Identification
Characters of the Pepsinae: Ageniellini: spines at apex of hind tibia of even spacing and length, transverse groove in second sternite, lacks pocket in basioposterior corner of third discal cell, hind tibia usually smooth in both sexes, labrum at least partially exposed, this is the only agenielline with a crease on side of first tergite, sides of first tergite in dorsal view concave subbasally.
Similar to Auplopus but differs in the following: bristle-like hairs on mentum not divided into two groups; only sparse erect hair on the propodeum (hairs long & abundant in Auplopus), concolorous black (some Auplopus are concolorous but can be separated by structure).
Mentum:

Widespread in the U.S. east of the Rockies and in the southwest.
Habitat
Woods and woodland edges.
Season
May-Sep in the northern parts of its range
Food
Adults uncommonly visit flowers. Females provision nests with Lycosid and Agelenid spiders.
Life Cycle
Females build mud nests as in Auplopus. There is probably more than one generation per year.
