Abstract
A third species of Brasilotyphlus, a siphonopid caecilian, is described based on six specimens from two twin mountains in Roraima state, northern Brazil. Brasilotyphlus dubium sp. nov.
differs from all other congeners in having a combination of 123–129
primary annuli and 9–16 secondary annular grooves. The first molecular
data were generated and analyzed for Brasilotyphlus, and the genus was
recovered as monophyletic and nested within a paraphyletic Microcaecilia. The extent of genetic and taxonomic sampling, and moderate phylogenetic support are not considered sufficient enough to place Brasilotyphlus in the synonymy of Microcaecilia.
Key words: Brazil, caecilians, phylogeny, taxonomy

Brasilotyphlus dubium sp. nov.
Etymology. The epithet dubium means “dubious”, reflecting our doubt whether or not Brasilotyphlus should be considered a synonym of Microcaecilia. For nomenclatural purposes, the species epithet is considered a noun in apposition.
