Subgenus Carabophanus Kolbe, 1895
Carabophanus Kolbe, 1895:57 (type caraboides Raffray, 1882 = raffrayi Farmaire, 1883)
Calister Reitter, 1896:41 (typ. raffrayi Farmaire, 1883)
According to Jeannel (1940: 64), the African wingless Calosoma, more linked to the mountain habitat of ground and grassland, belong to genera: Carabops, Orinodromus and Carabomorphus, and their origin can be traced back to the Castrida - Caminara phyletic line. They differ from the other Calosoma belonging to this line because the lack of serration on the margin of the elytra.
In his genus Orinodromus, divided into the subgenera Orinodromus, sensu stricto, Elgonites and Carabophanus, Jeannel had put togheter, because of their morphological characteristics, some species more advanced than those in Carabops. In fact they have smooth mandibles, and reduced metaepisterna without punctation, while the inner armature of their penis has a normally formed ligule, as in Carabops, although somewhat larger.
All the species of the plateau of Ethiopia have in common some characteristics, which led to the creation of the subgenre Carabophanus: ligule short, wide, triangular, the male's mesotibie strongly arched and with a side brush, rear lobes of the pronotum small but easily visible, without setae, elytra smooth or with the sculpture replaced by series of points.
We think that the genera of Jeannel should be mantained as subgenera and, given the constancy of these characteristics and the geographical isolation of this group of species, it seems justified to maintain the Carabophanus subgenus as distinct from the Orinodromus subgenus.
