FIGURE 2 in Eudontomyzon graecus, a new nonparasitic lamprey species from Greece (Petromyzontiformes: Petromyzontidae)
FIGURE 2. Oral disc of Eudontomyzon graecus, sp. n. A: holotype (immature male; CMNFI 1986–0741; disc length, 6.5 mm; TL, 136.5 mm); B: a paratype (immature female; CMNFI 1986–0720; disc length, 7.5 mm; TL, 141 mm). The photo of the paratype is from fig. 12e in Renaud (1982).
FIGURE 3 in Eudontomyzon graecus, a new nonparasitic lamprey species from Greece (Petromyzontiformes: Petromyzontidae)
FIGURE 3. Tail length residuals of 26 adults of Eudontomyzon graecus sp. n. (․) and 40 adults of E. hellenicus (˔) against their total length. The open symbols represent the respective holotypes. The horizontal line in the graph is the line of maximum separation (88%). Two pairs of E. graecus individuals lying above this line had identical coordinates; therefore, only 24 of 26 symbols are visible for this species.

FIGURE 1. Lateral view of the holotype (immature male; CMNFI 1986–0741; TL, 136.5 mm) of Eudontomyzon graecus, sp. n.
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.

FIGURE 1 in Lampetra soljani, a new brook lamprey from the southern Adriatic Sea basin (Petromyzontiformes: Petromyzontidae)
FIGURE 1. Maximum likelihood estimation of the phylogenetic relationships based on the mitochondrial COI barcode region (Tamura 3-parameter model, discrete Gamma distribution for rate differences with 5 categories +G parameter = 0.3409). Nucleotide positions with less than 100% site coverage were eliminated resulting in 652 analysed positions. Numbers of major nodes indicate bootstrap values from 1000 pseudoreplicates from the ML, NJ and MP method. The tree is drawn to scale (except to outgroup), with branch lengths measured in number of substitutions per site.

FIGURE 1. Map of localities discussed in text. Type localities are indicated by species labels, and numbers correspond with identifiers in Table 1. Stars are localities for populations of L. pacifica; dots are localities for populations of L. richardsoni. The Tualatin River (4) includes three sampling sites, including McKay Creek.
