Description
Summary:Bromeliads can hold water in their axils, which can harbor an astonishing diversity of macro invertebrates, including decapod crustaceans. Except of a casual report from Trinidad, true freshwater crabs in these phytotelmata have been found exclusively in the Old World, and observations in the New World of crabs associated with bromeliads have been limited to sesarmid crabs, non-primary freshwater crabs that generally do not breed in freshwater. Here we report the presence of a true, or primary, freshwater crab in water-filled axils of a bromeliad in the Neotropics. Immature specimens of the pseudothelphusid crab provisionally identified as Epilobocera cf. gilmanii (Smith, 1870) were collected from inside the bromeliad Hohenbergia penduliflora (A. Richard) Mez. in western Cuba. Pseudothelphusid crabs have developed additional respiratory structures, which make them suitable candidates for a life in phytotelmic microhabitats. It is still uncertain whether in Cuba these crabs actually breed in phytotelmata or only use this microhabitat during their early life stages.
