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).
