Tribe Campsomerini

Older literature treated this group as a subfamily, Campsomerinae, variably sub-divided into 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).(1)

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.(2)

Separated from Scoliini by 2 veins at posterior margin of submarginal cell(3) forming a narrow, L-shaped enclosure

Overview of Genera

Females 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
