| Abstract | Material, mostly deep-water, belonging to eight families of brachyuran crabs are listed from the MAINBAZA, MIRIKI, and ATIMO VATAE expeditions to the Mozambique Channel and northwestern and southern Madagascar. A new species of Ethusa Roux, 1830 (Ethusidae), unique for its vivid colouration and collection in shallow water 13-22 m deep, is described from southern Madagascar. Sphenomerides trapezoides (Wood-Mason & Alcock, 1891) (Trapeziidae) is for the first time recorded from a host, a sponge, and the presence of mucus-gathering setae are for the first time demonstrated in this rarely collected species. A neotype for Dorippe sexdentata Stimpson, 1858 (Ethusidae) is designated to stabilise the taxonomy of the species. The male and the vulva of Ethusa machaera Castro, 2005, and the vulva of E. sexdentata (Stimpson, 1858) are described for the first time. Five species are new records for Madagascar: Crossotonotus spinipes (De Man, 1888) (Crossotonotidae); Carcinoplax ischurodous (Stebbing, 1923), Goneplax clevai Guinot & Castro, 2007, and Ommatocarcinus pulcher Barnard, 1950 (Goneplacidae); and Pseudopalicus sexlobatus (Kensley, 1969) (Palicidae); while Ethusina somalica (Doflein, 1904) (Ethusidae) is a new record for the southwestern Indian Ocean. |
