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

Abstract

We revisit the distribution and natural history data of Tachymenis chilensis chilensis (Schlegel, 1837) in Argentina based on compiled and novel records, extending its northern and southern distribution from the previously known localities in Argentina. We recorded two prey items in Argentinean populations: Rhinella rubropunctata, reported for the first time, and Liolaemus pictus. Tachymenis c. chilensis is mainly found in forested habitats, generally near wetlands with abundant populations of amphibians. The latitudinal range occupied by T. c. chilensis in Argentina is similar to that in Chile, but its northern distribution limit reaches the lowest latitudes in Chile. This is probably due to the higher humidity levels in the western slopes of the Andes and the barrier effect of the highest mountain ranges in this area.

Shedding Light on the Dentition and Venom Delivery System of the Rear-Fanged Snake, Galvarinus chilensis chilensis (Serpentes: Dipsadidae: Tachymenini) from Chile

“…Currently, the venom composition of G. ch chilensis is unknown, but clinical manifestations of human bites suggest the presence of toxins with anti-coagulant, pro-inflammatory, and edematogenic effects [ 37 , 38 , 48 ]. Additionally, it has been demonstrated that this species feed on toxic toads such as Rhinella rubropunctata [ 49 ], which suggests that the venom of this snake species may help to rapidly subdue toxic prey (probably avoiding the release of their toxins). In this work, we describe the venom gland of G. ch.…”

New elevational record for Walker’s Slender Snake, Tachymenis attenuata Walker 1945 (Squamata: Dipsadidae), with notes on taxonomy and natural history

“…Diets of Slender Snakes, medium-sized opisthoglyphs with attenuate bodies that can be active either by day or night in both terrestrial and arboreal situations, consists mainly of amphibians and lizards (Walker 1945;Giraudo et al 2012). Information about the diets of Bolivian snakes is scarce and only a few reports address prey taken by colubrids and dipsadids (Quinteros-Muñoz et al 2010;Miranda et al 2015;Quinteros-Muñoz 2015, 2021a, 2021b.…”
