Comment | Synonymy originally that of PETERS & OREJAS-MIRANDA 1970. Some sources called this species “Lasalle's Fishing Snake “ but there is no evidence the species eats fish (Pyron et al. 2016).
Similar species: Some specimens of S. bogerti and S. zamora were referred to S. lasallei by Pyron et al. (2015), prior to the description of those taxa. |
