Calappa angusta A. Milne Edwards 1880a:18, ?Lesser Antilles [part, in Williams & Child, 1989, not Cyclozodion angustum A.Milne-Edwards; locality of 'selected juveniles' not indicated in Williams & Child, ?Lesser Antilles]. - Cyclozodion tuberatum Williams & Child, 1989: 110 [description and synonymy, no places in Lesser Antilles].
Cyclozodion tuberatum - Guadeloupe (first record for Lesser Antilles), Karubenthos 2012, st. GD27, 15 May 2012, 16°25'N, 61°33'W, 120 m, MNHN-IU-2013-4449 (JL844, Photo, re-det Felder/Poupin April 2014, from C. ?ocellata, 1 sp. Badly preserved, 10.6x11.5 mm); st. GD28, 15 May 2012, 16°25'N, 61°33'W, 110 m, MNHN-IU-2013-4519 (Photo-JL843, first as Calappa galloides, re-det. Felder April 2014, based on photo; checked by Poupin on specimen, 1 F 11.1x11.8 mm, but telson of this female is much more elongated that fig. 4h in Williams & Child).
Cyclozodion tuberatum - Guadeloupe, Karubenthos II 2015, field det. J. Poupin, st. DW4553, 15 June 2015, 16°20.82'N, 60°53.3'W, 162-111 m, MNHN-IU-2013-18914.
Comment: present determination is based on key in Williams & Child (1989) and previous identification of this species in Guadeloupe during Karubenthos 2012, at similar depths (110-120 m). It seems that the tubercles on the carapace are less developped on the Juveniles of Cyclozodion tuberatum and that they can be confused with Cyclozodion angustum (see under that species). Calappa tortugae Rathbun, 1933 is also very similar and can be separated by confidence only with examination of the male pleopod.
