Die Geschichte der Gattung Psammodynastes steckt noch voller Geheimnisse. Aufgrund morphologischer Untersuchungen wurde sie erst den Natricinae zugeschrieben. Neuere phylogentische Untersuchungen zeigen, das sie in der Entwicklungsgeschichte, näher Atractaspididae,
Psammophiinae, Boodontina und Pseudoxyrhophiinae verwandt sind. [1]
