Revision of the genus Ctenophilothis Kryzhanovskij, 1987 (Coleoptera: Histeridae: Saprininae).

The Saharan genus Ctenophilothis Kryzhanovskij, 1987 is revised. Its two species, C. chobauti (Th6ry, 1900) and C. altus (Lewis, 1885), differ mainly by the shape of their mandibles, protibia, and elytral striae. Ctenophilothis is likely a monophyletic genus known so far only from the Algerian, Moroccan, and Egyptian Sahara. The neotype of C. chobauti and lectotype of C. altus are designated. The extremely rare C. altus is redescribed and both species are illustrated by SEM micrographs. The male genitalia of C. chobauti are also illustrated.
