Distribution and natural history notes on Tachymenis chilensis chilensis (Schlegel, 1837) (Reptilia: Serpentes: Dipsadidae) in Argentina

“…Our records extend the distribution of T. chilensis with precise localities and vouchers to the province of Chubut, where the species was mentioned by Scrocchi et al (2010) but without voucher specimens. Several localities represent the southernmost and northernmost records of this species in Argentina (Ortiz 1973;Cei 1986;Williams and Scrocchi 1994;Giraudo and Scrocchi 2002;Scrocchi et al 2010; Figure 1). The range of altitude occupied by T. chilensis in Argentina appears to vary from 200-2000 m a.s.l.…”
