title: Redescription of poorly known species of Ceratothoa Dana, 1852 (Crustacea, Isopoda, Cymothoidae), based on original type material.
abstract: Due to the difficulty in accurately identifying cymothoids, these parasitic isopods are often incorrectly named or confused with other species. Within the genus Ceratothoa, a number of recent studies have aimed at clarifying some of the problematic species; however, several of the less studied species still require revision. This paper redescribes, from type material, several poorly known Ceratothoa species including Ceratothoa angulata, Ceratothoa capri, Ceratothoa carinata, Ceratothoa collaris, Ceratothoa gilberti, Ceratothoa gobii, Ceratothoa guttata, Ceratothoa italica, Ceratothoa oestroides, and Ceratothoa verrucosa, further resolving taxonomic uncertainties within the genus.
