DESCRIPTION

Dorsal surface of carapace bearing closely-spaced perliform granules on branchial, cardial and intestinal regions, along branchio-cardiac grooves, and medially on gastric region. Branchio-cardiac grooves shallow. Lateral frontal lobes rounded, minutely granulate. Anterior margin of epistome medially notched, subhepatic margin prominently crenulate; subhepatic facet granulate.Tumescent outer orbital angle followed by perliform granules and obsoletely granulate protuberance.Anterolateral granules on margin of carapace larger than granules on posterolateral and posterior margins. Epimeral surface smooth; epimeral margin minutely beaded,granules increasing in size on posterior margin. Endognath of external maxillipeds indistinctly punctate laterally,exognath reniform, punctate.Pterygostomian region prominently granulate.Fourth thoracic sternite in male with a granulate region anterolaterally,anterior margins of thoracic sternites granulate;anterior margin of abdominal sulcus granulate.Fused male abdominal segments 3-6 basally granulate. First and second abdominal segments in female laterally granulate, fused abdominal segments granulate basio-laterally. Cheliped merus 1.3 as long as carapace in male, 0.8as long in female; its dorsal surface with parallel rows of perliform granules, decreasing in size distally;anterior and posterior surfaces with rows of perliform granules, diminishing in size posteriorly. Carpus with row of minute granules on inner margin; patch of minute granules distally on upper margin. Upper and lower surfaces of propodus minutely granulate, granulation extending to fingers; inner margins of dactyl, pollex serrulate, serrulation more prominent distally. Pereiopodal meri bear single minutely granulate line ventrally; propodi dorsally and ventrally carinate.Male first pleopod with apical process filiform, needle-like, nearly as long as shaft.

Colour

“The upper surface of the carapace and the anterior legs are of a more or less dark cinerous gray, the hands being marbled with a lighter rose-colour; the under surface of the carapace, like the ambulatory legs, except the white tarsi, are of a pale rose colour. The granules are all white.” (de Man 1881: 128). “The body is dull brown to grey with greenish mottling on the lateral areas; ovig. females were mottled green all over […] The appendages were banded with green.” ( Tirmizi & Kazmi 1988: 108).

REMARKS

Leach (1817: 22) recognized that Cancer cancellus Herbst, 1783 , is identical with Leucosia scabriuscula Fabricius, 1798 .
