Type locality.

BRAZIL: Pará: Tucuruí [3.75°S, 49.67°W].

Type material.

Holotype male: "Tucurui 49°40'W, 3°45'S, PARA BRESIL" / "16-29/7/1985, piége d’interception, N. Degallier" / "Caterino/Tishechkin Exosternini Voucher EXO-00189" (UFPR).

Diagnostic description.

Length: 2.0 mm, width: 1.8 mm; as for generic description, plus the following specific characters: body rufescent; mandibles lacking basal incisor teeth; apices of first and sutural elytral striae connected by apical marginal elytral stria; basal propygidial stria nearly complete, only narrowly interrupted at middle; fine ground punctation of pygidia relatively conspicuous; pygidium equilaterally subtriangular, apex bluntly subacute; prosternal keel with weak carinal striae in basal half only; prosternal lobe with well impressed marginal stria along middle portion; postmesocoxal stria bent laterad behind coxa, ending freely; only few punctures along metepisternal margin subserially arranged, without marginal stria on edge of mesoventrite; metepisternum itself with fragmented longitudinal stria; postmetacoxal stria not distinguishable from lateral strigosity of 1st abdominal ventrite.

Remarks.

This species has its pygidial apex subacute (Fig. 16A), but not particularly prolonged. This in combination with the posteriorly abbreviated postmesocoxal stria and lack of lateral marginal metaventral stria will distinguish it from its congeners.

Etymology.

This species’ name refers to its very smooth, glabrous body surface.
