Abstract	Forty-seven species of alpheid shrimp were collected bv the Dampier Archipelago Expedition in 1998-2002. Six species are report(;d for the tIrst tIme from northwestern Australia. The majority of the positively id~'ntified species (18, or 40'X,) range widely from the western Indian Ocea;) and Red Sea to the central Pacific Ocean. Seventeen species (38%) range from the western Indian Ocean into the western Pacific, six species (13%) range trom the eastern Indian Ocean into the western Pacific, and 4 (9'/0) range into the eastern Pacific. Three species of commensal shrimp were collected from corals and crinoids. Two species are strictly intertidal, 11 are strictly subtidal and 32 range from the lowest intertidai zone to subtidal depths. The majority of the shrimp inhabit areas of rocks, coral, shell or rubble, but A/pheus rapacida De Man, 1908 and A serenej Tiwari, 1963 typically live in sandy or muddy areas. We follow the systematic treatment of Chace (1988) and BaJ~ner and B,;nner (1973; 1975; 1982) 'for alpheids, but use a new subdivision, the" Alpheus annjJlatlls" subdivision of the Alphells edwardsh species group. INTRODUCTION Snapping shrimp (family Alpheidae) are common inhabitants of intertidal and shallow subtidal areas in temperate and tropical waters world-wide. Also known as pistol shrimps, these benthic crustaceans are characterized by having large chelate first pereopods, multi-articulate second pereopods and a distinct cardiac notch on the posterolateral margin of the carapace. Despite the common name, many species do not produce a snapping sound. ' The taxonomy of snapping shrimps generally follows the pioneering work of CoubE:re (1899; 1905; 1908; 19(9). The most recent comprehensive works on alpheid shrimps of the Indo-Pacific area are those of Banner and Banner (1973; 1975; 1982) and Chace (1988). Davie (2002) compiled a check list of alpheid species known at the time from Australia. These works provide detailed synonymies, keys and illustrations. Holthuis (1993) provided an illustrated key to all of the "enera of . b al pheids known to the date of publication. Systelnatics of the Alpheidae has received less attention. Christoffersen (1987) supported the monophyly of the family. Banner and Banner (1973) considered as "lower" all alpheid genera lacking large chela of "excessive" size and asymmetrical development. The diverse genera in the family suggest numerous adaptations to different habitats. In the speciose genera Alphel1s and Synalphel1s, subspecific morphological groups have been proposed, but as yet no thorough syntheses of these taxa have been attempted, nor have morphometric analyses or molecular phylogenetic studies been attempted for most species. Recent work by Knowlton and Mills (1992) has found crypti'c species, very similar in morphology but recognizable by colour patterns and geographic distribution. Williams et al. (2001) used nuclear and mitochondrial sequence data to suggest three major c1ades within the genus Alphel1s, which combine several of the traditional informal morphological groups. \Ve use an arrangement of genera similar to that presented in the key by Chace (1988). MATERIALS AND METHODS In this work, we provide an account of each species identified from the specimens taken by the 1998-2002 expeditions to the Dampier Archip~lago by the \Vestern Australian Museum.
