Monotypic in North America, Phanagenia bombycina
Characters of the subfamily pepsinae, tribe ageniellini (nearctic only): 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.
This genus (species) is very similar to Auplopus but differs on the following characters: bristle-like hairs on mentum are in one group (not divided into two groups as in Auplopus), with only sparse erect hair on the propodeum (not with long, abundant hairs as in Auplopus), concolorous black (some Auplopus are concolorous but can be separated by structure).
Widespread. Found in the U.S. east of the Rockies and the southwest.
Woods and woodland edges.
Late spring (May) to early Autumn (September) in the northern parts of its range.
Adults uncommonly visit flowers. Females provision nests with Lycosid and Agelenid spiders.
Females build mud nests as in Auplopus. There is probably more than one generation per year.
