A white small species. Carapace cylindrical without any grooves or spines, except for usual antennal and pterygostomial spines. Rostrum about twice as long as carapace, curving obliquely upward at basal one-fourth; upper margin with a three-or four-toothed crest at level of bottom of orbit, and usually with a subterminal small spine; lower margin with six equidistant spines, and with a fringe of plumose hairs at its basal part to first spine. Pereiopods markedly slender, and first two pairs chelate, second pair being slightly stouter than the others; in second pair merus bulged basally, carpus widening distally, and palm as thick as basal part of merus and half as long as fingers.
Distribution:
West Atlantic from Venezuela to northeast coast of Brazil, 5-75 m deep.
Remarks:
General appearance of the carapace and rostrum is unexpectedly close to Xiphopenaeus kroyeri (Heller) of the Penaeidae and Exhippolysmata oplophoroides (Holthuis) of the Hippolytidae, which are distributed in the same localities and used as food in the same way as this species.
