Fig. 11

Diagnosis

Apical half of vein 1-M of fore wing dark brown and basal half yellow ( Fig. 11F ); face granulate-rugose, with median bump ( Fig. 11D ); mesoscutum and scutellum coarsely rugose ( Fig. 11G ); pterostigma large ( Fig. 11F ); apical tooth of mandible rather slender ( Fig. 11F ); hypopygium apically acute, with up-curved short triangular protuberance ( Fig. 11E ).

Etymology

Named after the yellow head, from the Latin ‘ flavus ’ for ‘yellow’ and ‘ caput ’ for ‘head’.
