|Reproduction||Parthenogenetic species. Aspidoscelis rodecki and the A. cozumela complex are diploid unisexuals of the cozumela species group. Both taxa are of hybrid origin, with A. deppii and A. angusticeps being the probable bisexual ancestors (Fritts, 1969; Moritz et al., 1992; Hernandez-Gallegos et al., 1998). Based on mtDNA evidence, Moritz et al. (1992) determined that A. rodecki and the A. cozumela complex were independently derived from an A. angusticeps maternal ancestor. The A. cozumela complex includes several distinct clonal lineages (Fritts, 1969; Moritz et al., 1992; Hernandez-Gallegos et al., 1998) [REEDER et al. 2002].|
|Types||Holotype: UCM 15364 (University of Colorado Museum), collected by T. Paul Maslin, C. J. McCoy, Jr., Lewis A. Pennock, and Hugo G. Rodeck on June 22, 1961.|
|Comment||Group: Belongs to the Aspidoscelis cozumela group (fide REEDER et al. 2002).|
Karyotype: The karyotype of A. rodecki has a diploid number of 50 chromosomes, and exhibits a marked structural heteromorphism. The unique arrangement seems to have originated by Todd ́s fission after the origin of parthenogenesis (hybridization between A. angusticeps and A. deppii) [Manríquez-Morán and Méndez-de la Cruz 2012].
Diagnosis. A small race of Cnemidopho- rus cozumelus characterized by a distinctive gray-blue color, with two pairs of interrupted lateral stripes that become progressively more disrupted with age, white or blue-white subcaudal and subfemoral surfaces and by the presence of no more than one accessory frontoparietal scute.
Distribution: not in Yucatan state (Mexico) according to GONZÁLEZ-SÁNCHEZ et al. 2017.
|Etymology||Named after the collector of the type, Hugo G. Rodeck.|
