查看更多>>摘要：Grapsoid crabs, together with ocypodoids, are the two most important groups of intertidal brachyurans in the Persian Gulf and the Gulf of Oman. In total, four families, nine genera and 12 species of grapsoids.are known from the region. Peris-esarma guttatum (A. Milne-Edwards, 1869), and Plagusia squamosa (Herbst, 1790), are only recorded from the Gulf of Oman; Grapsus granulosus H. Milne-Edwards, 1853, and Thalassograpsus harpax (Hilgendorf, 1892), are collected for the first time from the Persian Gulf. Chiromantes boulengeri (Caiman, 1920), Nanosesarma sarii Naderloo & Tiirkay, 2009, and Parasesarma persicum Naderloo & Schubart, 2010, are so far known only from the region.

Hemipholis elon-gata, a name which has been used in place of H. cordifera, is a nomen dubium that cannot unambiguously be assigned to any known speciesof brittle star. Evidence is presented that the genus Hemipholis presently comprises only H. cordifera and its geminate Eastern Pacific congener Hemipholis gracilis, and it is shown that the latter name has priority over Hemipholis affinis. Hemipholis gracilis and H cordifera are illustrated and'compared to show how mature individuals can be distinguished. However, small individuals of both species are extremely similar. The latitudinal distributions of H. cordifera and H. gracilis appear to be causally related to coastal water temperature, possibly in conjunction with divergent ocean currents, and the relatively broad range of H. cordifera compared to H. gracilis is attributed to its cold tolerance and to the influence of widespread warm-water boundary currents in the central Western Atlantic. As regards the two other congeners that have been described, Hemipholis wallichii is revealed to be a juvenile ophiuroid incertae sedis, and Hemipholis microdiscus was previously transferred to the Amphiuridaeand assigned the nomen novum, Amphiura microdis-coida.

These species were misplaced in Storena Walckenaer, 1805, a zodariid genus'that is endemic to Australia. Four species are here transferred to Mallinella Strand, 1906: Mallinella suavis (Thorell, 1895) comb, nov., M. exornata (Thorell, 1887) comb, nov., M.fronto (Thorell, 1887) comb, nov., and M. decorata (Thorell, 1885) comb. nov. Mallinella irrorata (Thorell, 1887) belongs to an undescribed genus of the subfamily Zodariinae. This study also gives a complete list of all Storena specimens examined and studied by Thorell which are now deposited in four European museums.
查看更多>>摘要：The morphology and infraciliature of a new brackish water pleurostomatid ciliate, Amphileptus salignus n. sp., collected from mangrove wetlands in southern China were investigated using pbservations of live cells and the protargol impregnation method.Amphileptus salignus can be separated from its congeners by its large cell size, the presence of 4 left and 24-29 right somatic kineties, two kinds of extrusomes, the number and location of contractile vacuoles, and its habitat.
