Type species: Bothrops nasutus BOCOURT 1868 is the type species of the genus Porthidium COPE 1871. 
EtymologyNamed after the Latin nasutus meaning "having a large nose," in reference to the upturned snout of the species.

The genus was probably named after Greek portheo (πορθέω), to destroy, ravage, waste, plunder + Greek -idium (–ιδιυμ), diminutive suffix.
