Lowland antpittas

Carneiro L., Bravo G.A., Aristizábal N., Cuervo A.M. & Aleixo A., in press. Molecular systematics and biogeography of lowland antpittas (Aves, Grallariidae): The role of vicariance and dispersal in the diversification of a widespread Neotropical lineage. Mol. Phylogen. Evol.

Abstract
We infer phylogenetic relationships, divergence times, and the diversification history of the avian Neotropical antpitta genera Hylopezus and Myrmothera (Grallariidae), based on sequence data (3139 base pairs) from two mitochondrial (ND2 and ND3) and three nuclear markers (TGFB2, MUSK and FGB-I5) from 142 individuals of the 12 currently recognized species in Hylopezus and Myrmothera and 5 outgroup species. Phylogenetic analyses recovered 19 lineages clustered into two major clades, both distributed in Central and South America. Hylopezus nattereri, previously considered a subspecies of H. ochroleucus, was consistently recovered in a separate clade of uncertain phylogenetic relationships within the Grallaricula/Hylopezus/Myrmothera clade. Ancestral range estimation suggested that modern lowland antpittas probably originated in the Amazonian Sedimentary basin during the middle Miocene, and that most lineages within the Hylopezus/Myrmothera clade appeared in the Plio- Pleistocene. However, the rate of diversification in the Hylopezus/Myrmothera clade appeared to have remained constant through time, with no major shifts over the 20 million years. Although the timing when most modern lineages of the Hylopezus/Myrmothera clade coincides with a period of intense landscape changes in the Neotropics (Plio-Pleistocene), the absence of any significant shifts in diversification rates over the last 20 million years challenges the view that there is a strict causal relationship between intensification of landscape changes and cladogenesis. The relative old age of the Hylopezus/Myrmothera clade coupled with an important role ascribed to dispersal for its diversification, favor an alternative scenario whereby long-term persistence and dispersal across an ever-changing landscape might explain constant rates of cladogenesis through time.

I'm not against an expanded Myrmothera , which absorb Hylopezus and Grallaricula, because there are no generic names available for dives, nattereri and fulviventris/berlepschi clade.

Proposal (785) to SACC

Treat Myrmothera subcanescens as a separate species from M. campanisona

I don't know if I can post this now because it's in review

Carneiro, L., G.A. Bravo, A. Aleixo. Phenotypic similarity leads to taxonomic inconsistency: a revision of the genera Hylopezus and Myrmothera (Passeriformes, Grallariidae), with the description of a new genus from the Atlantic Forest. In review.

If anyone yet has access to this paper can they please advise the name of the new grallarid genus and its type species. All info gratefully acknowledged in the Key.

Will be published in Zoologica scripta but I can't find it in the website

Of course, the type species is ''Hylopezus'' nattereri
