Ptilonopus [sic] chrysogaster
G. R. Gray, 1854,
“probably from Otaheite“ = Raiatea, Society Islands.
Belongs to the large species-group centred on P. purpuratus (which see), forming part of the subgroup centred on that same species. Hitherto normally treated as a race of P. purpuratus, but molecular evidence places it closer to P. rarotongensis#R, with which it shares finely emarginated outer primary. Differs from P. purpuratus in greenish-yellow vs yellowish-grey mid-belly to bright yellow vs pale yellow vent, with bright yellow vs yellowish-grey on lower belly (3); pale yellow superciliary line joining behind paler pink crown (very faint line in some P. p. frater) (1); broad clear whitish-yellow terminal tailband vs narrow, vague part-white subterminal band (2); and very finely emarginated outer primary (effect size for narrowest point of emargination –4.66; score 2). Differs from P. rarotongensis by very pale lavender crown with vague yellow border vs strong purple crown with no yellow border (3); lack of reddish upper belly patch (2); blackish broad edges to inner vanes of outer rectrices (1); and marginally longer wing (effect size 2.4; score 2). In past, sometimes considered a race of P. coralensis. Monotypic.
