Phimophis guerini, also known commonly as the Argentine pampas snake, is a species of snake in the subfamily Dipsadinae of the family Colubridae.[4] The species is endemic to South America.

Etymology

The specific name, guerini, is in honor of French entomologist Félix Édouard Guérin-Méneville.[5]

P. guerini has been recorded from open areas and savannas in Argentina, Brazil, and Paraguay.[6]

It has eight upper labials and nine or ten lower labials. The dorsal scales are in 21 rows anteriorly, 19 rows at midbody, and 17 rows posteriorly. The ventrals number about 200. The subcaudals number about 70 (a few more in males, a few less in females).[6]
