Mayotte data
Catoptrus rathbunae Serène, 1966
Material examined — Mayotte KUW 2009, st. 27, Islet Mbouzi, 'patate Sud-Est', 4-20 m, 2 FF 4.3 x 5.8 and 5.3 x 7.3 mm (photo ' 5.3x7.7'), MNHN B32521, MNHN-IU-2009-1281; st. 28, east Islet Mbouini, 3-20 m, 1 M 5.6 x 8 mm, photo, MNHN B32522, MNHN-IU-2009-1282; st. 30, Rani reef, double barrier, 3-15 m, 1 M 4.9 x 6.9 mm, MNHN B32523, MNHN-IU-2009-1283; st. 35, Surprise reef, Longoni pass, 4-25 m, 1 M broken, approximately 5.2 x 7.3 mm, MNHN B32524, MNHN-IU-2009-1284.
Remarks — Just after the fieldwork these specimens had been attributed erroneously to Catoptrus nitidus, also present in Mayotte. However, careful re-examination, especially of male pleopod, have proved that they are instead Catroptrus rathbunae. Vannini & Innocenti (2000 : 257, fig. 8-9) can be consulted for diagnosis and illustration of male pleopods in C. nitidus/rathbunae.
