Interesting to see where Pampagyps description will be published.

Yes, but until the publication is published, the names Panpagyps imperator will be Nomina Nuda,

But we already knew a lot of this new species:

The fossil record of condors in South America is relatively good. However, fossil specimens are scarce for the Late Pleistocene of Argentina. The aim of the present contribution is to communicate a new genus and species of large sized cathartid of the condor lineage. The new taxon is based on a right tarsometatarsus coming from Cantera Vignogna fossiliferous locality, at Marcos Paz District, Buenos Aires Province, Argentina. The fossil was found in the lower levels of the outcrop, characterized by tabular, massive to laminated siltstones which lateral extension is frequently cut by lenticular bodies of highly bioclastic sandstones assigned to the Lujanian Stage/Age (Late Pleistocene). Its size is comparable to Geronogyps and Gymnogyps, being notably smaller than Vultur. Its combination of characters is unique, allowing recognizing a new taxon. An overview of fossil cathartids from Argentine lowlands indicates the existence of several condors that are not closely related to the living South American form Vultur gryphus. The presence of these large cathartids invites to review the fossil record of V. gryphus. The latter taxon has been recorded as fossil from the Pliocene of Buenos Aires, and Pleistocene of Bolivia and Brazil. A review of the Pliocene specimens from Buenos Aires suggests that they belong to an unnamed form not closely related to Vultur. In the same way, specimens from Bolivia are different from living V. gryphus, indicating that they belong to an extinct species. Brazilian records are fragmentary and located near to the locality where the fossil form Pleistovultur nevesi was described. In this regard, we restrict
the record of V. gryphus to the Late Pleistocene of Andean and Patagonian regions.

Abstract:

The fossil record of condors in South America is relatively extensive. However, fossil specimens for the late Pleistocene of Argentina are scarce. Here, we report a new genus and species of a large sized cathartid of the condor lineage. The new taxon, Pampagyps imperator nov. gen. et sp. is based on a right tarsometatarsus from the “Cantera Nicolás Vignogna III” fossiliferous locality, at Marcos Paz County, Buenos Aires Province, Argentina. The fossil was found in the middle levels of the outcrop assigned to the Lujanian Stage/Age (late Pleistocene). Its size is comparable to Geronogyps and Gymnogyps, being smaller than Vultur. Its combination of characters is unique, allowing recognizing a new taxon. An overview of fossil cathartids from Argentine lowlands indicates the existence of several condors that are not closely related to the extant Vultur gryphus. The presence of these large cathartids allows to review the fossil record of V. gryphus. The latter taxon has been recorded in the Pliocene of Buenos Aires Province (Argentina), and the Pleistocene of Estado Plurinacional de Bolivia and Brazil. A review of the Pliocene specimens from Buenos Aires Province suggests that they belong to an unnamed form not closely related to Vultur. Moreover, specimens from Bolivia are different from living V. gryphus, indicating that they belong to the extinct species “Sarcoramphus” patruus. Brazilian records are fragmentary and found near to the locality where the fossil form Pleistovultur nevesi was described. Thus, we restrict the record of V. gryphus to the late Pleistocene of Andean and Patagonian regions.

Cathartidae Lafresnaye, 1839

Pampagyps imperator nov. gen. et sp.

Holotype. MPLK-00001, a complete right tarsometatarsus
Type and only included species. Pampagyps imperator nov. sp.
Age. Lujanian (Late Pleistocene to early Holocene).
Etymology. “Pampa” from the Pampa Region where the holotype was found, and “gyps”, masculine, vulture. “Imperator” from the Latin, which means Commander.

Referred material. MMCIPAS, unnumbered specimen; right proximal end of ulna (Fig. 4). This specimen is referred to Pampagyps imperator on the basis of similar size, and because it comes from a near locality and coeval beds.
