oa Journal of the Entomological Society of Southern Africa - Notes on Siphonaptera
Ctenophthalmus is represented by a solitary species, calceatus, in South Africa, whereas the genus is very rich in Central Africa. One might infer from this that it is a tropical genus were it not that it is well represented in the Palaearctic Region. In South Africa calceatus is rare, but widely distributed. This distribution is largely confined to the eastern half of Southern Africa and it may be that it is high rainfall and not temperature that favours the genus.
