Tachymenis

Tachymenis is a genus of venomous snakes belonging to the subfamily Dipsadinae of the family Colubridae. Species in the genus Tachymenis are commonly known as slender snakes or short-tailed snakes and are primarily found in southern South America. Tachymenis are rear-fanged (opisthoglyphous) and are capable of producing a medically significant bite, with at least one species, Tachymenis peruviana, responsible for human fatalities.

Species

The following species are recognized by the Reptile Database.

Tachymenis ocellata (A.M.C. Duméril, Bibron & A.H.A. Duméril, 1854) – ocellated pampas snake
Tachymenis peruviana Wiegmann, 1835 – Peru slender snake
Tachymenis trigonatus (Leybold, 1873) – false tomodon snake

Most [colubrids] may not produce a venom capable of causing serious damage to humans, but at least five species (Dispholidus typus, Thelotornis capensis, Rhabdophis tigrinus, Philodryas olfersii and Tachymenis peruviana) have caused human fatalities.
