Genus: Mecyclothorax
Name
Mecyclothorax fosbergi Perrault, 1979: 9; 1988: 232 – Wikispecies link – Pensoft Profile
Identification
Relative to Mecyclothorax fosbergioides, this species can be diagnosed immediately by the reduced microsculpture that results in a glossy dorsum. The pronotum is narrow, MPW/PL = 1.07, and the humeral angles are proximate due to the narrow elytral base, MEW/HuW = 2.36. The male aedeagal median lobe is elongate and narrow, the apex expanded both dorsally and moreso ventrally, with a flattened apical face (Fig. 13E). The male flagellar plate is moderately long, its length estimated at 0.45× the distance from parameral articulations to the apex in the uneverted aedeagus. Setal formula 2222; standardized body length 8.25 mm.
Distribution and habitat
This species is known only from the holotype specimen collected by the botanist F.R. Fosberg, from dead Cyathea fern fronds at 915 m elevation above the floor of Papenoo Valley on the lower flank of Mont Orohena.
