Crustáceos (Decapoda: Brachyura) fósiles de Cuba.

Abstract

Three families, two genera and two species are recorded for the first time for the Cuban Cretaceous to Pleistocene geologic age. The genera Persephona Leach, 1817 (Leucosiidae), Mithrax Desmarest, 1823 (Majidae) and Panopeus Milne Edwards, 1834 (Panopeidae) are well known in the Recent of the Caribbean region. Fossils of these taxa are found in formations from lower Miocene to upper Pleistocene in age in the Caribbean. Portunus oblongus Rathbun, 1920, an extinct species, is the first species of Portunus Weber, 1795 recorded from Cuban Oligocene–Miocene. Lophoranina precocious Feldmann, Vega, Tucker, García-Barrera y Avendaño, 1996 (Raninidae), other extinct species, is also recorded for the Cretaceous (Campanian- Maastrichtian). This is the most ancient species of decapod crustacean found in Cuba.
