Lesser Antilles data

Clibanarius vittatus - Hazlett, 1966: 45, Curaçao. - Lira, 1997, tab. 3, Margarita. - Hernández et al, 1999: tab. 1, Margarita [Laguna de Las Marites] - Probably not Clibanarius vittatus (Bosc, 1802), distributed in southeastern coast of the United States and Gulf of Mexico but C. symmetricus instead (cf. Negri et al., 2014; Lemaitre & Tavares, 2015).
Clibanarius symmetricus - Negri et al., 2014: 848, Tobago, Trinidad, Margarita.
Comment: this hermit crab, affiliated and for a long counfounded with Clibanarius vittatus (Bosc, 1802) was resurrected by Negri et al. (2014).

Hazlett (1966: 45) for 'C. vittatus' from Curaçao: This species is morphologically and behaviorally very similar to Clibanarius cubensis. It is a medium-large, slowly moving crab, averaging only slightly less in size than C. cubensis. The species is very rare on Curaçao.

French Guiana and surroundings areas: Guiana, Suriname, Brazil (Amapà)
Pagurus symmetricus Randall, 1840: 133, type locality, Suriname [restricted by lectotype selection in Negri et al., 2014: 851].
Clibanarius cayennensis Miers, 1878: 657, Cayenne, French Guiana. Accepted as C. symmetricus (Randall) in Negri et al. (2014: 851).
Clibarnarius vittatus (Bosc) – Holthuis, 1959a: 141, Guyana, Suriname [Guyana from Graham, 1955, Seashore life of British Guiana: 35; not consulted]. – Not C. vittatus (Bosc) but C. symmetricus (Randall) in Negri et al. (2014).
Clibanarius symmetricus – Negri et al., 2014: 851, Suriname, French Guiana [holotype of Clibanarius cayennensis Miers, 1 male (dry) sl 10.2 mm, Cayenne, French Guyana (NHM 1879.21.1); French Guyana: 3 males (sl 5.5-7.1 mm), Cayenne, Rémiré Beach, 04°53'S, 52°15'W, 25 September 2000, collector not informed, MZUSP 16171; Suriname, coll. Dr. Herring (ANSP 3229)].
Distribution/Habitat – WA; Marine; 0–22 m (mostly intertidal).
Remark – The record of Clibarnarius vittatus from Brazil Amapá in Nucci & Melo (2015: 334; not citing Negri et al., 2014) must be of that species, by implication.

Comment(s) on data
Sibling species of C. vittatus (Bosc, 1802) and for a long time counfounded with it. C. vittatus is now known with certainty from southeastern coast of the United States and Gulf of Mexico only. The carpi in C. symmetricus each have three straight, whitish longitudinal stripes, whereas the carpi in C. vittatus sensu stricto each have four stripes.

(Negri et al. 2014: 849) - Three names have so far been considered synonyms of Bosc’s (1802) C. vittatus, a species described based on specimens from the Carolinas (“côtes de la Caroline”) on the southeastern coast of the United States: Pagurus symmetricus, Randall, 1840 (transferred by Dana (1852) to Clibanarius), C. speciosus Miers, 1877, and C. cayennensis Miers, 1877 (Holthuis, 1959; Forest and de Saint Laurent, 1968; McLaughlin et al., 2010). Here we argue, based on molecular and morphological (coloration) evidence and using phylogenetic methods, that Bosc’ name should apply to northern populations of C. vittatus sensu lato from at least the southeastern coast of the United States and Gulf of Mexico, whereas Randall’s name, C. symmetricus, should be resurrected and applied to southern populations of C. vittatus sensu lato ranging from at least Belize in the southwestern Caribbean to Brazil.
