Table 2. Differences in coloration, scale counts, and size between Sibon annulatus, S. canopy sp. nov., S. irmelindicaprioae sp. nov., and S. marleyae sp. nov. The range of each continuous variable is from our own sample, Peters (1960), Savage and McDiarmid 1992, Lewis et al. (2013), Lotzkat (2014), and Meneses-Pelayo et al. (2016). The numbers in parentheses represent the sample size.
