Ecological notes.

Fossorial and diurnal (Rodrigues 1991c; Rocha and Rodrigues 2005). It inhabits sand soil patches and dunes, much typical on both sides of the São Francisco River (Rodrigues 1991c; Delfim et al. 2011). Diet based mainly on arthropods, being Araneae, Thysanura, and Orthoptera the most representative items (Rocha and Rodrigues 2005). Oviparous, no detailed data is known about the number of eggs laid by the species, but it could be similar to other Procellosaurinus species (Ramiro et al. 2017).
