''Apalharpactes'' is a genus of birds in the Trogonidae family. They are restricted to humid highland forest on the Indonesian islands of Java and Sumatra. Unlike all other Asian trogons, their plumage is mainly green above and yellow below. Compared to most trogons, the sexual dimorphism is relatively small. The two species in the genus resemble each other, but ''A. reinwardtii'' is larger than ''A. mackloti'', and the male ''A. mackloti'' has a chestnut rump-patch, which ''A. reinwardtii'' lacks. They feed on arthropods, small lizards and fruit. ==Taxonomy== The members of ''Apalharpactes'' are sometimes placed in the genus ''Harpactes'' instead. However a 2010 study found that the two genera are actually distantly related and thus valid.〔Peter A. Hosner, Frederick H. Sheldon, Haw Chuan Lim, Robert G. Moyle (2010) Phylogeny and biogeography of the Asian trogons (Aves: Trogoniformes) inferred from nuclear and mitochondrial DNA sequences ''Molecular Phylogenetics and Evolution Volume 57, Issue 3, December 2010, Pages 1219–1225〕 The two species of ''Apalharpactes'' were formerly treated as conspecific under the name red-billed trogon or blue-tailed trogon (''Apalharpactes reinwardtii'', with ''mackloti'' as a subspecies), but are better treated as separate species.〔Collar, N.
