The type locality is a beach on a rocky poorly vegetated plateau, where the water was dark black with slow current. Individuals were collected at night, approximately between 20:00 and 24:00, during the dry season (October). Stomach contents of cleared and stained specimens were mainly remnants of insect larvae (Ref. 93233). Mattox, G.M.T., R. Britz, M. Toledo-Piza and M.M.F.
