Synonyms and other taxonomic changes
Recently invalidated names:
Ageniella partita (male of A. arcuata)
Ageniella obscura (taxonomic priority, valid name is A. utilis)
Ageniella blaisdelli, Ageniella conflicta may actually be conspecific with A. accepta based on molecular evidence (Waichert et al., 2011).
Although some can be moderately large, most are rather small, near 10 mm.
Metasoma constricted basally so that it appears short-petiolate.
Propodeum practically bare, except in one subgenus (Ameragenia) where the posterior tibiae are serrate.
No crease delimiting an epipleurite on T1
S7 of male rather small and not as distinctly ridged longitudinally as in Phanagenia and Auplopus.
Females with at most a few weak setae on the mentum
Clypeus without a trough-like impression paralleling its lateroapical margin
One species or another occupies almost every conceivable terrestrial habitat from deserts to deciduous forests. See individual species for more specific information.
Throughout most of the warm season, males of some species can be found as early as May in the north (Ohio) (N. Fensler, unpublished data).
As adults some species are known to visit flowers (various umbellifers). The young feed on spiders, of course. They provision with various species of Agelenidae, Salticidae, Thomisidae, and Lycosidae.
Other genera of the tribe Ageniellini: Phanagenia, Auplopus, and Priocnemella.
