Galathea serricornis Loven, 1852: 22.
Munidopsis serricornis.— Baba, 2005: 185, 295 (synonymy and list of occurrences).— Macpherson & Segonzac, 2005: 42.
Material examined. Madagascar (A. Crosnier collection), Stn CH 108, 735– 760 m: 1 M 8.7 mm, 1 ovig. F 7.0 mm (MNHN-Ga1426).
Remarks. The present specimens agree quite well with the northeastern Atlantic material. As Mayo (1974) pointed out, the epigastric spines are absent in M. serricornis (marked striae in some cases), being a good character to separate this species from other species with tridentate rostrum.
Distribution. The geographical distribution of this species may be reviewed, and some of the previously reported material could belong to recently described species (e.g., M. treis Ahyong & Poore, 2004 or M. ternaria n. sp.). The species is known from the Eastern Atlantic from Norway and Iceland to Cape Vert, between 96 and 2091 m (d’Udekem d’Acoz 1999, Macpherson & Segonzac 2005). Benedict (1902), Chace (1942), Pequegnat & Pequegnat (1970) and Mayo (1974) reported the species from the southeastern United States to Gulf of Mexico (458–1446 m). The present material was collected in the southwestern Indian Ocean, at 735– 760 m.
