Distribution

Species known only from New Caledonia, Grande Terre ( Fig. 12E ). See additional details in Jennings & Austin (2005: 416).

Remarks

The eight specimens from Aoupinié differ from Pseudofoenus ritae (Cheesman, 1936) by the presence of a frontal carina and of two medial teeth on the mandibles, and agree with the description and measurements of P. caledonicus . However, they differ from P. caledonicus in their size and coloration, these specimens being smaller (females: 7.4–8.3 mm (vs 8.7–10.0 mm for caledonicus ); males: 7.9–8.5 mm (vs 10.5 mm for caledonicus )) and brown with reddish parts (vs dark brown for caledonicus ). The Aoupinié males have a smaller metasoma compared to the mesosoma (2.54–2.65 × as long as the mesosoma; vs 2.80 × for caledonicus ), and the first flagellomere is 1.55–1.68 × as long as the second flagellomere in both males and females (vs 2.00–2.40 × for caledonicus ). With the actual knowledge of the Pseudofoenus fauna of New Caledonia, we are reluctant to describe a new species based on these differences and consider they are intraspecific variations. Additional specimens and barcoding may solve this problem.
