Palaemonoid shrimps from the Dampier Archipelago (Crustacea: Decapoda), with a review of the Western Australian pontoniine shrimp fauna A.J. Bruce Queensland Museum, 1'.0. Box 3300, South Brisbane, Queensland, 4lO1 Australia. email: abrucet...lJroad.net.au Abstract. - Palaemonoid shrimps collected in the course of the Western Australian Museum 1998-2002 Dampier Archipelago Survey arc reported upon. Thirty one taxa were found, all except three belonging to the subfamily Pontoniinae. One species of pontoniine shrimp is new: Periclimenes burrup sp. novo is described and illustrated, and seven are new to the Western Australian fauna. The pontoniine shrimp fauna of Western Australia is summarised. INTRODUCTION the pontoniine shrimps now known from Western The marine palaemonoid fauna of Western Australia is provided and the results are Australia has attracted less attention than that of summarised in Table 1. Australia's eastern seabord. The fauna is dominated Many more pontoniine (and other) shrimp species by shrimps of the subfamily Pontoniinae, usually may be expected to be found in the future in small, often cryptic, and frequently inconspicuous Western Australian waters. The present total may associates of other marine invertebrate hosts, be compared with that of a single small reef on the particularly sponges, coelenterates, echinoderms southern Great Barrier Reef, Heron I., with over 100 and sea squirts. species (Bruce, 1981).
