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  ).
