摘要：

Sexual dimorphism is a widespread characteristic in lizards, and it has been related to the individual fitness. Sexual dimorphism was investigated in Aspidoscelis costata costata (Squamata) to the south of the State of Mexico, Mexico, relating to its body proportions highly similar within the Teiidae. Study area was located at 1500 m. Adult individuals from mark-recapture study were used. Morphometric characteristics were measured in individuals of A. costata costata: snout-vent length, mass, head length, head width, head height, femur length and interlimb length. Males were larger than females for SVL and mass. At the same body, males had longer heads and femur and shorter interlimb length than did conspecific females. The sexual dimorphism of A. costata costata can be explained by selection sexual selection and fecundity selection.
