Terrestrial Amphipod Crustaceans from Trinidad

E.L. Bousfield

Abstract


This report concerns a group of shore-dwelling amphipod crustaceans, commonly called beach fleas or sand hoppers, of world-wide tropical and warm-temperate distribution. These animals were probably among the first marine creatures attempting to colonize the land and are among the most primitive of existing terrestrial arthropods. As previous knowledge of the talitrid fauna of the Caribbean region is very imperfect, and that of Trinidad nil, the present records are noteworthy. Orchestia platensis Kr. (eastern Canada to Argentina) and Talorchestia sulensoni Stebb. (originally described from Madeira) are herewith recorded for the first time from Trinidad, and the latter for the first time from America.
