présentent des péréiopodes clairs avec de larges bandes colorées transversales de teinte rougeâtre. On observe souvent une large bande, plus ou moins médiane, sur le mérus et le propode, et une autre étroite, sub-basale sur le carpe. Les dactyles sont souvent décolorés. Mais ce schéma semble très variable: les bandes varient beaucoup en largeur et en position, les dactyles peuvent être entièrement colorés. Les extrémités des doigts des chélipèdes sont le plus souvent colorées. La carapace présente également de grandes variations et ce chez des exemplaires de la même espèce capturés simultanément. Sa teinte générale est marbrée, le rouge et le blanc (ou plutôt le jaunâtre) étant disposés de manières très diverses. Souvent les zones méso- et métagastrique sont fortement décolorées, tandis que la pointe des dents antérolatérales est rouge; chez les espèces fortement granuleuses, les gros granules sont fréquemment colorés en rouge. La question devra être reprise par des examens de matériel frais et apportera, certainement, des éléments intéressants.
