Río Mato, lower Caura, Bolívar, Venezuela.
Until recently considered conspecific with S. stenorhyncha, S. turdina, S. aenea and S. veraepacis. Differs from S. stenorhyncha and S. aenea in characters given under those species. Differs from S. turdina in its olive vs rufescent-brown crown (1); more olive-toned vs brown-toned wings, rump and tail (1); much shorter 2-note song consisting of long note, upslurred at end (3), and very brief note vs 3-note song with last two notes shorter than first, both upslurring (3). Differs from S. veraepacis in olive-brown vs rufescent-brown on throat, breast and upper belly (2); pale olive vs yellow-tinged olive lower belly (1); olive vs warmer but greener olive upperparts (1); similar song, but second note even shorter (1); despite shortfall in score, species rank vs veraepacis provisionally accepted here (a) given interposition of species-rank taxa between these two and (b) pending further study. Monotypic.
