Taxonomy
Erythrolamprus albertguentheri was originally described as Liophis guentheri by Peracca in 1897. Studies by Grazziotin et al. in 2012 found that the species should be reassigned to the genus Erythrolamprus. However, the scientific name Erythrolamprus guentheri was preoccupied by another Erythrolamprus guentheri which had been described by Garman in 1883. Therefore, Grazziotin et al. created the replacement name Erythrolamprus albertguentheri so as to differentiate the two species while maintaining the homage to Günther which Peracca had intended.
