Diagnosis

Vein r of fore wing nearly linear with vein 3-SR ( Fig. 2F ); subapical segments of female antenna cylindrical ( Fig. 2J ); vein 2-M of fore wing without pigmentation ( Fig. 2F ); vein 1-M narrow apically; hind femur entire yellowish brown ( Fig. 2I ); third metasomal tergite about 1.4 × as long as second tergite ( Fig. 2H ).

Etymology

Named after the acutely protruding clypeus, from the Latin ‘ acutus ’ for ‘pointed’ and ‘ clypeus ’ for ‘shield’.
