Abstract

Abstract Procambarus montebelloensis, new species, is described from Montebello lake district in Chiapas, Mexico. The new species can be distinguished from P. mirandai by a gonopod with shorter and more slender mesial process apically directed, a less pronounced cephalic shoulder and a shorter central projection. Regarding the external morphology, in the new species the anterior portion of the head is notably directed downwards, and it has a more elongated chela with a distinct dentition.
