Abstract

A new genus, Motobdella, is recognized for Erpobdella montezuma Davies, Singhal, and Blinn, 1985. In addition, a new species for this genus, Motobdella sedonensis, is described. Morphological characters that include the presence of crop caeca, number and size of the eyes, arrangement of the eyes, arrangement of ovisacs, position of the gonopore, structure and size of the sensilla, coloration, and position of the anus distinguish this new genus from Erpobdella and Nephelopsis. DNA fingerprinting methods were used to examine the phylogenetic relationships of these genera and corroborated the morphological data supporting the evolution of this genus with two distinct species.
