Rhynchospiza

Van Remsen has submitted a proposal to AOU-SACC (#456, Aug 2010) to resurrect Rhynchopsiza [sic, but proposal since corrected] for South American "Aimophila".

Good catch :t:
DESCRIPTIONS OF SUPPOSED NEW GENERA, SPECIES, AND SUBSPECIES OF AMERICAN BIRDS

Rhynchospiza!

Yes, well spotted, Daniel.

The downside of copy & paste: instant promulgation of typos!
But hopefully SACC won't actually recognise Rhynchopsiza Remsen 2010.

[Post #1 corrected, but unfortunately it's impossible to edit the thread title.]

Hartert said while describing the subspecies, R. strigiceps dabbenei :
N.B. The systematically identify Z. strigiceps difficult position. In general, type and color of the drawing of the head she has a great resemblance to Rhynchospiza stolzmanni (Tacz.) from NW Peru, however, the proportion of wing and tail are quite different. (google translate)

So, the museum skin ornithologist agree with the DNA ornithologists.

Abstract:

The genus Rhynchospiza comprises two species, the monotypic Tumbes Sparrow (R. stolzmanni) and the Stripe-crowned Sparrow (R. strigiceps) with subspecies strigiceps and dabbenei. In the study reported here we evaluated the taxonomic status of these taxa and discussed key features involved in speciation. All three taxa exhibited multiple differences in plumage, morphology, and vocalizations, supporting the recognition of three species in Rhynchospiza. The very large-billed R. stolzmanni has a song composed of a succession of faster complex trilled phrases, shows a small black loral line and dark-chestnut head stripes with large dark central-stripe to individual feathers, and is resident in the Tumbes region. The large and heavy dabbenei has a song consisting of a series of simple chirping notes, shows a large black loral crescent and chestnut head stripes with a reduced to absent dark center to feathers, and inhabits the Austral Yungas as a year-round resident. The small and pale strigiceps has a song consisting of a succession of complex trilled phrases, shows a small black loral line and rufous-brown head stripes with large dark central-stripe to feathers, and inhabits Dry and Sierran Chaco where it is a partial migrant. Locality data and ecological niche modeling show that dabbenei and strigiceps are allo-parapatric and use different altitudinally segregated habitats at their zone of parapatry. Molecular phylogenetic analyses (NADH dehydrogenase 2 [ND2] gene) revealed R. stolzmanni to be sister (11.5% divergent) to a recently diverged dabbenei and strigiceps clade (1.6% divergent). We conclude that the genus Rhynchospiza comprises three species-level entities, each restricted to a major biogeographic region, and that vocalizations and facial patterns provide key evidence on species limits in these otherwise similarly plumaged taxa. The evolutionary–cultural differences in songs, with complex phrases in those of R. strigiceps and R. stolzmanni, and single notes in the songs of R. dabbenei, suggest changes in the innate vocal learning template during speciation in the latter.
