Type locality. Off coast of Pernambuco, 8°25.5’S, 34°48.5’W, 33 m, Brazil.

Distribution. Bermuda; southeast Florida and Bahamas; Antilles; western Caribe, from Yucatán Peninsula to Colombia; Brazil (Fernando de Noronha, Amapá, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia and Espirito Santo, Trindade Island and Vitória-Trindade Seamount Chain, present study); 1– 100 m.

Remarks. Among the “provenzanoi group” of species from the western Atlantic, Pagurus provenzanoi share the presence of multispinose ocular acicles with P. brevidactylus , P. carolinensis , P. leptonyx , P. trichocerus . However, P. provenzanoi can be separated from P. leptonyx and P. trichocerus by the presence of short setae on antennal flagellum, whilst the latter species have long setae on the antennal flagellum. Pagurus provenzanoi is morphologically closely related to P. brevidactylus and it is not uncommon that the two species are confused with each other. Lemaitre & Tavares (2015), for instance, reported one ovigerous female of P. brevidactylus [MZUSP 36506, not MZUSP 16832 as reported by Lemaitre & Tavares (2015)] from the Vitória-Trindade Seamounts Chain. However, reexamination herein of that specimen revealed that it actually belongs to P. provenzanoi . The two species can be best differentiated by the presence of dense, short mat-like setae on the dorsal surface of the cheliped propodi in P. provenzanoi , vs. dorsal surface of propodi with scattered, long stiff setae in P. brevidactylus .

Pagurus provenzanoi is herein recorded for the first time from the Vitória-Trindade Seamount Chain (Jaseur, Davis and Dogaressa seamounts and from Trindade Island ( Fig. 1 A–C).

Nucci & Melo (2007) have recorded P. provenzanoi from as south as Santa Catarina (~ 27°S) based on a male from Porto Belo (MZUSP 13808). Reexamination of that specimen revealed that it actually belongs to P. brevidactylus (Lima & Santana, unpublished).
