Atractus reticulatus (Boulenger, 1885)
Geophis reticulatus Boulenger, 1885. Ann. Mag. Nat. Hist. 5 (16): 87
Atractus reticulatus scrocchii Alvarez, Rey & Cei, 1992. Boll. Mus. reg. Sci. nat. Torino 10 (2): 251.
Type locality: São Lourenço (at present São Lourenço 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 São
Paulo to Rio Grande do Sul and eastern Paraguay (Bertoni 1939; Alvarez et al. 1992; Lema 1994; Fernandes,
1995). Paranaense province.
Atractus snethlageae Cunha & Nascimento, 1983
Atractus badius Serié, 1915. An. Mus. Hist. Nat. Bs. As. 27: 97.
Atractus flamigerus snethlageae Cunha & Nascimento, 1983. Bol. Mus. Paraense E. Goeldi
(Zool) 123: 19.
Atractus snethlageae Vanzolini, 1986. Relatório Pesquisa N° 1, CNPq. Assesoria Edit. Brazilia: 23-25.
Type locality: Colônia Nova, Rio Gurupi, Estrada BR 316, 10 km before Gurupi, Pará, 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 Serié (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 (Serié, 1915), Pseudoeryx plicatilis (Giraudo,
1997 and in press) and Hydrops triangularis (Williams & Couturier, 1984) were collected in the Paraguay
and Paraná River valleys. The presence of this species in Argentina, supported by only one specimen, merits
the same comments as for Apostolepis assimilis.
Atractus taeniatus Griffin, 1916
Atractus taeniatus Griffin, 1916. Mem. Carnegie Mus.7(3): 173-174.
Type locality: Santa Cruz (probably Santa Cruz de la Sierra), Bolivia.
Distribution: Northeastern Corrientes, Entre Ríos and Misiones. Recorded from Santa Cruz de la Sierra,
Bolivia and Paraná 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 Hidroeléctrica Samuel, Estado de Rondônia, 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.
