Introduction

Stylodactylid shrimps are found in depths from 3 to 3515 metres. They are most speciose in the tropical and subtropical Indo-west Pacific Ocean from eastern Africa to Hawaii, but extend northward to the Korea Strait, and southward to South Africa and around the Kermadec Islands. They also occur in the western Atlantic (Florida Straits, Bahamas, Yucatan Channel, Haiti, Lesser Antilles), and in the eastern Atlantic off Spanish Sahara and Canary Islands) (Chace 1983; Cléva 1990b). There are five genera, all of which are found in Australian waters (Cléva 1990a, 1994). Holthuis (1993: 85) and Hanamura & Takeda (1996: 930) provided keys to genera.

Diagnosis

Rostrum nearly as long as or longer than remainder of carapace and immovably attached to it; eyes well developed, freely movable; antennular flagella simple, undivided; mandible with molar and incisor processes not deeply separated; second maxilliped with two distal segments arising, side by side, from preceding segment; third maxilliped and two anterior pairs of pereiopods longer than three posterior pairs of pereiopods, without exopods, fringed with remarkably long setae; two anterior pairs of pereiopods subequal in length, similarly slender, with elongate and virtually unarmed fingers, movable finger nearly as long as fixed finger, palm much reduced, carpus entire, not subdivided; three posterior pairs of pereiopods with carpus distinctly shorter than propodus. (After Chace 1983).
