Taxonomic note
This new species was described by Irham et al. (2020) from Alor Island, Indonesia. It is most similar to M. kuehni but differs in plumage, voice and genetics. This new species differs from M. kuehni as follows: deeper red on head (1), less extensive red on hood (3), greyer breast (1), well-documented distinctive call (at least 2) and apparently song (a further score, insufficient evidence at present). Monotypic.

Population justification: The population size of this range-restricted species has not been directly estimated. Overall it is described as scarce by Eaton et al. (2021), but it was locally common at a site discussed in Irham et al. (2020). It appears to have specific habitat requirements (Eucalyptus woodland on ridgetops) and remaining available habitat may now total only 50 km² (out of a total area of 120 km² of woodland in its elevational range). The only density estimate available for an Asian species of Myzomela is that of M. dammermani from Sumba, for which Jones et al. (1995) reported 120 individuals/km², thought broadly to be equivalent to c.80 mature individuals/km². Based on descriptive reports of their abundance in Eaton et al. (2021), the densities of these two species are thought comparable, although this requires confirmation. Allowing for some uncertainty with this density (comprising 0.75 and 1.25 adjustments to generate minimum and maximum values), the population of M. prawiradilagae is inferred to number 3,000-12,000 mature individuals (with a best estimate of 4,000-9,999), based on an occupied area spanning 50-120 km² .

Trend justification: The population is suspected to be declining due to ongoing forest loss. Between 2010 and 2020, forest loss in this species' range was estimated at 6-8% (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein) and, as a forest-dependent species (apparently with particular habitat requirements [Irham et al. 2020]), it is thought to be declining at a rate broadly similar to that of forest loss. In 2021, the rate of forest loss appeared to increase substantially, with 2.42 km² of forest in this species' mapped range being lost, comprising a reduction of 2.0-4.8% (depending on the total area of suitable habitat adopted [Irham et al. 2020]) of available habitat in a single year. The species is thought to be suffering ongoing population reductions of 5-15% every 10 years, although this requires confirmation and urgent monitoring.
