Abstract

A dichotomous key to the species of Neoechinorhynchus (Acanthocephala: Neoechinorhynchidae) occurring in turtles is presented based on characters of the posterior extremity of fully gravid females and the egg. The 9 recognized species of Neoechinorhynchus in turtles can be identified reliably based on these characters alone. Identification requires fully gravid females that have been properly killed and fixed. Immature females and males cannot be identified using the key presented herein.
