Fig. 4 in Cryptic multicolored lizards in the Polychrus marmoratus Group (Squamata: Sauria: Polychrotidae) and the status of Leiolepis auduboni Hallowell

Fig. 4. Localities of members of the Polychrus marmoratus Group. Green pushpins denote localities from which DNA was sampled. Red stars denote locations for Polychrus auduboni, black stars denote locations for P. marmoratus. Black circular markers represent unconfirmed locations for members of the P. marmoratus group based upon the literature and specimens reported in VertNet. The blue star is the type locality for P. marmoratus (Linnaeus). The purple star is the type locality of P. auduboni Hallowell. The green star is the type locality for Polychrus virescens Schniz, the orange star is the type locality for P. neovidanus Wagler.

Fig. 3. Consensus maximum likelihood tree for combined 16S in Cryptic multicolored lizards in the Polychrus marmoratus Group (Squamata: Sauria: Polychrotidae) and the status of Leiolepis auduboni Hallowell

Fig. 3. Consensus maximum likelihood tree for combined 16S and COI sequence data from seventeen Polychrus tissue samples (1,035 bp total). Bootstrap support values are indicated at each node, if greater than 50%. Samples are indicated by their museum accession number and country of origin, if known. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. For details of analysis, see text.
