Identification.

Beside the presence of only the anterior elytral seta, and therefore setal formula 2111, this species is set off from the other members of the Mecyclothorax gourvesi group by the basally broad pronotum; MPW/BPW = 1.32 (Fig. 34A). The head, frons, and vertex, are covered with a well-developed isodiametric mesh, the sculpticells in more transverse rows amongst the wrinkles of the frons, regularly isodiametric on the neck. The pronotal disc is covered with a regular transverse mesh, sculpticell breadth 2 × length, and the discal elytral intervals are lined with a well-developed transverse mesh with sculpticells 3 –4× broad as long. The male aedeagal median lobe has a very broad, very short apex with an acuminate tip at the juncture of the apical face and ventral margin (Fig. 36A). Standardized body length 5.2 mm.

Distribution and habitat.

The unique holotype specimen was collected by Elwood Zimmerman between 1675 and 1900 m elevation on Mont Aorai. The specimen was beaten from moss on either a tree or a shrub.
