Atractus reticulatus is an oviparous semifossorial snake whose reproductive biologyis barely known. In this work we present information about the nesting sites and egg characteristicsof this species from two sites in the north of the province of Corrientes, Argentina. Differences inclutch size, egg size and sex ratio between the different clutches were observed. Hypotheses areconsidered about oviposition, developmental period of embryos and possible association ofthis snake with ants of the Odontomachus genus.
