From the Greek cephale (head) and gyne (female), alluding to the head of the female which is larger than in the male ("very large head, notably larger in the female than in the male") [feminine].

Diversity.

Twenty-two species in the Nearctic (14 species, of which two extends into the Baja California Peninsula and one is adventive) and Palaearctic (nine species, including the Himalayas) Regions.

Identification.

Noonan (1996) revised all the species. One Palaearctic species, Anisodactylus emarginatus Ito, has been described subsequently. Lindroth’s key (1968: 835-838) included all North American species except Anisodactylus pseudagricola described subsequently.
