Diagnosis.

2.3-2.4 mm (mean = 2.34 mm; n = 5), 2.56-2.67 × as long as wide. This species is distinguished by the elytral apex attenuate and weakly emarginate, declivity strongly sulcate along interstriae 2, declivital interstriae 1-3 unarmed, declivity glabrous, declivital interstriae 3 clearly elevated and costate, and declivity smooth, shiny.

Similar species.

Distribution.

Brazil (Mato Grosso), Ecuador* (Orellana), Peru (Loreto).

Biology.

Specimens were collected by canopy fogging.

Remarks.

Wood (2007) incorrectly reported the holotype’s location as MZUSP. The holotype is in MEFEIS.
