Parastephanellus mouensis Aguiar in Aguiar & Jennings, 2005: 10 .

Material examined

NEW CALEDONIA • 1 ♀; Grande Terre, Province Nord, Poindimié, Katalupaik ; 20°51′11.12″ S, 165°0′34.66″ E; alt. 306 m; 18 Oct.–2 Nov. 2017; E. Poirier leg.; Malaise trap n°KAT3-MAL3; MNHN .

Distribution

Species known only from New Caledonia ( Fig. 12F ). See additional detail in Aguiar & Jennings (2005: 10).

Remarks

Previously, P. mouensis was known only from the holotype female collected at Mount Mou. During the 2017 “Our Planet Reviewed” expedition, an additional female was collected in a Malaise trap at Katalupaik, nearly 200 km north-west of the type locality. This female is 13.5 mm long and smaller than the holotype (18.8 mm). Otherwise, it differs from the type by: antennae with 29 flagellomeres, with tyloids absent from 23 rd– 29 th; petiole as strongly sculptured ventrally as dorsally, coarsely strigate all along its ventral surface; frons central tubercule yellow basally; genal stripes ivory, slightly narrower; hind tarsomere 1 ivory; T-III–VII apical margin brown, slightly lighter than the rest of the tergite. We believe this female belongs to P. mouensis and the differences described above to be intra-specific variations.
