Two new species of the alpheid genus Athanas Leach, 1814 are described and illustrated. Athanas sydneyensis n. sp., is described on the basis of several specimens collected near Sydney, New South Wales, Australia. This species is closely related to the polymorphic A. phyllocheles Banner & Banner, 1983 known only from La Reunion in the southwestern Indian Ocean. Athanas ivoiriensis n. sp., is de...

Alpheopsis balaeniceps sp. nov. is described based on a single male specimen from Moorea, French Polynesia. The new species is unique within the genus Alpheopsis Coutière, 1896 in possessing balaeniceps-type setae on the fingers of both chelipeds, being especially well developed on the major chela. Within the family Alpheidae, this feature exists only in some species of the distantly related ge...

A new species of the alpheid shrimp genus Potamalpheops Powell, 1979, P. tyrymembe sp. n., is described based on several specimens collected from burrows of the ucidid crab Ucides cordatus (Linnaeus, 1763) and other, unknown burrowing decapods, on a mangrove flat between the Baiano and Serra rivers, Povoado de Tremembé, Maraú, state of Bahia, Brazil (14º08'51.9"S, 39º05'04.4"W). The new species...

Abstract:  This work was carried out to identify decapods of the Bushehr interidal zone, northern coast of the Persian Gulf. Specimens were collected from eight stations along the coast. During this survey, twelve species were identified, including one alpheid shrimp (Alpheus lobidens), three Anomura (Petrolisthes rufescens, Porcellana persica, Clibanarius signatus) and eight Brachyura (Portunu...

Despite the ubiquity of obligate mutualisms on coral reef ecosystems, little is known about the evolution of many participating species. The shrimp gobies, known primarily from the coral reef habitats of the Indo-Pacific, are small benthic fishes that participate in a remarkable mutualism with alpheid shrimp. In this mutualism, the shrimp build and maintain a burrow that is guarded by the goby,...

A new species of the alpheid shrimp genus Salmoneus Holthuis, 1955, S. antricola n. sp., is described and illustrated on the basis of a single ovigerous specimen from an aphotic marine cave at a depth of 12 m, off Ie Island, Okinawa Islands, the Ryukyu Archipelago. It is morphologically similar to five species presently referred to the S. jarli (Holthuis, 1951) species group: S. erasimorum Dwor...
