FIGURE 4. A in Eudontomyzon graecus, a new nonparasitic lamprey species from Greece (Petromyzontiformes: Petromyzontidae)

FIGURE 4. A: Trunk length residuals of 18 ammocoetes of Eudontomyzon graecus sp. n. (․) and 219 ammocoetes of E. hellenicus (˔) against their total length. The horizontal line in the graph is the line of maximum separation (97%). One pair of E. graecus lying below this line had identical coordinates; therefore, only 25 of 26 symbols are visible for this species. Twenty pairs and two sets of three E. hellenicus individuals lying above this line had identical coordinates; therefore, only 195 symbols are visible for this species. B: Tail length residuals of 18 ammocoetes of Eudontomyzon graecus sp. n. (․) and 219 ammocoetes of E. hellenicus (˔) against their total length. The horizontal line in the graph is the line of maximum separation (97%). One E. graecus and one E. hellenicus individual lying above this line had identical coordinates and the symbol for E. graecus is the one that appears; therefore, all 18 individuals of E. graecus are visible on the graph. Twenty-four pairs and four sets of three E. hellenicus individuals lying below this line had identical coordinates; therefore, taking into account the individual with identical coordinates to the E. graecus mentioned above, only 186 symbols are visible for E. hellenicus.
