Synonyms and other taxonomic changes
The scoliid subfamilies used on BugGuide are alternatively represented as tribes (Campsomerini and Scoliini) united under a differently-defined Scoliinae.
Our representation of Campsomerinae has variably been sub-divided (either as tribes or subtribes). As used by Argaman (1996), these tribes would include Campsomerini (for the present genera of
Dielis,
Pygodasis, and
Xanthocampsomeris) and Colpini (for the present genera of
Colpa and
Crioscolia). These subtaxa were not used by Osten (2005).

Subsequent phylogenetic studies by Khouri et al. (2022) suggest establishing separate tribes of Campsomerini and Colpini, with Colpini as most sister to Scoliini. They additionally found that
Dielis pilipes grouped within
Xanthocampsomeris rather than dielis but did not formally transfer the species.

narrow, L-shaped enclosure
Overview of subtaxa
Campsomerine genera may be further divided into two groups (formerly treated as tribes or subtribes). Members of the
Campsomeris group / Campsomerini s.s. (
Dielis,
Pygodasis, and
Xanthocampsomeris) have two submarginal cells. Members of the
Colpa group / Colpini (
Colpa and
Crioscolia) have three submarginal cells.

Members of the Colpa group are separated into two subgenera, Colpa (Colpa) and Colpa (Crioscolia) based on the interantennal space in females and the antennal structure in males.
Colpa (Colpa): female interantennal space less strongly elevated, male with flagellum not modified
Colpa (Crioscolia): female interantennal space forming a strongly elevated platform, male with proximal part of flagellum conspicuously narrower than distal part
Females of the Campsomeris group in our area may be quickly separated based on the color of hair on the head (note: not the pronotal collar, which could cause confusion with Dielis plumipes). This trait is not typically useful with males. — J. Hoskins
Dielis: white hairs
Pygodasis: black hairs
Xanthocampsomeris: reddish-brown hairs
Range
Cosmopolitan below about 51°N latitude.
Remarks
Campsomeris (sensu stricto) is a Neotropical genus and does not occur in our area.
