摘要:Liophis sagittifer sagittifer (Jan 1863) is a
medium-sized colubrid snake (maximum SVL
~1020 mm) distributed in Argentina, Paraguay,
and Bolivia (Dixon and Thomas 1982; Giraudo
and Scrocchi 2002). Is a diurnal terrestrial snake
found in Patagonica, Monte and Pampeana
phytogeographic provinces that intergrades with
Liophis sagittifer modestus in Espinal and
Chaqueña provinces (Giraudo and Scrocchi 2002).
Southernmost record of this species is by
Koslowsky (1896), who mention the existence
of specimens in Chubut but without any
specific locality. Later, Dixon and Thomas (1982)
indicates five records of L. sagittifer sagittifer
south of province of La Pampa, in central
Argentina but all from bibliographic sources.
These authors marked a point near the boundaries
of provinces of Rio Negro and Chubut at
approximately 42° S latitude. According to
Cei (1986) the southern distribution limit is
peninsula de Valdes, in northeastern Chubut. In a
recent field guide (Scolaro 2005) the general
geographic distribution marked is north of Chubut
river.
