Patterns of Meristic Variation among Parthenogenetic Teiid Lizards (Genus Cnemidophorus) of the Yucatán Peninsula and Their Progenitor Species, C. angusticeps and C. deppei

We used canonical variate analysis (CVA) to determine the pattern of meristic variation among Cnemidophorus cozumela, C. maslini, and C. rodecki, parthenogenetic species from the Yucatán Peninsula, and C. angusticeps and C. deppei, gonochoristic species implicated in their origin. Cnemidophorus maslini from Campeche, México had the least meristic resemblance to the progenitor species. Cnemidophorus cozumela was most similar to C. maslini from Guatemala, and C. rodecki was distinguished by its displacement from both C. cozumela and C. maslini and its close resemblance to C. deppei, the paternal progenitor species. A second CVA examined the meristic variation among the three parthenogenetic species, with C. maslini partitioned into three statistically distinguishable (subsidiary) groups. There were significant differences among C. cozumela, C. rodecki, and each subsidiary group of C. maslini. However, specimens of all three subsidiary groups are diagnosable to C. maslini by color pattern, and we consider them to be components of one parthenospecies.
