Popis:	Allozyme variation in Neoechinorhynchus was used to examine the hypothesis that the occurrence of a single morphologically variable species may account for the observation of overlapping distributional patterns within the intestine of the yellow-bellied slider turtle (Trachemys scripta). Genetic analysis of 6 enzyme loci excluded the single species hypothesis and was consistent with the occurrence of 4 congeneic species within the turtle population. Discriminant analysis of multilocus genotypes, however, indicated that species designation based primarily on female body and egg morphology may not be error free
