Newly described species#R, closest morphologically and genetically to H. spodiops, but differing in its shorter crown feathers (morphometric character; 1); brownish tinge confined to loral and supraloral region vs all face (1); concolorous olive head and back vs vague brown/green contrast between these two (1); two distinct bronzy wingbars and panel in folded wing formed by pale edges to secondaries (2); and five vocalizations all apparently distinctive, including a loudsong that is much shorter (2), lower-pitched (3), slower-paced (ns[2]) and with fewer notes (ns[2]). Monotypic.

Distribution:
