Third maxillipeds completely closing buccal cavity. Ischium long, with marked longitudinal internal groove. Merus: external margin regularly curved, oblique, without marked angle, with distal part markedly narrow and produced; internal margin with prominent lobe in half proximal portion. Carpus inserted in notch of antero-internal margin of merus; propodus thick; dactylus about as long as merus; inner margins of propodus and dactylus with brush-like setae. Exopod longer than endopod ischium. Mxp3 coxa with only proximal portion visible, its lateral projection hidden by junction of thoracic sternum (sternite 4) with pterygostome.

Carpus with setae on superior margin and inner surface; merus long, triangular in cross section, anterior border straight, with blunt teeth, smaller distally. Propodus of both chelae with two conspicuous, deep depressions at outer surface of palm near base of dactylus (absent in females), both as two dark spots, even well visible in specimens photographed

. Inner surface of both chelae dished on half posterior part; thick patches of dense setae largely extending on half anterior part of propodus and partially extending along occluding margins. Dark colour extending on about three-quarters of fixed finger and practically on whole part of dactylus of both crusher and cutter. Crusher: palm convex, inflated, smooth, except for two depressions located near base of dactylus: one horizontally directed and the largest; the other obliquely directed, smaller. Fingers thick, slightly gaping at occluding margins; two weak, blunt teeth, proximal and median, on occluding margin of dactylus; a blunt but marked subproximal tooth and smaller ones on occluding margin of fixed finger. Cutter: palm elongate, with subparallel borders, smooth, except for two depressions near base of dactylus, similar to those of the crusher; both fingers not gaping at the occluding margins; dactylus elongate, hollowed, with occluding margin smooth; fixed finger very thick, dished on inner surface; occluding margin nearly straight, with 2-3 small teeth, size progressively diminishing forwards. P2-P5 shorter than chelipeds; P3 and P4 longest; meri with patch of dense setae on ventral margins, carpi, propodi fringed on dorsal and ventral margins with felt of short, stiff setae, mixed with sparse longer setae, the patch being dense, thicker on inferior margin. Dactyli rather stout, with patches of short setae.

The function of the pigmented pits or spots present on the palm of chelipeds (also on the subocular regions in others species) of certain bythograeids is supposed to be sensory.

This reversion of chelipeds, which causes a dramatic rearrangement and triggers a new allometric growth, is thought to have induced a novel implantation of the spots on the chelae, mainly when autotomy or loss occurs at a large size of crabs. These atypical individuals, without other equivocal morphological evidence and presumably not genetically cryptic, are here treated as
