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 C. angulata, C. capri, C. carinata, C. collaris, C. gilberti, C. gobii, C. guttata, C. italica, C. oestroides, and C. verrucosa, further resolving taxonomic uncertainties within the genus
