Widespread in South America: Argentina, Brazil, Colombia, French Guiana, and Suriname (Reyes-Castillo 1973).
Comments. Luederwaldt (1931) and Ivie & Gillogly (1998) recorded this species from Cuba, but we have never seen specimens from this island. Galindo-Cardona (2003) comments that S. cretaus is the only Passalidae in Puerto Rico. Chalumeau & Gruner (1974) noted that it has been collected in rotting logs of Bursera icica (Burseraceae).
