Reproductive biology and food habits of Pseudoboa nigra (Serpentes Dpsadidae) from the Brazilian cerrado. Herein we provide data on body size, sexual size dimorphism, reproductive cycle, and food habits of the pseudoboini snake Pseudoboa nigra, wich is dissections of 147 preserved specimens, it is shown that femmales attain, and mature at, larger body sizes than males. There is no significant sexual dimorphism in head lenght, but males have longer tails to their body sizes. Vitellogenesis, egg-laying, and sperm production occur throughout the year, but males do not exhibit long-term sperm storage. The main prey of P. nigra is lizards; there is no evidence of ontogenetic change or sex differences in the diet of this species.
