Calozodion Moyas, A New Metapseudid Species (Crustacea: Tanaidacea: Apseudomorpha) from the Moroccan Atlantic Coast

Abstract

A new apseudomorph tanaidacean species, Calozodion moyas sp. nov., from the Moroccan Atlantic waters is described. The new species is the third species of the genus Calozodion Gardiner, 1973 known in the western African coasts and the tenth in the worldwide fauna. The main features by which the new species differs from all others of the genus Calozodion consist in the presence of a mediodorsale process at the basis of pereopod 2 (absent in C. bacescui Guţu, 1996, C. dollfusi Guţu, 1989, C. heardi Guţu, 2002, C. multispinosum Guţu, 1984 and C. singularis Guţu, 2002) and of five long setae on the first article of mandible palp (comparatively to at most three setae in the species C. dominiki Bochert, 2012, C. simile Guţu, 2006, C. suluk Bamber & Sheader, 2005 and C. wadei Gardiner, 1973). Other differences result from the identification key of the species of the genus Calozodion presented in the final part of this paper.
