Generally considered conspecific with L. elegans, but trend since 1992 to treat the two as separate species is upheld here, as present species differs in its (in male) all-yellow breast vs black scales joining across breast in distinct band (2); (in female) lack of black in cap, so that crown appears almost concolorous with upperparts (2); song, although fundamentally similar, has fewer notes per strophe (5–8 vs 8–15) (1), and longer notes (1.07–1.3 s vs 0.65–0.9 s) (2), showing less depth in frequency (ns[1]) and with a narrower frequency range of single notes (ns[1])#R. Proposed races venezuelense (W Venezuela) and cadwaladeri (NW Bolivia) commonly recognized, but proved impossible to diagnose in recent review#R. Monotypic.

Distribution:

Locally in foothills of Andes in W Venezuela (Táchira, Barinas), NC & S Colombia (Boyacá; S from S Huila), Ecuador, Peru (Amazonas to Madre de Dios) and NW Bolivia (La Paz, Beni).
