Taxonomy and phylogeny
Campsomerinae was originally described by Betrem in 1972 as a sister group to the Scoliinae comprising the scoliid wasps with two recurrent veins. This subfamily was further divided into the Campsomerini for species with two submarginal cells and Trielidini for species with three submarginal cells.[ Following the discovery of the genus '' Proscolia'', the Campsomerinae and Scoliinae of Betrem were demoted to tribes, Campsomerini and Scoliini, under a newly-defined Scoliinae by Rasnitsyn in 1977][ and maintained as such by and Day ''et al.'' in 1981.][ In 1996, Argaman re-elevated the tribes to subfamily status, along with elevating Betrem's Trielidini to a separate subfamily as Colpinae. Argaman further subdivided his Campsomerinae into 8 tribes (Trisciloini, Tetrascitonini, Pseudotrielidini, Dobrobetini, Campsomerini, Colpacampsomerini, Megacampsomerini, and Dielidini) and his Colpinae into 5 tribes (Dasyscoliini, Curtaurgini, Heterelini, Colpini, and Trielidini)][ but did so without any phylogenetic analysis.][ Argaman's revisions to higher taxonomy, additionally, were not maintained in Osten's 2005 checklist, and Osten again treated the group as tribe Campsomerini.][ In a review of the scoliid wasps of North America, Kimsey ''et al.'' likewise maintained Campsomerini as a tribe but excluded the genus ''Colpa'' to maintain ]monophyly

, with the suggestion that ''Colpa'' and its allies more likely either represent a separate tribe as Colpini or a subset of Scoliini.[ The results of mitochondrial phylogenetics by Liu, van Achterberg, and Chen in 2024 corroborated a separate lineage comprising ''Colpa'' and ''Guigliana'', though used the name Trielidini instead of Colpini to follow ICZN guidelines.][
