Introduction The presence of the pontoniine shrimp genus Periclimenaeus Borradaile, 1915, in Australian waters was established by E.J. Miers (1884) when he described Coralliocaris ? tridentatus (now Periclimenaeus tridentatus), from Thursday Island, Torres Strait, Queensland, in his report on the crustaceans collected, by Dr R.W. Coppinger, Staff- Surgeon during the Indo-Pacific Surveying Voyage of H.M.S. Alert, 1881-2. A second species, Coralliocaris hecate Nobili, 1904 (now Periclimenaeus hecate) was reported from Cape Jaubert, Western Australia by Heinrich Balss (1921), reporting on the material of Dr E Mjöberg’s Swedish Scientific Expedition to Australia (1910–1913). Periclimenaeus currently contains 45 species in the Indo-West Pacific region and is the second largest genus in the Pontoniinae. At least 22 species are reported to occur in Australian waters and 13 species have been previously recorded from Queensland, particularly from the coral reefs of the Great Barrier Reef. The species of Periclimenaeus are associates of sponges and ascidians, although the Accepted by J. Goy: 20 Apr. 2006; published: 5 Jun. 2006 1.

DE GRAVE* Abstract A report is presented on a small collection of caridean shrimp (Crustacea: Decapoda) from coastal waters of the United Arab Emirates in the Persian Gulf. Eight species are new records for the area, raising the total number of carideans known from the Persian Gulf to 46. A review is presented of all previous records, which highlights the relative paucity of records.

J. BRUCE Crustacea Section, Queensland Museum, P. O. Box 3300, South Brisbane, Queensland, Australia 4101. E-mail: [email protected]. Abstract Recent collections of pontoniine shrimps from Heron Island, southern Great Barrier Reef, have provided further additions to the Australian marine fauna. A new species, Periclimenes poriphilus sp. nov., is described and illustrated. It is the first species of its genus to be found actually in a sponge host. Several other Periclimenes species have been reported as associates of sponges. Periclimenaeus arthrodactylus Holthuis, 1952, is reported for the second time only, previously known only from a single specimen collected in the Pulau Sailus Ketjil, Java Sea, Indonesia, in 1899, and new to the Australian fauna. Further specimens of Typton wasini Bruce, 1977 are recorded and Typton nanus Bruce, 1987 is re-assessed as a junior synonym of T. wasini, having been based on a juvenile specimen. An up-dated checklist of the Heron Island pontoniine fauna is also provided.

Box 4646, Dxwin, Australia 0801 ABSTRACT A collection of palaemonoid shrimps from New Caledonian waters less than 100 m depth has been examined and found to include 39 species, including three new species, Palemonella dolichodactylus, Periclimenes ischiospìnusus and P. tenuirostris, and fourteen species new to the New Caledonian fauna, increasing to 67 the number of marine palaemonoid shrimps known from New Caledonia. RESUME Une collection de crevettes palaemonides trouvees dans les eaux de moins de 100 m de profondeur en Nouvelle-Cal6donie a CtC examinee et 39 espèces ont Ct6 identifiees, trois d'entres elles sont nouvelles pour la science, Palaemonella dolichodactylus, Periclimenes ischiospinosus, P. tenuirostris, et quatorze espèces sont nouvelles pour la faune de Nouvelle-Caledonie. Le nombre des espèces de crevettes palaemonides marines est maintenant port6 h soixante-sept. La zoogeographie de ces espèces est brièvement diScutCe. INTRODUCTION The marine palaemonoid shrimps of New Caledonia have not attracted a great deal of study. Early collections were made by Abbe CULLIERETin 1890 and deposited in the collections of the Museum national d'Histoire naturelle, Paris, some of which were reported upon by KEMP (1922). HOLTHUIs (1953) recorded the presence of Stegopontonia commensalis. BRUCE (1968, 1970 a, 1970 c) added nine further species to the New Caledonian fauna list and more recently a series of papers by MONOD (1969,1972,1973,1976 a, 1976 b) provided data on a further nine species.

    HOLTHUISAEUS, A NEW GENUS FOR PERICLIMENES (PERICLIMENAEUS) BERMUDENSIS ARMSTRONG, 1940 (DECAPODA, PALAEMONIDAE, PONTONIINAE) BY ARTHUR ANKER1,3) and SAMMY DE GRAVE2,4) 1) Florida Museum of Natural History, University of Florida, Gainesville, FL 32611-7800, U.S.A. 2) Oxford University Museum of Natural History, Parks Road, Oxford, OX1 3PW, United Kingdom ABSTRACT A new pontoniine genus, Holthuisaeus gen. nov., is established for the western Atlantic sponge-dwelling shrimp species, Periclimenes (Periclimenaeus) bermudensis Armstrong, 1940. The new genus appears to be related to three other genera containing sponge-dwelling species, Periclimenaeus Borradaile, 1915, Climeniperaeus Bruce, 1994, and Paraclimenaeus Bruce, 1988, sharing with them the presence of a fossa-molar process mechanism on the chela of the major second pereiopod. However, the combination of the plunger being situated on the fixed finger and the fossa on the dactylus, the carpus of the second pereiopods dorsally excavated and bearing a strong process, the vestigial mandibular incisor process, the presence of a short process on the fourth thoracic sternite, and the absence of an appendix masculina on the male second pleopod separates Holthuisaeus from all other pontoniine genera. RÉSUMÉ Holthuisaeus gen. nov., un nouveau genre des crevettes pontoniinées, est établi pour Per- iclimenes (Periclimenaeus) bermudensis Armstrong, 1940, une espèce de l’Océan Atlantique Occidental associée aux éponges. Le nouveau genre semble être apparenté aux trois autres genres contenant des espèces spongicoles, Periclimenaeus Borradaile, 1915, Climeniperaeus Bruce, 1994, et Paraclimenaeus Bruce, 1988, partageant avec ces derniers la présence d’un sys- tème dent-cavité sur la pince du grand chelipède.

E-mail: [email protected] 3 Marine Science Station, Aqaba, Jordan. E-mail: [email protected] 4Faculty of Marine Sciences, University of Jordan, Aqaba, Jordan Abstract A new species of sponge-associated pontoniine shrimp from the northeastern Red Sea is described and illustrated. The new species is closely related to Periclimenaeus rhodope, but can be easily distinguished from the latter by the dense spinulation of the second pereiopod chelae. The new species is placed in the Periclimenaeus robustus species group, on account of the presence of the anterodorsal median lobe on the first abdominal segment. The new species is the first rep- resentative of the genus reported from a discrete Red Sea locality. Key words: Crustacea, Decapoda, Pontoniinae, Periclimenaeus echinimanus new species, Red Sea, sponge symbiont Introduction The majority of species of the genus Periclimenaeus are known as obligatory commensals of sponges or ascidians (Bruce, 2006a). Recent studies of sponges have revealed the presence of previously unreported small and incon- spicuous, often highly cryptic, representatives of this genus (Bruce, 2006a,b; Marin, 2007; Ďuriš et al., 2009a,b).
