Lamy by traps 300 m, no station data, MNHN-IU-2013-4422. - Poupin & Corbari, 2016: in press, Guadeloupe (first record), Karubenthos II 2015, st. DW4555, 15 June 2015, 16°23.53'N, 60°49.67'W, 258-100 m, MNHN-IU-2013-18935; st. DW4613, 25 June 2015, 16°24.16'N, 60°50.1'W, 210-240 m, MNHN-IU-2013-19077.
Comment: this specimen is broken but easily identifiable by the horseshoe sculpture on the dorsal surface of its carapace. The species was already recognized around Guadeloupe during Karubenthos 2012 (coll. D. Lamy with trap, depth unoticed).

Comment(s) on data
Comment for T. simplex: This species is perhaps a juvenile of T. granulosus, with variation of spines. Rathbun (1925: 343) notes that 'It is extremely likely that the simplex form (of which 3 males are known) is the male of the granulosus, of which only a female is known and was taken in the same haul as the type male of simplex'. Chace (1940: 65) also considers that the two species are probably identical "Thus, although all four of these specimens differ somewhat in the form of the cardiac region and its accompanying trench, there is every likelihood, as Miss Rathbun has suggested, that the two described species of the genus are identical". This synonymy is confirmed by Santana & Tavares (2010: 147).
