This species shares well-developed microsculpture on head, pronotum and elytra with Mecyclothorax castaneus Perrault, the sculpticells a mixture of isodiametric and transverse on frons, transverse on pronotal disc, and of dense transverse lines on the elytral intervals. The discal elytral striae are distinctly punctate in this species, with the punctures in the basal third of striae 1–4 expanding the breadth of the striae, a character shared with Mecyclothorax mapo Liebherr of Moorea. However Mecyclothorax mapo differs by transverse-mesh elytral microsculpture and obsolete microsculpture on head and pronotum. This species differs from both Mecyclothorax castaneus and Mecyclothorax mapo by the obtuse-rounded pronotal hind angles, versus right and sharp hind angles in those two species. Whereas the two type specimens of Mecyclothorax castaneus (Perrault 1986) variably exhibit one or two dorsal elytral setae (one the more common condition), the two specimens of this new species plus those of Mecyclothorax mapo are uniformly bisetose; setal formula 2221. Beetles of this species exhibit standardized body length 4.3–4.5 mm versus 3.8–4.1 mm for Mecyclothorax castaneus. The type series of Mecyclothorax mapo includes individuals with body length ranging 3.8–4.4 mm. (Liebherr, 2012).
The two specimens of this species were found at 1060 and 1100 m elevation, in low-stature Weinmannia and Metrosideros forest. One specimen was collected in a pyrethrin fog sample from moss growing on a Metrosideros trunk, the second by beating vegetation along the margins of openings in the forest. Mecyclothorax tihotii and Mecyclothorax anaana were the two species found syntopically in these situations. (Liebherr, 2012).
