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’.
