Diagnosis

Both teeth of mandible blunt and of subequal length (Fig. 3K); first discal cell of fore wing comparatively wide (Fig. 3F); second submarginal cell of fore wing large and wide; metasomal carapace coarsely rugose (Fig. 3H); temple as long as eye in dorsal view (Fig. 3B); hind tibia weakly swollen (Fig. 3E); mesosternum with satiny sheen and superficially coriaceous; parastigma dark brown and vein 1-M of fore wing brown.

Etymology

Named after the blunt and subequal mandibular teeth, from the Latin ‘ aequoreus ’ for ‘same level’ and ‘ dens ’ for ‘tooth’.
