CommentSynonymy mostly after PETERS & OREJAS-MIRANDA 1970. Four species of Dipsas were described (by Cope 1899; Prado 1940, 1941; Werner 1916) and were found to be juveniles of D. pratti (the differences reported only reflected ontogenetic changes, Peters 1960).

Conservation: known from only 13 specimens (including the holotype) [BARROS et al. 2012].
