Type species.

Remarks.

Diagnostic characters for Ceratothoa include the contiguous and swollen antennular bases, triangular cephalon, and the elongate body (2.1-2.9 times as long as wide). Ceratothoa also has a pleotelson and pleonite 1 which are narrower than the other pleonites, and subequal uropod rami which do not extend past the pleotelson. A full diagnosis of the genus is provided by Hadfield et al. (2014b).
