Distribution: Southern Misiones, Corrientes and Entre Ri'os in Argentina (Bergna et. al. 1992; Giraudo, 

 1994; Kretzschmar, 1998). Also in central and south Brazil, in the States of Para, Brazilia, Sao Paulo and 

 Mato Grosso, Paraguay and Uruguay (Dixon & Kofron, 1983, Achaval & Olmos, 1997). Chaquefia province 

 and Campos district, transition between Espinal and Paranaense provinces in Uruguay river in Entre Rios. 

 Comments: Cited with doubts in Formosa by Williams & Francini (1991). Cei (1993) does not include this 

 species in Argentina.

Constrictor hdiurtnix, 1768. Syn. Rept. 106 

 Type species: Boa Constrictor Linnaeus 1758, Syst. Nat. Ed. 10:215 by subsequent designation Fitzinger, 

 1843: 24. Official generic name # 2019 according to ICZN Op. 1045.

Boa constrictor occidentalis Forcart, 1951. Herpetologica 7 (4): 199. 

 Type locality: Argentina; specified as "Provincias de Mendoza and San Juan", by Stimson,1969. 

 Distribution: Catamarca, Cordoba, Chaco, Jujuy, Formosa, La Rioja, Mendoza, Salta, San Juan, San Luis, 

 Santa Fe, Santiago del Estero and Tucuman (Henderson et al., 1995; Chiaraviglio et al., 1998). Mainly 

 Chaquefia province, although with records in Monte and Espinal. 



Comments: The presence in La Pampa, cited by Orrego Aravena (1971, 1979), is very hard to corroborate. 

 Since the material mentioned by Orrego Aravena (op. cit.) is missing, and since the people in the major part 

 of the province do not remember this species, Tiranti & Avila (1997) consider that it should be excluded 

 from the list of La Pampa reptiles. The same also occurs with Crotalus durissus terrificus, according to these 

 authors.

 Type locality: Forres, Departamento Robles, Santiago del Estero, Argentina.

 Type locality: Gardosa, Ri'o Parana, Paraguay. 



Distribution: Misiones (Henderson et al., 1995; Giraudo, 1997). Paranaense province. 



Comments: Williams & Francini (1991) also included Corrientes, Chaco, Formosa and Salta, but we 

 consider that these references can be due to Koslowsky (1898) and Serie (1921, 1936) who included these 

 provinces before the description of the subspecies crassus and alvarezi- As stated by Cei (1993), the only 

 voucher material is from Misiones. This subspecies may inhabit northwestern Corrientes, but this must be 

 confirmed with vouchers.
