Liophis poecilostictus Jan (syn. Pietro, Sánchez, Poljak & Alcalde 2026) |
Remarks:
Now restricted to Argentina and Uruguay.
Previously included the population now assigned to pseudomamba.
Records from Bolivia, Brazil, and Paraguay refer to pseudomamba (Pietro, Sánchez, Poljak & Alcalde 2026).
A single record from Chile (Thomas 1976; repeated by Gouveia, Novelli, Vieira & Sousa 2017) is regarded as doubtful.
The species was not included for Chile in subsequent works (e.g., Núñez 1992; Veloso & Navarro 1988).
Distribution:
Argentina,
Uruguay.
