CALOZODION MOYAS, A NEW METAPSEUDID SPECIES (CRUSTACEA: : APSEUDOMORPHA) FROM THE MOROCCAN ATLANTIC COAST

MOHAMED MENIOUI

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.

Résumé. Une nouvelle espèce, Tanaidacé Apsedomorphe, Calozodion moyas sp. nov., est décrite des eaux atlantiques marocaines. C’est la troisième espèce du genre Calozodion Gardinier, 1973 connue des côtes de l’Afrique de l’Ouest et la dixième à l’échelle planétaire. Les principaux caractères par lesquels cette espèce diffère de toutes les autres espèces du genre Calozodion consistent en la présence d’une excroissance médiodorsale au niveau du basis du pereopode 2 (absente chez C. bacescui Guţu, 1996, C. dollfusi Guţu, 1989, C. heardi Guţu, 2002, C. multispinosum Guţu, 1984 et C. singularis Guţu, 2002) et de cinq longues soies sur le premier article du palpe mandibulaire (comparativement à, au plus, trois soies chez les espèces C. dominiki Bochert, 2012, C. simile Guţu, 2006, C. suluk Bamber & Sheader, 2005 et C. wadei Gardiner, 1973). D’autres différences sont exprimées dans la clé d’identification des espèces du genre Calozodion présentée dans la partie finale de ce document.

Key words: Tanaidacea, Apseudomorpha, Metapseudidae, Morocco, Calozodion moyas sp. nov.

INTRODUCTION Tanaidaceans are still unknown in Morocco, as well as in many other marine areas. The only papers regarding these crustaceans are Monod (1925 a, b), Tattersal (1925) and Menioui (1988, 1997). In my study area, I identified a new species of the genus Calozodion Gardiner, 1973, associated with two other species (Chondropodus curvispinus Guţu, 2006 and Plectrocopus spicatus Guţu, 2006) reported previously from the Mauritanian coast (Guţu, 2006). In this paper, I present an identification key and a formal description of the new species Calozodion moyas sp. nov. The used terminology follows Larsen (2003). The new species lives within the environment of Cintra Bay (southern Morocco), an area particularly interesting by its hydrological characteristics (). It is recorded in the subtidal zone at shallow water (about 6 meters) on a soft aphytic bottom, rich in shell debris. The biological material is collected using scuba diving, and each sample corresponds to an area of 1m2 of sediment, kept in a liquid consisting of 10% formalin and 90% seawater. It’s the first time that the genus Calozodion is identfied in the Moroccan coast, as well as two other genera (Chondropodus, Plectrocopus) described in the 10 MOHAMED MENIOUI Mauritanian coasts by Guţu (2006), suggesting a similarity between the study area (Cintra Bay) and the Mauritanian coasts.

SYSTEMATICS Family Metapseudidae Lang, 1973 Subfamily Chondropodinae Guţu, 2009 Genus Calozodion Gardiner, 1973

The genus Calozodion was described by Gardiner (1973) from the Caribbean Sea (Coast of Jamaica Island) based on a single female. Guţu, (1984) described for the first time the males of this genus. Subsequently Guţu (1989, 1996, 2002, 2006), Bamber & Sheader (2005) and Bochert (2012) described other species from different marine areas (Malaysia, Angola, Namibia, Brazilia, ). Calozodion codreanui, described from the Brazilian waters by Guţu, (1996), was transfered to the genus Vestigiramus (Guţu, 2008). Up to now, the genus Calozodion, classified in the subfamily Chondropodinae by Guţu, 2009, contains ten species including the new species Calozodion moyas sp. nov. described in this paper. The others nine species of this genus (Anderson, 2012, 2013) are the followings: C. bacescui Guţu, 1996, C. dollfusi Guţu, 1989, C. domniki Bochert, 2012, C. heardi Guţu, 2002, C. multispinosum Guţu, 1984, C. simile Guţu, 2006, C. singularis Guţu, 2002, C. suluk Bamber & Sheader, 2005 and C. wadei Gardiner, 1973.

Etymology: “moyas” mostly from the first letters of the member names of the author’s family, Mina and Myriem (m), Ouafae (o), El Yazid (y), Abderrahim (a) and Sarah (s), respectively. Remarks. Calozodion moyas sp. nov. has some resemblances with C. wadei from the Carribean Sea and C. simile from the Mauritanian coast, but differs mainly by: -- the outer margin of the first article of antennule with two denticles (as in C. wadei, but C. simile have 3-5 denticles); -- the inner side of the first article of antenna with one stout denticle C. ( wadei. and C. simile devoid of stout denticle); -- the antenna squama with six setae (three in C. wadei and four in C. simile); -- the palp of mandible with five setae on first articleC. ( wadei with two setae; C. simile with three setae); -- maxillule palp with three setae (C. wadei with two setae; unknown in C. simile); 16 MOHAMED MENIOUI -- female chelipedal carpus as long as wide, with one robust denticle (carpus of C. wadei 1.6 times longer than wide and with one small denticle; C. simile with two denticles); -- pereopod 1 with a tuft of some long setae on the midventral side of the merus (same in C. simile but C. wadei is without these setae); -- pereopod 4 with eleven ciliate setae on the propodus (C. wadei and C. simile with eight and fourteen setae, respectively); -- pereopod 6 with nineteen disto-ventral setae on the propodus (as in C. wadei but C. simile has twenty five setae).
