In past, traditionally treated as an outsize family that also included expanded versions of Sylviidae, Timaliidae and Turdidae; these three were subsequently split off as three separate families, but still in much expanded form as compared to their current treatment. Since publication of HBW, limits of all these families have been dramatically rewritten due to a barrage of occasionally contradictory molecular data. Within present family problems remain, particularly due to incomplete taxon sampling, but near-complete screening to species level has now been attempted for at least a handful of genera (notably Oenanthe and Saxicola), and large elements of consensus have emerged, among them the recognition of four principal lineages, here treated as subfamilies. Most notable development involves transfer of many genera from Turdidae to present family, including Alethe, Cichladusa, Heteroxenicus, Brachypteryx, Heinrichia, Myophonus, Monticola, Thamnolaea, Myrmecocichla, Pogonocichla, Swynnertonia, Stiphrornis, Sheppardia, Cossypha, Xenocopsychus, Irania, Luscinia, Erithacus, Tarsiger, Cercotrichas, Copsychus, Phoenicurus, Saxicola and Oenanthe. Genetic sampling has also revealed extensive paraphyly, with the result that many species have switched genera. Some genera have disappeared completely into synonymy (e.g. Erythropygia), and others have shrunk to just one or two species (e.g. Luscinia), while a few have become substantially larger (e.g. Cercotrichas, Oenanthe).

Genus: Oenanthe Vieillot, 1816

Extensively tested in recent molecular studies, where some species complexes show very low (sometimes virtually no) genetic differentiation, making assessment of species limits using such methodology alone extremely difficult#R #R #R #R #R #R; this research has also revealed notable paraphyly with other closely related genera, resulting in: inclusion herein of most species formerly treated in Cercomela, and one hitherto placed in Pentholaea, as well as removal of one species from Oenanthe to Myrmecocichla.
