Genetic surveys across the range of Forest Robin Stiphrornis erythrothorax consistently reveal a great deal of population structure (as assessed by mitochondrial DNA: Beresford and Cracraft 1999, Schmidt et al. 2008, Voelker et al. 2017, Dongmo et al. 2019), and sympatry is reported between two of these populations (Boano et al. 2015). Therefore we recognize three species, corresponding to the three most deeply divergent clades. The three species we recognize are: a monotypic Olive-backed Forest Robin Stiphrornis pyrrholaemus; a polytypic Orange-breasted Forest Robin Stiphrornis erythrothorax, with subspecies erythrothorax, gabonensis, and xanthogaster; and a polytypic Yellow-breasted Forest Robin Stiphrornis mabirae, with subspecies sanghensis and mabirae. This genus is a complicated taxonomic riddle that requires much further work in the future, with a focus on vocalizations as well as on data from nuclear genes, and with sampling at or near type localities. Also note that we revise the ranges of some taxa, so that the names here applied to some populations may differ from the nomenclature used in the references we cite (especially with regard to xanthogaster).
