Caprella moradi sp. nov. is described from intertidal zone of the Gulf of Oman, Iran. This species is differentiated from the most similar species Caprella danilevskii (Czerniavski, 1868), by four rows of fine setae on the body surface and bears a curved anterior surface of propodus in the second male gnathopod.

A new caprellid amphipod, Caprella tavolarensis n. sp., is described based on specimens collected from a Posidonia oceanica seagrass meadow at the Tavolara-Punta Coda Cavallo Marine Protected Area (Sardinia, Mediterranean Sea). The species is close to Caprella liparotensis, but can be clearly distinguished by smaller size, presence of a short rostrum, body elongate and dorsally smooth, absence of serrate carina on the basis of gnathopod 2 and pereopods, mouthparts scarcely setose, absence of Wne setae on peduncle of antenna 1 and absence of swimming setae on antenna 2. The number of caprellid species reported from the Mediterranean Sea has increased from 23 (1993) to 41 (2010), consequently, further taxonomical studies should be addressed to properly estimate the total amphipod diversity in the Mediterranean Sea.

Two caprellid amphipod species namely; Pseudocaprellina pambanensis Sundara Raj, 1927 and Hemiaegina minuta Mayer, 1890, were recorded as a part of the amphipod fauna associated with macroalgae in the coast of Hurghada Red Sea. The re-description and illustrations of the two species are based on the examination of 4627 individuals, 88% of them were P. pambanensis and the rest were H. minuta. The two caprellid species were collected from six sites scattered over Hurghada coast and their distribution and abundance were investigated. ª 2013 Production and hosting by Elsevier B.V. on behalf of National Institute of Oceanography and Fisheries.

Seventeen species of caprellid amphipods have been recorded so far in the Gulf of Mexico. New distributional and habitat data are included for 12 species. Pseudaeginella biscaynensis has been recorded again in the Gulf of Mexico for the first time since it was originally described 45 years ago. New orphological information based on the development of Deutella mayeri and a redescription of Metaprotella hummelincki are also provided, along with a key for species identification and zoogeographical comments at the regional and global scales

The tropical western Atlantic caprellid Paracaprella pusilla Mayer, 1890 (Crustacea: Amphipoda: Caprellidae) is reported in the eastern Mediterranean for the first time. Individuals were collected in the southern coast of Israel associated with drifting colonies of the bryozoan Bugula neritina and with Bugula colonies attached to a submerged kurkar ridge. The species has been recorded previously from marinas in the western Mediterranean. This new record suggests that P. pusilla may also be present in other localities of the Mediterranean and represents the first non-native caprellid species for the coast of Israel.

Reviewing the literature on all the crustaceans parasitizing freshwater and marine fishes of Basrah province, Iraq indicated the presence of 74 crustacean taxa. Sixty-five taxa belonged to the class Maxillopoda while nine taxa belonged to the class Malacostraca. All these crustaceans were adults living on the external surface of their fish hosts while three taxa were reported as larvae. Fifty-five species of such crustaceans were recorded from marine localities, 11 from freshwater localities and the remaining were from both freshwater and marine localities. The total number of crustacean species recorded for each fish host species fluctuated from a minimum of one crustacean species in 31 fish hosts to a maximum of 15 crustacean species in Chelon subviridis only. Number of fish hosts reported for these crustaceans fluctuated from one host in case of 45 crustacean species to a maximum of 18 hosts in case of praniza larvae of Gnathia sp.
