FIGURE 4 in A likely microendemic new species of terrestrial iguana, genus Chalarodon, from Madagascar

FIGURE 4. Boxplots comparing selected morphometric measurements and scale counts among Chalarodon madagascariensis (left, A, dark brown) and C. steinkampi sp. nov. (right, B, light brown). Plots show relative forelimb lengths (ratios to snoutvent length; RELFOL), number of dorsal crest scales (DCSC), ventral scales from chin fold to cloaca (VEN), scales around midbody (MID), number of cross bars on throat (TCB), and number of scales in contact with mental (NSCM). Test statistics are from non-parametric Kruskal-Wallis comparisons (equivalent to Mann-Whitney U-tests given only two groups are compared). In addition to these scale counts, most of which are statistically different but show overlap in values between the two species, diagnostic differences are found in the keeled vs. smooth state of ventrals and gulars (variables VK and GK in Tab. 3).

FIGURE 5 in A likely microendemic new species of terrestrial iguana, genus Chalarodon, from Madagascar

FIGURE 5. Detailed views on mental region(A–B), belly scales (C–D) and hemipenes (E–F) of Chalarodon steinkampi sp. nov. (ZSM 835/2010) in comparison with C. madagascariensis (ZSM 832/2010). The ulcer-like tubercles on the belly in (C) were not studied but might be due to unidentified parasites. Note the long distal lobe of the hemipenis of C. steinkampi (F) and the pair of distinctly enlarged scales posterior to the cloaca of the males (E–F). Photographs by M. Franzen.

FIGURE 2. Molecular results and geographical context: (A) localities of the specimens of Chalarodon madagascariensis and C. steinkampi sp. nov. included in the molecular analyses. (B) Bayesian phylogenetic tree (see Table 1 for voucher numbers) based on the 16S mtDNA dataset and (C) haplotype network of the nDNA marker c-mos. Circles represent haplotypes (size proportional to the number of individuals), black lines represent mutational steps and black dots missing haplotypes, and brown curves represent connections between haplotypes found co-occurring in heterozygous individuals.
