Abstract: Thirteen morphometric characters were compared between two cryptic species of gray treefrogs from Ohio. Discriminant function analysis using snout-vent length, shank length, and thigh length correctly classified 76.7% of diploid Hyla chrysoscelis and tetraploid//. versicolor. Ohio diploids are more similar in size to those in Texas than to those of Michigan and Wisconsin or southeastern states. Tetraploid treefrogs in Ohio are intermediate in size to those of Texas, North Carolina, and Wisconsin. Latitudinal and longitudinal clinal variation in snout-vent length is apparent in both species.
