Introduction

Processid shrimps are often found on shallow seagrass flats and tide pools, although some occur as deep as 566 metres. Five genera and about 60 species are recognised worldwide. They are distributed in all tropical and subtropical seas, but are apparently absent from the west coast of South America; one genus, Ambidexter, occurs only in the shallow tropical American Atlantic and eastern Pacific. Three genera and 12 species are now recorded from Australia (2012), most having wide Indo-west Pacific distributions and only one, the temperate Processa gracilis Baker, 1907, being restricted to Australian waters. Chace (1997) included a key to the five processid genera. Earlier important revisionary studies with keys to species are those of Hayashi (1975) and Noël (1986).

Diagnosis

Rostrum a discrete structure inflexibly attached to remainder of carapace, unarmed except (usually) for pair of teeth delimiting terminal seta-filled notch. Carapace without longitudinal lateral ridges, complete postantennal suture, or cardiac notch. Telson bearing two pairs of posterior marginal spines and one or more pairs of mesial setae. Eyestalks normal, neither abnormally long nor concealed beneath carapace. Antennule with two completely separate flagella, neither with accessory branch. Mandible without palp or incisor process, latter obliquely truncate, sometimes slightly flared. Second maxilla with endite reduced, scaphognathite with proximal lobe produced only moderately into branchial cavity. First maxilliped with exopod abutting endite and displacing palp out of plane, exopod without partially detached lobe, lash well developed, caridean lobe not much produced distally, not distinctly overreaching endite. Second maxilliped with exopod, endopod 4-segmented, not terminating in two segments attached side by side to preceding segment, terminal segment narrow strip attached obliquely to wide penultimate segment. Third maxilliped with exopod, 5-segmented, slender, pereiopod-like, antepenultimate segment fused with next proximal segment. Pereiopods without epipods, anterior pair more robust than second pair, often asymmetrical, second pair equal, with undivided carpus, fixed finger not curving subrectangularly around short, broad movable finger, fingers not concealed in dense setae. Third pereiopod with dactyl simple, unarmed on flexor margin. First pleopod of male with endopod laminar, not unusually large or elaborately convoluted. (After Chace 1997).
