I have separated C. snelli Curran, 1927 from C. leucopogon (Wiedemann, 1824). C. snelli is distributed from coasts of Tanzania and Kenya across Madagascar, Reunion, Mauritius, Aldabra, Rodriguez and Seychelles to western Indian coast (Goa), Chagos Archipelago and Maldives. C. leucopogon is spread in eastern Indian Ocean and western Pacific.
