The snakes were captured between 2008-2014 in the Chapada do Araripe in northeastern Brazil, and were collected by active visual searches, as well as in pitfall traps with drift fences. Although females are larger than males, the males have longer tails, and scale counts differ between the sexes. Reproduction is seasonal, occurring during the rainy season. Brood sizes rang from one to four eggs. Atractus ronnie preys on earthworms, in addition to ants (Crematogaster sp.) and insect larvae.77-87engCerradodietsexual dimorphismhabitsreproductionArtigo10.11606/issn.2316-9079.v18i1p77-87WOS:000472541200007Acesso restrito
