Identification.

This species is characterized by the broadest, most robust body, and the acutely protruded, glabrous, pronotal hind angles (Fig. 12B). The elytra are remarkably broad and foreshortened, with the humerus broadly extended and rounded at the base of the lateral marginal depression. The head is covered with transversely stretched isodiametric sculpticells arranged in transverse rows. The pronotal disc bears a shallow transverse mesh, the sculpticell breadth 2 –4× length, and the discal elytral intervals are covered with a well-developed transverse mesh with sculpticell breadth 2 –3× length. Setal formula 2101; standardized body length 7.2-8.1 mm.

Distribution and habitat.

Perrault collected the female holotype, 20-xii-1977, at 1000 m elevation on Mont Marau. Earlier that same year - 29-30-vi-1977 - another female was collected "at night" from the summit of Marau, 1490 m elevation (W.C. Gagné and S.L. Montgomery; BPBM).
