The paper supplements a taxonomic revision of the New World species of Pouzolzia by Wilmot-Dear and Friis in 1996 and a supplement in 2011 with an additional new species. Here another new species of Pouzolzia, P. saxophila Friis, Wilmot-Dear & A. K. Monro, is described from a restricted area of xerophytic scrub vegetation on rocky outcrops in the Boa Nova National Park, Bahia, Brazil. The new species is somewhat similar to P. pringlei, a Mexican endemic, and to P. amambaiensis from the Brazil–Paraguay border, but also to the widespread Asiatic P. zeylanica. However, the similarities with these species are probably due to adaptation to similar dry habitats on rocky outcrops.
