Nestor H. Campos and Rafael Lemaitre
Abstract.—A. new sf)ecies of a diogenid hermit crab, Calcinus urabaensis, is described from the Gulf of Uraba, on the Caribbean coast of Colombia. The new species is the third in the genus described from the western Atlantic, and can be distinguished from the other two known species of the genus Calcinus in the region, C. tibicen (Herbst) and C. verrilli (Rathbun), by differences in coloration and armature of the dactyl of the left cheliped, third pereopod, and telson. A comparison of the three species is included. /?e5Mm^«.—Se describe una nueva especie de cangrejo ermitano pertenecienta a la familia Diogenidae, Calcinus urabaensis, colectada en el Golfo de Uraba, Caribe sur. La nueva especie es la tercera conocida de este genero en el Atlantico occidental, y se diferencia de las otras dos especies del genero Calcinus de la region, C. tibicen (Herbst) y C. verrilli (Rathbun), en la coloracion y espinas del dactilo de la quela izquierda, tercer pwreopodo, y telson. Se presenta una comparacion de las tres especies.
