Taxonomy and phylogeny

As Psenini, this taxon was previously treated as one of 4 tribes under the subfamily Pemphredoninae within Crabronidae. Following phylogenetic analyses Crabronidae was found to be paraphyletic due to the exclusion of Anthophila. As part of this revision, Pemphredoninae was also found to be polyphyletic and was split into 4 families. Psenini and Odontosphecini were combined and elevated to Psenidae. Ammoplanina (a subtribe of Pemphredonini) was elevated to Ammoplanidae, the remaining Pemphredonini to Pemphredonidae, and Entomosericini to Entomosericidae.^[1][3]

Psenidae is the sister lineage to Ammoplanidae, while Pemphredonidae is sister to Philanthidae.^[1]
