A new species of the recently described genus Habeas is described. The genus is the single urocoptid representant in Brazil. The new species is named as Habeas centroris, occurring in Paz de Salobro, Canarana, Bahia, Brazil. It is mainly characterized by its dense, delicate sculpture, peristome slightly centrally positioned. Its anatomy is similar to what is currently known, differing mainly by small pallial gland, short stomach, presence of anterior duct to digestive gland, vas deferens very posteriorly originated, prostate lying further the vas deferens origin, and visceral ganglia connected directly to pleural ganglia. The new species is another example of how weak the knowledge on the land mollusks in central Brazilian semi-dry region is, a biome that deserves protection. https://zoobank.org/0DD6D7B5-60C4-42F4-BA72-A4A229D8C92E.
