'''Ageniellini''', known as the '''mud-nesting spider wasps''', is a tribe of spider wasps in the subfamily Pepsinae.

==Description== The Ageniellini are slender-bodied spider wasps. They are distinguished from most other Pompilidae by their petiolate abdominal structure and typical absence of a transverse carina on the first segment of the gaster. These traits are, however, shared with ''Melanagenia'' of the tribe Pepsini, which is separated by the lack of malar space, deep lateral sulcus of the pronotum, and wing venation.<ref name="Waichert et al. 2015"/><ref name="Wahis et al. 2009"/>

==Distribution== The tribe Ageniellini is cosmopolitan.<ref name="Shimizu et al 2010"/>

==Behavior== Members of Ageniellini have one of three lifestyles that either invade the nests of other spider wasp nests as kleptoparasites, build their own nests in dry soil, or build thimble-shaped nests out of mud.<ref name="Shimizu et al 2010"/> The most common of these nesting strategies is building mud nests, which are frequently communal in contrast to most other spider wasp groups.<ref name="SANBI 2014"/> As typical of the rest of the family, the Ageniellini provision their nests with a single spider and then lay an egg on it.<ref name="Waichert et al. 2015"/> Most of the species remove the legs of their spider prey before bringing it to the nest.<ref name="SANBI 2014"/><ref name="Carvalho-Filhoa"/> Amputation of spider legs is rarely done by species other than those of the Ageniellini.<ref>Yamaguchi, S., Shimizu, A., Yamasaki, T., Kurczewski, F.
