Diagnosis

Inner tooth of mandible 0.4× as long as apical tooth ( Fig. 34D ); lamella of third metasomal tergite posteriorly without tubercles ( Fig. 34M ); temple and face entirely yellow ( Fig. 34B–C ); head in dorsal view reddish brown without yellow spot around eye ( Fig. 34A ).

Etymology

Named after the yellow temple; ‘ flavus ’ in Latin is ‘yellow’.
