Nematodes of Amazonian birds, with a description of Hoazinstrongylus amazonensis n.gen.n.sp. (Trichostrongylidae, Libyostrongylinae)

Abstract

During recent studies of the parasites of birds from the Amazonian Regio, the following nematodes were recovered: Hoazinstrongylus amazonensis n.gen.n.sp. from Opisthocomus hoazin (Muller, 1776); Ascaridia columbae (Gmel., 1790) Travassos, 1913, from Leptotila r. rufaxilla (Richard & Bernard, 1712) representing a new host record; Inglisakis ibanezi Freitas, Vicente & Santos, 1969, Cyrnea (C.) semilunaris (Molin, 1860) Seurat, 1914 and Thelazia digitata Travassos, 1918. A compelte description is restrained to the new genus and new species here proposed. The other known and well described species are listed and accounted.<br>Durante recentes estudos dos parasitas de aves capturadas na Região Amazônica, foram identificadas as seguintes espécies de nematóides: Hoazinstrongylus amazonensis n.gen.n.sp, de Opisthocomus hoazin (Muller, 1776), Ascaridia columbae (Gmel., 1790) Travassos, 1912, de Leptotila r. rufaxilla (Richard & Bernard, 1712) que se constitui em um novo hospedeiro para a espécie, Inglisakis ibanezi Freitas, Vicente & Santos, 1969, Cyrnea (C.) semilunaris (Molin, 1860) Seurat, 1914 e Thelazia digitata Travassos, 1918

Unusual parasite from an enigmatic host – a new group of mites infesting feather quills of the hoatzin

“…Godoy-Vitorino et al 2010, 2012Bardele et al 2017). Haemoparasites were investigated by Renjifo et al (1952), Gabaldon (1998), andPacheco et al (2019); some parasitic nematodes were studied by Renjifo et al (1952) and Pinto and Gomes (1985). Of ectoparasites, feather lice (Mallophaga) (Kellog 1915), and feather mites (Acari) (Atyeo & Gaud 1971;Hernandes & Mironov 2015;Hernandes et al 2017) have been recorded from this enigmatic host.…”

New records for helminths of hystricognath rodents from the middle and high Rio Negro microregion, State of Amazonas, Brazil

“…Moreover, the positive and rising concern related to the maintenance of the biodiversity of the Amazon forest by means of laws to protect the environment and control the studies in these areas has also to be taken into account. Even though some researchers (VICENTE 1964, PEREIRA & MACHADO FILHO 1968, GOMES & PINTO 1978, PINTO & GOMES 1976, 1980, 1984, THATCHER 1991, GONÇALVES et al 2002 had contributed to the knowledge of helminth parasites of non-human hosts, there is a lot more to be investigated so far in the Amazon region.…”
