Atractus reticulatus (Boulenger, 1885)

Atractus reticulatus scrocchii Alvarez, Rey & Cei, 1992. Boll. Mus. reg. Sci. nat. Torino 10 (2): 251. 

 Type locality: Sao Louren^o (at present Sao Louren^o do Sul, according to Lema 1994), Rio Grande do Sul, 

 Brazil. 



Distribution: Corrientes and Misiones in Argentina (Alvarez et. al. 1992; Giraudo, 1997). In Brazil from Sao 

 Paulo to Rio Grande do Sul and eastern Paraguay (Bertoni 1939; Alvarez et al. 1992; Lema 1994; Femandes, 

 1995). Paranaense province.

Atractus snethlageae Vanzolini, 1986. Relatorio Pesquisa N° 1, CNPq. Assesoria Edit. Brazilia: 23-25. 

 Type locality: Colonia Nova, Rio Gurupi, Estrada BR 316, 10 km before Gurupi, Para, Brazil. 

 Distribution: In Argentina, known only from Las Palmas, Chaco. Species of wide Amazonian distribution 

 (Cunha & Nascimento 1983, 1993; Vanzolini, 1986). We suspect that the individual from Las Palmas comes 

 from gallery forests or marginal areas of the Paraguay River included in Paranaense province. 

 Comments: The citation is based on the individual mentioned by Serie (1915), as Atractus badius and which 

 was included in later publications (Cei, 1993; Williams & Francini, 1991). The Amazonian records are more 

 than 1000 km away from the Argentinian locality. In spite of this great distance, other Amazonian and/or 

 widely distributed tropical species such as Imantodes cenchoa (Serie, 1915), Pseudoeryx plicatilis (Giraudo, 

 1997 and in press) and Hydrops triangularis (Williams & Couturier, 1984) were collected in the Paraguay 

 and Parana River valleys. The presence of this species in Argentina, supported by only one specimen, merits 

 the same comments as for Apostolepis assimilis. 



Atractus taeniatus Griffm, 1916 



Atractus taeniatus Griffm, 1916. Mem. Carnegie Mus. 7(3): 173-174. 

 Type locality: Santa Cruz (probably Santa Cruz de la Sierra), Bolivia. 



Distribution: Northeastern Corrientes, Entre Rios and Misiones. Recorded from Santa Cruz de la Sierra, 

 Bolivia and Parana State, Brazil (Griffin, 1916; Mc Coy 1971; Williams & Gudynas 1991; Lema, 1994; Rey 

 & Lions, 1997; Moura Leite et al., 1996; Giraudo & Scrocchi, 2000). Da Silva (1993) mentioned two 

 individuals from Usina Hidroelectrica Samuel, Estado de Rondonia, Brazil, but he noted that the 

 identification was tentative. Paranaense province in Argentina. 



Comments: Although this species has a wide distribution, there exists only a few precise localities and wide 

 areas remain without records.
