Tantilla melanocephala Cope, 1861. Proc. Acad. Nat. Sci. Phila. 1861: 74. 

 Type locality: America 



Distribution: Corrientes, Entre Ri'os and probably Misiones (Vuoto, 1995; Giraudo, 1997; Montanelli & 

 Alvarez, 1997). Occurs from Central America to northern Argentina. Paranaense, Chaquefia and Espinal 

 provinces. 



Comments: Cunha & Nascimento (1993) synonymized the two subspecies. In Argentina, it was reported 

 from Chaco, Misiones and Corrientes (Koslowsky, 1898; Serie, 1921, 1936; Abalos & Mischis, 1975); 

 however, Williams & Francini (1991) and Cei (1993) did not include the species in the Argentinian 

 herpetofauna. There are no Misiones vouchers in Argentinian museums (Giraudo, 1997), but the species 

 probably occurs because it is present in Corrientes and bordering regions.
