Abstract -- Forty-seven species of alpheid 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" annjJlatlls" subdivision of the Alphells edwardsh species group.

INTRODUCTION development. The diverse genera in the family Snapping shrimp (family Alpheidae) are common suggest numerous adaptations to different habitats. inhabitants of intertidal and shallow subtidal areas In the speciose genera Alphel1s and Synalphel1s, in temperate and tropical waters world-wide. Also subspecific morphological groups have been known as pistol shrimps, these benthic proposed, but as yet no thorough syntheses of these are characterized by having large chelate first taxa have been attempted, nor have morphometric pereopods, multi-articulate second pereopods and analyses or molecular phylogenetic studies been a distinct cardiac notch on the posterolateral margin attempted for most species. Recent work by of the carapace. Despite the common name, many Knowlton and Mills (1992) has found crypti'c species do not produce a snapping sound.
