Familia: Carabidae
Genus: Mecyclothorax
Name
Mecyclothorax teatara Perrault, 1986: 448 – Wikispecies link – Pensoft Profile
Identification
This species is easily diagnosed by the broadly ellipsoid elytra and small, little transverse pronotum, MPW/PL = 1.25 (n = 2) (Fig. 23D). It shares pronotal proportions with the sympatric Mecyclothorax ramagei (Fig. 22E), but differs in the larger body size, standardized body length 5.3–5.6 mm, and by the presence of two supraorbital setae each side; setal formula 2221. Mecyclothorax teatara is characterized by elytral intervals covered by dense transverse lines, with only occasional cross-connections resulting in transverse sculpticells versus the transverse mesh characterizing Mecyclothorax ramagei. The male aedeagal median lobe is nearly symmetrically expanded apically, with a rounded ventral and a subangulate dorsal expansion, and the apex face is rounded (Fig. 24G). The ostial canal parallels the dorsal margin, and the right paramere is narrowly extended to a whiplike apex.
Distribution and habitat
This species is known from 800–1100 m elevations on Mont Teatara, Tahiti Iti. One specimen was collected via pyrethrin fogging of mossy horizontal logs and mossy tree trunks.
