( Figs. 14 , 31–32 )

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

Diagnosis. Arpactophilus brochus is the only New Caledonian species in the genus with a clypeus that has a small lateral pointed tooth on each side which are connected by a straight line with no medial tooth and a labrum with four teeth ( Fig. 31 ). Another distinctive character is the presence of fine longitudinal ridges on the gena ( Fig. 14 ), which can only be found in A. cuspidis , but this species differs greatly in the extensive yellow markings and medially projecting apical clypeal margin ( Fig. 43 ).

Remarks. The coloration of mandible, labrum and scape is variable (with coloration from yellow to dark brown).
