ReproductionAspidoscelis neavesi is the first known tetraploid amniote that reproduces through parthenogenetic cloning by individual females. Aspidoscelis neavesi originated through hybridization between Aspidoscelis exsanguis (triploid parthenogen) × Aspidoscelis inornata (diploid bisexual or gonochoristic species) in the laboratory. The authors speculate that field-caught tetraploids may be found in the future. 
TypesHolotype. MCZ R-192219 (5 SIMR 8093), a cloned adult female of the F2 laboratory reared generation that also cloned herself at the SIMR. She hatched on August 13, 2008, and her mother was MCZ R-192209 (=SIMR 4919). 
EtymologyThe specific epithet, a noun in the genitive singular case, honors Dr. William B. Neaves, who was awarded a Ph.D. at Harvard University. Dr. Neaves’ graduate studies on unisexual whiptail lizards (Neaves and Gerald, 1968, 1969; Neaves, 1969, 1971) provided important early insights into the molecular genetics, origins, and speciation of parthenogens through hybridization, as well as the origin of a tetraploid hybrid lizard of A. exsanguis X A. inornata that he discovered in the field in Alamogordo, Otero County, New Mexico, which was the inspiration for the present laboratory hybridization project.
