CommentAbundance: rare; Tantilla boipiranga was described based on four specimens from the highlands of Minas Gerais.

Synonymy: although T. boipiranga represents a monophyletic clade oit nests genetically within T. melanocephala 
EtymologyNamed after the words “boi” (= snake) and “piranga” (= red) in the Tupi native Brazilian language. The reddish pattern is shared with T. rubra. T. boipiranga may mimic the similarly colored colubrids of the genus Phalotris.
