, with coarse punctures nearly continuously scattered from basal plicae to sides; pronotal disk more strongly, somewhat irregularly convex; elytra with outer subhumeral stria weakly impressed, interrupted at middle and strongly abbreviated in anterior half, inner subhumeral stria represented by a fine series of punctures, not impressed as a distinct stria; 1st abdominal ventrite with anterior stria interrupted at middle for about width of one metacoxa. Male genitalia (Fig. 23E): as in preceding species, but with tegmen broader, sides more arcuate than parallel, narrowing more strongly to base.

Remarks.

The very weak inner subhumeral stria provides the most straightforward character for separating this species from the preceding.

Etymology.

This species is named for the country from which it is exclusively known.
