Type material.
Holotype male: "BRAZIL: Pará: Belém, Utinga (IPEAN), 1°27'S, 48°26'W. Piège d’interception. xi.1984" / "Caterino/Tishechkin Exosternini Voucher EXO-00295" (UFPR). Paratypes (7): 4: same data as type (FMNH, AKTC, MSCC); 3: same locality as type but xii.1984, FIT (MNHN, CHND).

Diagnostic description.
This species is very similar to the preceding, differing only in a few characters, as follows: length: 1.44-1.78 mm, width: 1.19-1.40 mm; prosternal carinal striae nearly reaching presternum (longer than in Operclipygus communis ); 4th dorsal stria more strongly impressed to base; 5th stria longer, present in apical half, rarely fragmented; coarser pygidial punctures slightly larger and denser. Male: genitalia very similar to Operclipygus communis (Figs 38E, G–H), but with all parts more heavily sclerotized, especially T8; T8 (Fig. 38F) with greater distance between basal emargination and basal membrane attachment line, especially darkened in this area, basal apodemes of T8 broader, subtruncate apically, basal emargination shallower, more nearly rounded; all else as in preceding.
Remarks.
This species can be most easily separated from close relatives by the characters in the description, particularly the longer prosternal striae and coarser pygidial punctures (Fig. 37F), but should be dissected for unambiguous identification. We narrowly restrict the type series to the immediate type locality due to some variation among other specimens.
Etymology.
This species’ name refers to its primary occurrence in and near the city of Belém, Pará, Brazil.
