World Distribution
(Anker, 2017, Zootaxa) - Distribution. Western Atlantic: confirmed only from Puerto Rico (Vieques Island, type locality); U.S. Virgin Islands (Peter Island); Florida (Fort Pierce); and Brazil: Bahia (Abrolhos Archipelago) (Rathbun 1901; Schmitt 1924a, 1935; Chace 1972; Soledade et al. 2015; present study). Records from Bermuda (Sterrer 1986); southern Gulf of Mexico (Felder et al. 2009); Curaçao (Schmitt 1924a); Colombia (Santa Marta, Campos 1995); Panama (San Blas Islands, Williams et al. 2001); Cuba (Gulf of Batabano, Martínez-Iglesias 1986; Martínez-Iglesias et al. 1996) will require confirmation as at least some of them may refer to the closely related A. paratrigona sp. nov., which occurs from Bermuda to the southern Caribbean Sea (see below). For the same reason, the identity of shrimps identified as A. trigona on colour photographs in Sterrer (1986) and Humann et al. (2003) also remains uncertain. - intertidal to at least 30 m

Lesser Antilles data

Alpheopsis trigonus - Chace, 1972: 56, (partim; VGI Peter Island; but not Barbuda = A. paratrigona Anker, 2017, Zootaxa).
