Third and fourth pereiopods with spiniform setae on ventrolateral surface of ischium; merus armed with distal tooth on ventral margin; carpus unarmed, with half length of merus; propodus with seven spiniform setae on ventral margin plus pair of distoventral spiniform setae near articulation with dactylus; dactylus about 1/3 length of propodus, simple, gradually curved towards sharp tip (Figs. 2F, G). Fifth pereiopod with ischium and merus unarmed; carpus armed with distoventral tooth, about half length of merus; propodus slightly longer than carpus with six spiniform setae on ventral margin plus pair of distoventral setae near articulation with dactylus; dactylus simple, about 1/3 length of propodus, slightly curved, distally sharp (Fig. 2H).</p><p>Variation. There was no consistent morphological variation in the characters analyzed for all western and eastern Atlantic specimens.
