PATTERNS OF MERISTIC VARIATION AMONG PARTHENOGENETIC TEIID LIZARDS (GENUS CNEMIDOPHORUS) OF THE YUCATAN PENINSULA AND THEIR PROGENITOR SPECIES, C-ANGUSTICEPS AND C-DEPPEI

We used canonical variate analysis (CVA) to determine the pattern of m eristic variation among Cnemidophorus cozumela, C. maslini, and C. rod ecki, parthenogenetic species from the Yucatin Peninsula, and C. angus ticeps and C. deppei, gonochoristic species implicated in their origin . Cnemidophorus maslini from Campeche, Mexico had the least meristic r esemblance to the progenitor species. Cnemidophorus cozumela was most similar to C maslihi 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 C VA examined the meristic variation among the three parthenogenetic spe cies, with C. maslini partitioned into three statistically distinguish able (sabsidiary) groups. There were significant differences among C c ozumela, 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 parthen ospecies.
