DESCRIPTION

Dorsal surface of carapace minutely granulate, bearing perliform granules on branchial, gastric regions, and several aggregates of granules medially on mesogastric region. Hepatic region slightly tumescent. Branchio-cardiac grooves shallow. Front medially grooved. Anterior margin of epistome medially notched; anterior margin of efferent channel concave. Upper, lower margins of subhepatic facet granulate, granules on lower margin larger. Lateral margin of carapace posteriorly to subhepatic facet closely beaded, granules smaller posteriorly. Posterior margin straight in male, arcuate in female. Epimeral surface smooth; epimeral margin minutely beaded. Margins of external maxillipeds minutely granulate, exopod distally granulate, punctate. Sternum minutely granulate. Anterior margin of abdominal sulcus prominently granulate. Fused male abdominal segments 2-6 bearing granulate basal knobs laterally. Margins of fused abdominal segments in female granulate, prominently granulate areas basally. Cheliped merus 0.6 as long as carapace in male; its dorsal surface minutely granulate, anterior and posterior surfaces bearing perliform granules, diminishing in size posteriorly. Carpus with strip of granules on inner and upper margins. Upper and lower surfaces of propodus granulate, arcuate strip of granules medially on inner margin. Fingers fluted, granulate, granulation most prominent proximally on outer margins;

inner margins denticulate. Granulation in female specimens less prominent. Pereiopodal propodi dorsally and ventrally carinate, first pereiopodal propodus with two minutely granulate carinae. Male first pleopod sinuous; apical process filiform, arcuate, bent distad.

Colour

“[G]rigio-plumbeo di sopra, grigio-violaceo chiaro nelle parti inferiori e nelle zampe posteriori. Estremità delle dita della mano, tarsi anco più chiari.” (Targione-Tozzetti 1877: 198). “Surface of carapace dark olive gray to dark grayish olive, ventral surface vinaceous buff to avellaneous.Punctiform depressions on carapace gray or colourless.” ( Shen 1932: 25).
