Classification
editErythrolamprus zweifeli belongs to the genus Erythrolamprus, which contains over 50 species. The genus Erythrolamprus belongs to the subfamily Dipsadinae, which is sometimes referred to as the family Dipsadidae.
Erythrolamprus zweifeli was previously considered to be a subspecies of Erythrolamprus reginae and called Erythrolamprus reginae zweifeli. However, based on notable differences in coloration and scale counts, it is now considered to be a separate species.[3] This close relationship to Erythrolamprus reginae, as well as the relationships of Erythrolamprus species located in northern South America, can be shown in the cladogram below, based on molecular DNA analysis:[3]
