Diagnosis
Diagnosis. Female gaster short ovate, 1.0-1.4x as long as mesosoma (Fig. 139); forewing with 8-10 admarginal setae and postmarginal vein 1.4-1.5x as long as stigmal vein (Fig. 144); legs and petiole yellowish brown (Fig. 138), femora frequently dark brown; male flagellomeres 1-4 with basal setae in a whorl (Fig. 151). Similar to Omphale phruron but with coxae completely pale and shorter gaster in female. Male genitalia: phallobase (Fig. 486) with volsellar setae on short extensions and with apex of setae 0.4x the length of setae from apex of phallobase, digitus 0.8x as long as wide; aedeagus short and stout (Fig. 486), with penis valves 1.3x as long as wide.
