It occurs from sea level to 847 m elevation in the Caatinga. It is widely distributed, recorded in the Atlantic Forest, Amazon, Cerrado, Pantanal, and Pampas ( Martins & Oliveira 1998 ; Cechin 1999 ; Marques et al . 2001 ; Marques et al . 2005 ; Bérnils et al. 2008 ; Recoder & Nogueira 2007 ; Sawaya et al . 2008 ; Valdujo et al . 2009 ; Nogueira et al . 2010 ). Occurs in moist forested area in Ceará ( Loebmann & Haddad 2010 ) and can also be found in open areas of bushy and arboreal caatinga on sandy soil, but with strong influence of adjacent Atlantic Forest in Sergipe ( Carvalho & Vilar 2005 ). Records in the Cerrado region are mostly associated to riparian forests and sandy soils (Nogueira et al. 2011; Recoder et al. 2011 ). The single record in Caatinga lowlands was in a hydroelectric plant area in Alagoas State, dominated by xerophitic caatinga vegetation. It has fossorial habits, is nocturnal, and feeds mostly on arthropods ( Marques et al . 2001 , 2005 ).
