( Figs. 4 , 37–38 )

Arpactophilus caledonicus Bohart, 1999: 98 [♀: holotype BPBM].

Diagnosis. Arpactophilus caledonicus is the only New Caledonian species in the genus with the combination of a forewing with one submarginal cell, a frontal carina present from median ocellus almost up to apical margin of clypeus, a dorsally-interrupted occipital carina ( Fig. 6 ), a brown or blackish frons ( Fig. 37 ), a transverse pattern of carinae with reticulae on the dorsal surface of propodeum (similar to pattern in Fig. 21 ) and yellow legs.

Remarks. Two poorly preserved specimens show the same characters, but have a mostly brown clypeus with only little yellow lateral markings. Both have slightly darker legs.
