Genus PSEUDOCLETODES S'ars. New name. SARSOCLETODES. 



Pseudocletodes G. O. Sars, The Crustacea of Norway, vol. 7, 1920, Copepoda 

 Supplement, p. 89. 



Type of genus, Pseudocletodes typicus, monotypic. 



T. and A. Scott established in Annals and Magazine of Natural History (ser. 

 6, vol. 12, 1893, p. 237), a new genus and species, Pseudocletodes vararensis. 

 The two genera are distinct and hence the genus name of Sars' species must be 

 changed.
