ON THE OCCURRENCE OF TWO BRACHYURANS, MYRA SUBGRANULATA AND HERBSTIA CONDYLIATA, ON RHODES ISLAND (SE AEGEAN SEA) BY MARIA CORSINI 1,2 ) and GERASIMOS KONDILATOS 1 ) 1 ) Hellenic Center for Marine Research/Hydrobiological Station of Rhodes, Cos Street, GR-85100 Rhodes, Greece ABSTRACT Two brachyurans, the Erythrean Myra subgranulata (Leucosiidae) and the Atlanto-Mediterranean Herbstia condyliata (Majidae), were collected from the NE coast of Rhodes Island. The first species’ occurrence represents a new record for Greek waters and is the result of a gradual westward extension of its distribution along the eastern Mediterranean coasts, after its immigration from the Red Sea via the Suez Canal. The second species’ record is new for Rhodes. RÉSUMÉ Deux crabes brachyoures, l’érythréen Myra subgranulata (Leucosiidae) et l’atlanto-méditerra- néen Herbstia condyliata (Majidae) ont été récoltés sur la côte nord-orientale de l’île de Rhodes. La présence de la première espèce représente une nouvelle citation pour les eaux grecques et est le résultat de l’extension graduelle de sa répartition vers l’ouest le long des côtes méditerranéennes, après son immigration depuis la mer Rouge via le canal de Suez. La seconde espèce est nouvelle pour Rhodes. INTRODUCTION Recent investigations conducted in the sublittoral zone of the island of Rhodes have enlarged the number of decapod crustacean species to 83, and the sto- matopods recorded in the area to three (Kevrekidis & Galil, 2003). Among these are six decapods and one stomatopod of Indo-Pacific origin. Successive records of the portunids, Portunus pelagicus (Linnaeus, 1758) and Bathynectes longipes (Risso, 1816) have increased the number of decapods known from the island to 85 (Corsini Foka et al., 2004). 2 ) e-mail: mcorsini-foka@hsr-ncmr.gr © Koninklijke Brill NV, Leiden, 2006 Crustaceana 79 (2): 167-174 Also available online: www.brill.nl
