Taxonomic Decision for Synonymy
Introduction
This family of deep water shrimps comprises only a single genus and two very similar species. Eugonatonous chacei Chan & Yu, 1991 occurs in the Indo-West Pacific from Japan to northern Australia and eastwards to the Tonga Islands. Only recently, it was recognised as a distinct species, separate from E. crassus (A. Milne Edwards, 1881), which occurs in the Western Atlantic from off Georgia to Gulf of Mexico and Caribbean as far as Nicaragua and Grenada.
Diagnosis
Rostrum a discrete, grossly dentate extension of, and attached inflexibly to, remainder of carapace. Carapace with longitudinal lateral ridges, without longitudinal suture or cardiac notch in posterior margin. Eyes normal, neither unusually long nor concealed beneath carapace. Antennule with two flagella, neither with accessory branch. Mandible with 3-jointed palp, usually without incisor process, molar process subtruncate, not flared distally. Second maxilla with normal endite, scaphognathite only moderately produced proximally into branchial chamber. First maxilliped with exopod not abutting endite, not displacing palp out of plane, exopod without partially detached lobe, lash well developed, caridean lobe blunt, slightly produced, distinctly overreaching endite. Second maxilliped with exopod, endopod 4-segmented, not terminating in two segments attached side by side to preceding segment, terminal segment applied as a narrow strip to mesial margin of penultimate segment. Third maxilliped with exopod, composed of five segments, slender, pereiopod-like, antepenultimate segment fused with next proximal segment. Pereiopods with exopods on all five pairs, with strap-like epipods (mastigobranchs) on four anterior pairs without naked appendix extending vertically into branchial chamber, with arthrobranchs on three anterior pairs, two anterior pairs rather robust, fingers without terminal tuft of setae but bearing long lateral and terminal spines forming basket-like cage when closed, first pair subequal, stouter and shorter than second pair, with one fixed and one movable finger. Second pair of pereiopods subequal, fixed finger not curving subrectangularly around short, broad movable finger, carpus entire, undivided. Third pereiopod with flexor margin of dactyl spinose. First pleopod of male with endopod laminar, not large or elaborately convoluted. (After Chace 1997).
