|Brasilotyphlus dubium |
Correia, Nunes, Gamble, Maciel, Marques-Souza, et al., 2018
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.

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.
