Buntings and New World Sparrows (Emberizidae)

Rufous-rumped Seedeater (Sporophila hypochroma) - HBW 16, p. 659

French: Sporophile à croupion roux German: Rotbürzelpfäffchen Spanish: Semillero Culirrufo
Other common names: Grey-and-chestnut/Rufous-naped Seedeater

Taxonomy: Sporophila hypochroma Todd, 1915, Buena Vista, Santa Cruz, Bolivia.
Molecular evidence suggests that genus is closely related to Oryzoborus, which should perhaps be subsumed within it; further, that both genera should be placed in the tanager family (Thraupidae). A molecular-genetic study of 17 species in genus, including ten in “capped” group (“capuchinos”), indicated that latter form two clades, a N clade largely N of R Amazon containing S. minuta and S. castaneiventris, and a S clade consisting of present species and S. bouvreuil, S. hypoxantha, S. ruficollis, S. palustris, S. cinnamomea and ..

Determination of relationships within the S clade not possible, as genetic differentiation very low and species are apparently part of a very recent and rapid radiation. Monotypic.

Distribution: Locally in N & E Bolivia (Beni, La Paz and W Santa Cruz), SW Brazil (S Mato Grosso and S Goiás), C Paraguay, NE Argentina (E Formosa and E Chaco S to Corrientes, Entre Ríos and N Buenos Aires) and W Uruguay.
