Abstract

A new species of Graptocarcinus, G. collinsi Vega, is recorded from lower Maastrichtian (Upper Cretaceous) strata assigned to the Arroyo Grande Formation to the south of Rodas (central Cuba). The three specimens available form part of a diverse decapod crustacean fauna currently under study. The new species differs from its Early and Late Cretaceous congener from Mexico, the United States, England, Spain, France, the Czech Republic and the Netherlands in being much wider than long, having a larger mean carapace size, in lacking or having an extremely weak cervical groove and coarse and densely arranged granules on the dorsal carapace.
