Criniger mysticalis


, 1863,

Buru, south Moluccas


Until recently considered conspecific with T. affinis, but separated on a range of characters from this and closely related T. longirostris#R, differing from T. affinis in its slightly smaller size (effect size for bill length −1.99; score 1); presence of partial yellow eyering (2); olive-green vs yellow belly to vent (3); olive-green vs broad yellow edges and tips of tail (3); and no yellow tips on uppertail-coverts (ns[1]). From the newly defined T. longirostris in its olive-green vs yellow belly to vent (3); considerably smaller size and notably shorter tail (effect size –3.62; 2); half-wedge yellow vs olive-green lores (2); partial yellow eyering (ns[2]); dark olive-grey vs bright yellow-fringed rectrices (3); and narrow whitish vs narrow yellow inner fringes on tertials (ns[2]). From T. lucasi (by extension T. chloris), T. aurea and T. platenae in characters given under those species. Recent published descriptions of song and calls also indicate vocal differences#R. Monotypic.
