Mayotte data
Thalamita prymna (Herbst, 1803)
Material examined — Mayotte KUW 2009, st. 7, trap, cardinal Buoy Kongo, 32 m, 1 F 37.2 x 52.8 mm, MNHN B32474, MNHN-IU-2009-1236; st. 38, Bay Chiconi/Sada, southwest, coll. J. -M. Bouchard, V. Dinhut, 24/07/08, 1 M 37 x 62 mm, MNHN B32475, MNHN-IU-2009-1237.
Other records — Thalamita prymnoa Herbst - Hoffmann, 1874: 39, Mayotte (indicated in list but not p. 9 under the species). - Thalamita prymna - Milne-Edwards, 1873: 164 Le Muséum d'histoire naturelle en possède de nombreux représentants provenant de Mayotte. - Crosnier, 1962 : 136, synonymy with Hoffman reference.
Remarks — Large specimens examined are identified to T. prymna by using keys in Crosnier (1962), Stephenson (1972) and Appel & Spiridonov (1988) with however a few variations that are attributed to their size: pubescens on carapace almost absent; ridge of carapace between 2nd anterolateral teeth, limited to mesogastric region; outer face of palm with inferior costa only visible, median and upper costae being reduced to granules.
Geographic and depth ranges — IWP, Red Sea, South Africa to Japan, French Polynesia; intertidal to 32 m (this work).
