The Pepsinae are a subfamily of the spider wasp family, Pompilidae, including the two genera of large tarantula hawks, as well as many genera of smaller species.

Biology

A female spider wasp generally captures and stings a spider to paralise it; this is for their larvae to feed on. However, the wasps of this subfamily display a range of nesting behaviours: *using preexisting cavities; *using the immobilised spider’s burrow; *digging a burrow in soil; *building nests of mud; *parasitoids; and *kleptoparasites.

Taxonomy

Pepsinae can be defined by: *sternite 2 with a distinct transverse groove; *mesofemur and metafemur without subapical spine-like setae set in grooves or pits; *the metatibia with apical spine-like setae of uniform length, the setae not splayed; and *vein Cu1 of fore wing is simple at its base, without any definite downward deflection, i.e. the second discal cell (2D) is without a ‘pocket’.Brothers, D.

These include 16 genera of Ageniellini, 7 genera of Deuterageniini, 48 genera of Pepsini, 11 genera of Priocnemini, 1 genus of Psoropempulini, and 1 genus unplaced to tribe.
