Camedula Motschulsky, 1865: 303 (type: glabratum Dejean, 1831)
Carabosoma Géhin, 1885: 32 (type:glabratum Dejean, 1831)
Acamegonia Lapouge, 1924: 38 (type: peregrinatrix incerta Lapouge, 1924 = C. sponsa Casey, 1897)
Camegonia Lapouge, 1924: 38 (in litteris)
Camegonia Breuning, 1927: 94 (type: prominens LeConte, 1853)

According to Jeannel (1940), Camedula and Callitropa, that occupy Central America and southern United States, belong to a single phyletic line and are phylogenetically related to South American Castrida from which differ in the chaetotaxy and in particular for having lost the brush on the male's mesotibiae. In the same lineage would also have evoluted the species of wingless mountain Calosoma, collected in the subgenera Carabomimus and Calopachys, that are limited to Mexico. The species collected in Camedula differ from the other of the same phyletic line because the margin of the elytra is with evident serration and because the rear angles of the pronotum are characteristically reduced, although still distinguishable. Jeannel has dealt with Camedula as a distinct genus. Furthermore inside Camedula he distinguished the subgenus Camegonia, without setae on the metatrochanters, and the subgenus Carabosoma with a strongly angular sided pronotum and elongated and parallel elytra.
