Remarks. The first record of C. filosa in the Persian Gulf is referred by Jones (1986) from the Kuwait waters, which was recently reported by Myers & Nithindaranan (2016) from the Kuwait coasts. They mentioned that the material agrees well with the Mediterranean material that was described by Peart (2004). The material of the present study from the northern coasts of the Persian Gulf differs in some characters. The third article of mandibular palp is the longest in the Persian Gulf material, but in Peart’s (2004) studied material the second article is the longest. Also the first coxa in the present material is produced anteriorly and the dactylus in second male gnathopod is shorter, not reaching the end of palm. The present studied material was collected from Padina algae on silky cover.
