The article cites a study which examines the presence of the pontoniine shrimp or tuleariocaris holthuision the pacific coast of Panama. It investigated that it female species were investigated in the Coiba National Park which confirmed its presence in the region and significantly increasing. They were found attached to the spines of a black sea urchin, which is their only known host in the eastern pacific. It also determined that they include four species all associated with sea urchins, including Tuleariocaris holthuisi, Tuleariocaris Neglecta, Tuleariocaris sarec and Tuleariocaris Zanzibaricu.

The present paper reports 13 species of shrimp from Dongtou Island, Zhejiang Province, in the East China Sea. Among these, a species of alpheid, Alpheus euphrosyne De Man, 1897, which is very similar to the typical subspecies, is recorded for the first time from Chinese waters; one species of penaeid, Metapenaeus affinis (H. Milne Edwards, 1837), is recorded for the first time from Zhejiang; and six other species are recorded for the first time from Dongtou Island with certainty. [ABSTRACT FROM AUTHOR]

The diet composition of the pandalid shrimp, Plesionika narval was determined, based on an analysis of two samples of 250 specimens each, collected in March and August 2004, respectively, in the Aegean Sea. Plesionika narval displayed a diversified diet, mainly based on Crustacea. The vacuity coefficient values and the stomach fullness percentages indicated a higher feeding activity of this species in March than in August. This is probably due to the accumulation of energy resources for the spawning period in March. P. narval seems to be an active predator but also an occasional scavenger, utilizing a wide variety of benthic resources. Multidimensional analyses demonstrated that the diets of P. narval in March and August were significantly different. Moreover, no significant differences were observed in the diet composition of males and females in the two groups of specimens studied. [ABSTRACT FROM AUTHOR]

A new caridean shrimp belonging to the genus Eualus Thallwitz, 1891 (Decapoda, Caridea, Hippolytidae) is described on the basis of specimens from the south-eastern Australian continental shelf. Eualus pectiniformis sp. nov. can be distinguished from its congeners in having a combination of: a short rostrum bearing three dorsal teeth and either none, or a single ventral tooth, a rounded pterygostomial angle, epipods on the maxillipeds as well as on the anterior three pereopods, merus of third to fourth pereopods of males possessing a row of comb-like spines on the distoventral margin, and the dactyli of the ambulatory legs armed with 5 spines on the posterior margin next to the apical spine. A rare hippolytid species, Lysmata morelandi (Yaldwyn, 1971) is also recorded for the first time in Australian waters. [ABSTRACT FROM AUTHOR]

Two new species of Synalpheus Bate, 1888 are described for the Gulf of California, Mexico, in the eastern Pacific. Synalpheus wickstenae new species, and S. stylopleuron new species, belong to the paulsoni group as defined by Coutière (1909) and are morphologically closest to S. sanjosei Coutière, 1909, and S. superus Abele & Kim, 1989. These new species are distinguished by a series of characters mostly related with the shape and position of rostrum and occular teeth, the relative length and length/width ratio of the rostrum, the proportion between cephalic appendages, the presence/absence of a dorsal spine on the palm of the minor cheliped, the proportion of dactylus and propodus of the third pereiopods, and the shape of the first abdominal pleura in males.
