Summary: | A new species of crayfish, Orconectes (Procericambarus) raymondi, is described from unglaciated portions of south-central Ohio, North America. Of the recognized members of the subgenus, it is morphologically most similar to Orconectes (P.) putnami, found in Kentucky and Tennessee and is easily separated from it by the presence of a strong rostral carina. It is distinguished from other recognized members of the subgenus by the rostral carina, mandible structure, and a first form male gonopod having a central projection approximately 50% of total gonopod length. An amended version of Taylor's key to the members of the Orconectes juvenilis complex is provided. |
