Resumo: Dissection of 286 specimens of the "false" coral snake Erythrolamprus aesculapii Linnaeus, 1766, combined with data on captive individuais, provided information on the reproductive biology of this colubrid snake. Adult females (x snout-vent length = 74.5cm) attain larger body size than males (x SVL = 62.6). Clutch size ranged from one to eight eggs and was correlated with maternal body size. Neonates measured 20.2-22.5cm SVL and weighed 5.1-5.8g. Males attain sexual maturity earlier than females. Reproduction seems to be aseasonal, with vitellogenesis occurring throughout the year. Apparently the growth rate of folheies decreases in the dry season, possibly due to lower tempeiatures during this period. Multiple clutches were recorded in captive snakes. Foraging strategies and availability of prey may explain continuous reproduction in E. aesculapii. However, data for other related snakes suggest that continuous reproduction is conservative in the Xenodontini.
