The taxonomic status of Eurycea bislineata, the two-lined salamander, in Ohio is equivocal. Recently, Guttman (1989)suggested that an investigation of reproductive isolating mechanisms
might aid in clarifying the status of two possible cryptic species in eastern Ohio.
Two sets of experiments were performed using members of two populations of salamanders considered to represent Guttman's cryptic species. Intrapopulational and interpopulational sexual encounters were arranged resulting in the conclusion that the populations are conspecific. Results of male olfactory discriminatory tests reinforced the single species concept.
