AbstractRecently discovered crabs from the Middle to Upper Eocene of northern Bonaire, Netherlands Antilles, include well-preserved carapaces of Montezumella rutteni Van Straelen, originally described from an incomplete holotype. The more comprehensive description of this species provided herein includes documentation of the first attributable left cheliped of Montezumella. From the same locality, Ocalina sublevis sp. nov. considerably extends the known geographic range of this genus. Both of these Tethyan decapod genera apparently migrated west from the Mediterranean region during the Eocene. Despite these new determinations, decapod crustaceans remain poorly known from the Eocene of the Antillean islands. Additionally, Callianassa pustulosa Withers from the Eocene basal complex of Barbados is tentatively reassigned to Callichirus.
