Alien freshwater fish parasites from South Africa: diversity, distribution, status and the way forward
Smit, Nico J.; Malherbe, Wynand; Hadfield, Kerry A. (Elsevier, 2017)The global translocation and introduction of freshwater fish into non-native regions has created the perfect opportunity for the co-introduction of their parasites. In a recent review on non-native freshwater fish introductions ... -
Ceratothoa retusa (Schiœdte & Meinert, 1883) (Isopoda, Cymothoidae), a variable species of fish parasitic marine isopod from the Indian Ocean
Hadfield, Kerry A.; Bruce, Niel L.; Szinetár, Csaba; Smit, Nico J. (Brill Academic Publishers, 2014)Ceratothoa retusa (Schiœdte & Meinert, 1883) is redescribed from the lectotype (here designated) collected from Mozambique, and the range is extended to include the Gulf of Suez in the Red Sea. Ceratothoa retusa is distinctive ... -
Elthusa nierstraszi nom. n., the replacement name for Elthusa parva (Nierstrasz, 1915), a junior secondary homonym of Elthusa parva (Richardson, 1910) (Isopoda, Cymothoidae)
Hadfield, Kerry A.; Bruce, Niel L.; Smit, Nico J. (Pensoft, 2016)The recent transfer of Elthusa parva (Richardson, 1910) from Ceratothoa created a homonymy with Elthusa parva (Nierstrasz, 1915). Elthusa parva (Richardson, 1910) has priority and Elthusa nierstraszi nom. n. is proposed ... -
Elthusa winstoni sp. n. (Isopoda, Cymothoidae), a new fish parasitic isopod from Hawaii
Hadfield, Kerry A.; Smit, Nico J.; Tuttle, Lillian J. (Pensoft, 2017)The new cymothoid species, Elthusa winstoni sp. n., a branchial parasite of fishes from the family Acanthuridae Bonaparte, 1835 in Hawaii, is described and figured. The female adults can be distinguished by the strongly ... -
New records of fish parasitic isopods of the gill-attaching genus Mothocya Costa, in Hope, 1851 from the Virgin Islands, Caribbean, with description of a new species
Hadfield, Kerry A.; Sikkel, Paul C.; Smit, Nico J. (Pensoft Publishers, 2014)Two species of Mothocya Costa, in Hope, 1851 are reported from the Virgin Islands. Mothocya xenobranchia Bruce, 1986 was collected from St. John Island from the gills of the Atlantic needlefish, Strongylura marina, which ... -
Redescription and molecular characterisation of the fish parasitic isopod Norileca indica (Milne Edwards, 1840) (Crustacea: Isopoda: Cymothoidae) with a key to the genus
Van der Wal, Serita; Smit, Nico J.; Hadfield, Kerry A. (Taylor & Francis, 2017)Norileca indica (Milne Edwards, 1840) is fully redescribed based on ovigerous females collected from Maputo Bay, Mozambique, from the branchial cavity of the fish host Selar crumenophthalmus Bloch, 1793. An identification ... -
Redescription of poorly known species of Ceratothoa Dana, 1852 (Crustacea, Isopoda, Cymothoidae), based on original type material
Hadfield, Kerry A.; Bruce, Niel L.; Smit, Nico J. (Pensoft, 2016)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 ... -
Redescription of the fish parasitic “tongue biter” Cymothoa rhina Schioedte & Meinert, 1884 (Crustacea: Isopoda: Cymothoidae) from Singapore
Bruce, Niel L.; Hadfield, Kerry A.; Martin, Melissa B.; Nowak, Barbara F. (National University of Singapore, 2016)Cymothoa rhina Schioedte & Meinert, 1884 is redescribed from specimens collected in Singapore, the female of which is designated as neotype. Adult female Cymothoa rhina can be identified by the acute anterior margin of ... -
Review of the fish parasitic genus Ceratothoa Dana, 1852 (Crustacea, Isopoda, Cymothoidae) from South Africa, including the description of two new species
Hadfield, Kerry A.; Bruce, Niel L.; Smit, Nico J. (Pensoft Publishers, 2014)The genus Ceratothoa Dana, 1852 is revised for South African waters and re-diagnosed. Ceratothoa retusa (Schioedte & Meinert, 1883) is recorded from the eastern coast, and Ceratothoa africanae sp. n. and C. famosa sp. n. ... -

Van der Wal, Serita; Smit, Nico J.; Hadfield, Kerry A. (Pensoft, 2019)The branchial-attaching cymothoid genus, Elthusa Schioedte & Meinert, 1884 is a genus with a world-wide distribution of 36 species, including the three species described here. Elthusa raynaudii (Milne Ed-wards, 1840) is ... -
Revision of the fish parasitic genus Pleopodias Richardson, 1910 (Isopoda, Cymothoidae), with the description of a new species and key to the genus
Hadfield, Kerry A.; Smit, Nico J. (Pensoft, 2017)The cymothoid genus, Pleopodias Richardson, 1910, is revised and a new species from South Africa is recorded. Pleopodias nielbrucei sp. n. can be distinguished by large eyes covering majority of the cephalon (almost in ... -
Understanding growth relationships of African cymothoid fish parasitic isopods using specimens from museum and field collections
Welicky, Rachel L.; Malherbe, Wynand; Hadfield, Kerry A.; Smit, Nico J. (Elsevier, 2019)Cymothoid isopods are a diverse group of ectoparasites of fish species, and are particularly conspicuous as they are large and attach to the body surface, mouth, and gill chamber of fish hosts. These parasites transition ...
