Introduction

This family of deep water pelagic shrimps comprises a single genus Bathypalaemonella, found in all tropical seas between latitudes 27ºN and 13ºS, and from 308–1463 metres depth (Chace 1997). A key to the eight described species was provided by Bruce (1986: 263).

Diagnosis

Rostrum discrete, slender, elongate, with varying numbers of teeth and articulated spines dorsally, extending onto anterior carapace. Carapace without longitudinal lateral ridges, postantennal suture, or cardiac notch. Eyestalks normal, neither unusually long nor concealed beneath carapace. Antennule with two completely separate flagella, neither with accessory branch. Mandible with palp, with molar and incisor processes not deeply divided, molar process subtruncate, with transversely ridged grinding surface, not flared. Second maxilla with endite normal, scaphognathite rounded proximally, not deeply produced into branchial cavity. First maxilliped with epipod not abutting endite, not displacing palp out of line, exopod without partially detached lobe, lash well developed, caridean lobe not much produced distally, but distinctly overreaching endite. Second maxilliped with exopod, endopod composed of four segments, not terminating in two segments attached side by side to preceding segment, terminal segment attached obliquely to penultimate segment. Third maxilliped with exopod, 5-segmented, slender, pereiopod-like, antepenultimate segment fused with next proximal segment. Pereiopods without exopods, epipods, if present, not terminating in naked appendix extending vertically into branchial chamber, with arthrobranchs on four anterior pairs. Anterior pair subequal, slender, with one movable and one fixed finger. Second pair very unequal; carried flexed beneath thoracic sternites, with unique locking mechanism; fixed finger not curving subrectangularly around movable finger, carpus entire, undivided. Third pereiopod with dactyl spinose on flexor margin. First pleopod of male with endopod laminar, not unusually large or elaborately convoluted. (Modified after Chace 1997).
