Argentinian snakes

7
Distribution: Southern Misiones, Corrientes and Entre Ríos in Argentina (Bergna et. al. 1992; Giraudo,
1994; Kretzschmar, 1998). Also in central and south Brazil, in the States of Pará, Brazilia, São Paulo and
Mato Grosso, Paraguay and Uruguay (Dixon & Kofron, 1983, Achával & Olmos, 1997). Chaqueña province
and Campos district, transition between Espinal and Paranaense provinces in Uruguay river in Entre Ríos.
Comments: Cited with doubts in Formosa by Williams & Francini (1991). Cei (1993) does not include this
species in Argentina.

Constrictor Laurenti, 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, Córdoba, Chaco, Jujuy, Formosa, La Rioja, Mendoza, Salta, San Juan, San Luis,
Santa Fe, Santiago del Estero and Tucumán (Henderson et al., 1995; Chiaraviglio et al., 1998). Mainly
Chaqueña 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.

Epicrates cenchria crassus Amaral, 1929. Mem. Inst. Butantan 4: 140.
Type locality: Gardosa, Río Paraná, 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 Serié (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.
