A distinctive form of uncertain affinities, considered to be most closely allied to the bleeding-heart group (G. luzonica and allies) and to G. rufigula; has been placed in its own subgenus, Diopezus, by some authorities. Two S forms bimaculata and auripectus are rather distinct from nominate, with broken, not complete, chocolate-russet hindcollar (not a striking difference; 2); yellowish vs whitish forehead (but this not fully constant; thus 1); grey vs brown on basal two-thirds of rectrices (except central), so dark subterminal bar shows more distinctly (2). Form auripectus perhaps inseparable from bimaculata#R#R. Three subspecies recognized.
