Environnement : Marine & Land - Substrat/Association : Soft bottom (mud or sand)

Vertical range : Intertidal - Min-Max observed: 0-1 m

Lesser Antilles data
Distribution: ICA (?Guadeloupe, Trinidad), IOV (?Bonaire, Curaçao). Intertidal. WA (continental?).
Uca speciosa - Rathbun, 1924: 19, Curaçao [coll. C.J. van der Horst, 1920]. - Hagen, 1970: 227, Curaçao [Caribbean Uca groups; from litterature] - Probably not Uca (Leptuca) speciosa (Ives, 1891) but Leptuca cumulanta (Crane, 1943) instead; see comment.
Uca spinicarpa Rathbun - Rathbun, 1936: 388, Bonaire [coll. P. Hummelinck, 1930]. - Chace & Holthuis, 1948: 27, Bonaire [Coll. P.Hummelinck] - Probably not Leptuca spinicarpus (Rathbun, 1900) with geographic range probably limited to the Gulf of Mexico (cf. Felder et al., 2009; Bezerra & Coehlo, 2010). Possibly L. cumulanta instead.
Uca cumulanta - Chace & Hobbs, 1969: 211, Curaçao. - Hagen, 1970: 226, Trinidad, Curaçao [Caribbean Uca groups; from littérature; with mention that it is missing in Lesser Antilles Islands]. - Vaslet et al., 2013: 245, annexe 3, Guadeloupe [from Bourgeois-Lebel 1982, not seen, see comment].
Uca (Leptuca) cumulanta - Crane, 1975: 242, 608, Trinidad, Curacao [apparently absent from any other islands in the Caribbean].
Comment: About Uca speciosa (Ives, 1891) Crane (1975: 238) indicates - The specimens previously recorded from the island of Curacao are all representatives of the allopatric species, cumulanta, as is the single record from Jamaica. The subgenus Leptuca is elevated to genus in Shih et al. (2016, Raffles Bulletin: 153, new genus). Hagen (1970) and Crane (1975) indicate that L. cumulanta, present in Curaçao and Trinidad, is 'apparently absent from any other islands in the Caribbean'. The single record in Guadeloupe, not verified herein, appears therefore doubtful and needs to be confirmed.

Comment(s) on data
Chace & Hobbs (1969: 216) - For Uca speciosa (Yves, 1891) - The male from Kingston Harbor, Jamaica, reported as Uca spinicarpa by Rathbun (1918) proves to be U. speciosa, whereas the two lots from Curacao recorded as U. speciosa by the same author (1918 and 1924) are U. cumulanta.
