( Figs. 23–24 )

Arpactophilus abdominalis Bohart, 1999: 98 [♀: holotype MNHN].

Diagnosis. Arpactophilus abdominalis is the only New Caledonian species in the genus with the combination of a bulge on sternum II (as in Fig. 2 ), a red metasoma, yellow mandible ( Fig. 23 ), two submarginal cells, and a complete occipital carina ( Fig. 5 ).

Remarks. Bohart (1999) failed to mention the structure of the occipital carina in the original description despite the fact that A. abdominalis is one of the few species with two submarginal cells to have a continuous carina.

Material examined. 4 ♀: (1x) “ NEW CALEDONIA 9902: 21°47’S x 166°04’E, 450m, Mt Do gate. 27 Nov 2000. GB Monteith. Pyrenthrum, trunks & logs” [QM]; (1x) “ NEW CALEDONIA 9955: 22°06’S x 166°39’E, Riv. Bleue, Kaori Geant. 11 Nov 2000, P. Bouchard. Beating veg.”; (1x) “ NEW CALEDONIA 12277: 21°20’S x 164°58’E, 30m, Pindal, dry forest site. 27 Apr 2005. G.B. Monteith. beating” [QM]; (1x) “ NEW CALEDONIA Anse Vata, 23.X.1958; C. R. Joyce Collector” [ BPBM].
