Genus: Mecyclothorax
Name
Mecyclothorax viridis Perrault, 1978b: 158; 1986: 454 – Wikispecies link – Pensoft Profile
Identification
Within the Mecyclothorax viridis group this species shares with Mecyclothorax ninamu the absence of discernible microsculpture on the dorsal body surface and cordate pronotum (Figs 31A, B), but the dorsal body coloration is not so dark, with the head a dark rufobrunneous, contrasted with the metallic piceous elytral disc. The overall body is narrower, with the pronotum less transverse, MPW/PL = 1.11–1.15 (n = 2), and the elytra more narrowly ovate. The elytral striae are more well developed in this species, with the eighth interval subcarinately elevated above striae 7 apicad the subapical sinuation, and striae 2–4 nearly as deep as the sutural stria 1 on the elytral apex. The male aedeagal median lobe is similar to that observed in males of Mecyclothorax nimanu (Figs 30C, D), but the apical expansion is more narrowly rounded, and the apical face more convex. Setal formula 2221; standardized body length 3.4–3.9 mm.
Distribution and habitat
This species is known only from near the summit of Mont Aorai, with all specimens collected between 1750 and 1900 m elevation.
