The White-tailed Flycatcher Cyornis concretus has been shown in several phylogenetic analyses to be a very divergent branch within Niltavinae (e.g., Sangster et al. 2010, 2021b, Zhao et al. 2023), and is thus now placed by WGAC in the new genus Leucoptilon Sangster et al., 2021, as Leucoptilon concretum, aligning with Gill et al. (2022, IOC v.12.1).
