Distribution: Buenos Aires, Cordoba, Corrientes, Chaco, Entre Rios and Santa Fe. Also in Uruguay and Rio 

 Grande do Sul, Brazil (Dixon, 1989; Achaval & Olmos, 1997; Giraudo & Quaini, 1997). Pampeana, Espinal 

 and Chaquefia provinces. 



Comments: Reported from Salta (Dixon, 1989), but in the same study, the author questioned that locality. 

 Similarly, this species was reported from Formosa for the first time by Yanosky (1989), then later rectified as 

 Liophis almadensis (Yanosky et al. 1993). Gallardo (1986) reported this species from Misiones. However, all 

 the specimens from the Museo Argentino de Ciencias Naturales, where Gallardo worked are Liophis 

 almadensis, a species that Gallardo did not included in the fauna of Misiones. 



Liophis ceii Dixon 1991 



Liophis ceii Dixon, 1991. Texas J. Sci. 43 (3): 230. 

 Type locality: Near Tucuman, Tucuman, Argentina. 



Distribution: Catamarca, Jujuy, Salta and Tucuman. Also in Santa Cruz and Tarija Departments, Bolivia. 

 Typical of theYungas province. 



Comments: Until the time of their description, this species was considered, and referred to, by many 

 authors, as Liophis poecilogyrus.

Liophis dilepis Michaud & Dixon, 1987. Milwaukee Publ. Mus. Contr. in Bio. and Geo. 71:7. 

 Type locality: Paraguay. 



Distribution: Chaco, Formosa, Corrientes and Santa Fe (Bergna & Alvarez, 1990; Bergna et al. 1992; 

 Yanosky et al. 1993; Giraudo, 1997; Giraudo & Quaini, 1997). The species has a disjunt distribution in 

 northeastern Brazil and southern Brazil, Paraguay, Bolivia and Argentina (Michaud & Dixon, 1987; Lema 

 1989). Chaquena province (mainly Chaco Oriental district). 



Comments: According to Giraudo (1997), the revision of a great number of specimens in Argentinian 

 Museums revealed considerable misunderstanding regarding the identification of the Argentinian species of 

 the L. lineatus group (L. dilepis, L. flavifrenatus and L. meridional is). The same occurs in the literature. 

 Keeping in mind this problem, here we correct the distribution of these taxa in Argentina.
