Taxonomic note
Myiomela albiventris and M. major have been moved to the new genus Sholicola after they were found to be sister to a newly uncovered clade composed of several genera of mainly Asian blue-flycatchers (Robin et al. 2017). They have also received new common names, and are listed as White-bellied Sholakili Sholicola albiventris and Nilgiri Sholakili S. major.

Population justification: The global population size of this species has not been quantified, although it has a localised and scattered distribution in the Western Ghats (eBird 2023, SoIB 2023), and may therefore have a population size that is moderately small.
Trend justification: Presumably much declined from historical baselines given the significant removal of habitat from within its range (see Reddy et al. [2016] for summary of forest cover changes in the Western Ghats between 1920 and 2013). There are no monitoring data from which to derive a current trend for this species, although it is precautionarily suspected to be declining, albeit at a slow rate. Habitat loss and degradation has been slow over the past decade (2013–2023) according to remote sensing data (Global Forest Watch 2023, based on data from Hansen et al. [2013] and methods disclosed therein), although these analyses are relatively insensitive to forest degradation or modifications that don't affect the forest canopy. Modelling for this species' only congener, Sholicola albiventris, projected that the latter would lose a significant amount (26.6–44.9%) of habitat in response to climate change by 2050 (Sreekumar and Nameer 2022). While this modelling approach has not been applied to the present species, given the similarity of the two and their ecological niches, it might reasonably be expected that climate change is affecting this species now, or will do so in the near future.
