Issue
Iles (1960) reported 2 different morphs at the type locality when describing C. virginalis: the holotype and some paratypes are referred to as "kaduna", while some other paratypes are named "kajose". Both morphs appear to be valid species, C. virginalis therefor only refers to the "kaduna" morph, while "kajose" awaits formal description as a new species (Ref. 54524).
