Abstract: We describe the reproductive pattern of Liophis anomalus based on examination of museum specimens from its entire distribution area. This species shows seasonal activity, although follicles in secondary vitellogenesis were found throughout the year. Our data suggest that multiple clutches occur within a single reproductive period. As in many other snakes, adult females are larger than males when sexual maturity is reached. The sexual size dimorphism index is 0.16, which is consistent with the absence of combat between males (a common feature among species belonging to the Xenodontini tribe). Testicular volume was positively correlated with male size. Clutch size averaged 7.37 eggs, was inversely correlated with mean egg size and positively correlated with female body size. Our results confirm that both phylogeny and climate influence reproductive patterns of this Xenodontini snake.
