FIGURE 6 in A new species of Alopoglossus lizard (Squamata, Alopoglossidae) from the Southern Guiana Shield, northeastern Amazonia, with remarks on diagnostic characters to the genus
FIGURE 6. Vectorized drawings created based on figures from Ávila-Pires (1995) and Kohler et al. (2012), and on a specimen photograph from Torres-Carvajal & Lobos (2014), showing the use of different names in literature for a same scale character. (A) Alopoglossus viridiceps: enlarged scales (Torres-Carvajal & Lobos 2014: 114); (B) Loxopholis snethlageae: fourth pair of chinshields (Ávila-Pires 1995: 412); (C) Alopoglossus buckleyi: pregulars (Ávila-Pires 1995: 321); (D) Loxopholis percarinatum: fourth pair of chin shields (Ávila-Pires 1995: 404); (E) Alopoglossus copii: tiny scales (Kohler et al. 2012: 183). For a standardization of the nomenclature of scale characters, as suggested here: red, fourth pair of chin shields; blue, pregular scales.

FIGURE 3 in Phylogeography of the endangered sand dune whiptail lizard Glaucomastix abaetensis (Dias, Rocha & Vrcibradic, 2002) with the description of a new species
FIGURE 3. Mismatch distribution, Fu's Fs, and Tajima's D neutrality tests, and the sums of squared deviations (SSD) for each major lineage. The expected frequency for mismatch distribution is based on a population growth-decline model determined using DnaSP 5.10.01 (Librado & Rozas 2009). The x axis shows the number of pairwise differences, the y axis shows the frequency of the pairwise comparisons. The observed frequency is represented by a continuous black line, whereas the dashed gray lines represent the expected frequency.
FIGURE 2. a in Phylogeography of the endangered sand dune whiptail lizard Glaucomastix abaetensis (Dias, Rocha & Vrcibradic, 2002) with the description of a new species
FIGURE 2. a) Bayesian phylogenetic tree inferred from combined mtDNA and nDNA (50% majority-rule consensus) for Glaucomastix abaetensis, and Bayesian species delimitation results assuming a fully resolved, three-species guide tree (bold red lines). The marginal probabilities for speciation are displayed at each node for each combination of priors for θ and τ: LD, θ = G (1, 10) and τ0 = G (1, 10); SS, θ = G (2, 2000) and τ0 = G (2, 2000); LS, θ = G (1, 10) and τ0 = G (2, 2000). Results from both rjMCMC algorithm 0 and 1 are displayed. There was high speciation probability (> 0.95) for southern and northern clades node under all combinations of priors and rjMCMC algorithm, providing robust support for recognition of two species. b) Phylogenetic reconstruction for Glaucomastix including southern lineage (G. abaetensis; MZUSP 104240) and northern lineage (G. itabaianensis sp. nov. holotype; MZUSP 104255) as a new species under BSD approach (bold red line). Colored dots represents samples for different localities as shown in the legend (lower-left corner). Colored squares on nodes correspond to Bayesian posterior probabilities values according to color gradient (see the legend; values <70% were suppressed). The best-fit model of evolution seletected for our data was GTR + G for 16S, cyt b and ND4, F81 for BDNF, and HKY+G for NT3. Kentropyx altamazonica was used as outgroup.

FIGURE 1. a) map of northeast Brazil showing the localities used in molecular (colored dots) and morphological analysis (colored dots and black diamonds). Light blue lines are rivers, dashed gray lines are state boundaries, the green patch is the Atlantic Rain Forest and the yellow patch is the semiarid Caatinga. b) and c) reduced median network for southern and northern lineages based on b) 1702 bp concatenated mtDNA and c) 1331 bp concatenated nDNA. Each haplotype is represented by a circle and the area of the circle is proportional to its frequency. Samples from different localities are mentioned in different colors as well as same colors/localities relationship is replicated along this paper, Abaeté (dark blue), Guarajuba (green), Costa do Sauípe (brown), Costa Azul (purple), Reserva do Caju (red), Pirambu (light blue), and Parque Nacional da Serra de Itabaiana (PARNASI; yellow). The length of each branch is proportional to the number of mutational steps on the respective branch ("one" was suppressed). The # indicates that the line has been broken to the convenient arrangement of the each nodes.
