Resumo Neoechinorhynchus pterodoridis n. sp. (Acanthocephala: Neoechinorhynchidae) é descrito do intestino de um peixe de água doce chamado "bacu liso" (Pterodoras granulosus (Valenciennes) coletado no rio Amazonas próximo à cidade de Manaus, Amazonas, Brasil. A nova espécie encontra-se entre as menores conhecidas no gênero e na sua forma e tamanho assemelha-se às espécies N. paraguayensis Machado, 1954, e N. golvani Salgado-Maldonado. 1979. A nova espécie distingue-se destas duas espécies pelo pescoço conspícuo que tem e por diferenças notáveis nas medidas dos ganchos.

“…In BL fish, 4 metazoan taxa were found: Genarchella genarchella Travassos, Artigas & Pereira, 1928 (metacercariae); Saccocoelioides nanii Szidat, 1954; Raphidascaris (Sprentascaris) sp. Petter & Cassone, 1984 and Gorytocephalus elongorchi Thatcher, 1979. In WL specimens, 7 taxa were found: Thometrema magnifica, Szidat, 1954; three morphospecies of Proteocephalidae La Rue, 1911 (sp.1, sp.2, and sp.3); Raphidascaris (Sprentascaris) sp. ; Procamallanus (Procamallanus) annipetterae Kohn & Fernandes, 1988 and G. elongorchi. In WL, 100% fish were parasitized, while the prevalence in BL was 96%.…”

Hypostomus commersoni is a freshwater fish, native to the Paraná River basin, which plays an important role in trophic networks of this system. This study aimed at analyzing the structure of the endohelminth community of H. commersoni from two shallow lagoons in the municipality of Santa Fe, Argentina. In the 51 hosts analyzed, 2103 helminths were found. Hosts from Belgrano Park lagoon were infested with Genarchella genarchella, Saccocoelioides nanii, Raphidascaris (Sprentascaris) sp., and Gorytocephalus elongorchi. Hosts from the Western Urban Nature Reserve lagoon were infested with Thometrema magnifica, Procamallanus (Procamallanus) annipetterae, Raphidascaris (Sprentascaris) sp., Gorytocephalus elongorchi, and Proteocephalidae spp. In both host populations, the prevalence of some parasites was high, and species richness and diversity of component communities were low. The distribution pattern of helminth was aggregated in all cases. No correlation was found between the length of the host and the richness and abundance of endoparasites. The total number of parasites and the specific richness per host in both lagoons did not differ significantly. The findings on G. genarchella, P. (P.) annipetterae, G. elongorchi, and Proteocephalidae spp. were the first records in his host

“…Acanthocephalans are endoparasites of fish, birds and mammnal (Cardoso et al, 2017). Gorytocephalus elongorchis Thatcher (1979), a parasite of Loricariidae species (Table 1), was found only in H. ventromaculatos, which are new hosts for this acanthocephalan. Species of Proteocephalus are common cestodes of Siluriformes, which consume planktonic crustaceans (Copepoda and Cyclopoida) that serve as intermediate hosts.…”

The aim of this study was to investigate the parasites fauna of Ancistrus leucostictus, Hypostomus ventromaculatus, Ancistrus sp. and Hemiancistrus sp. from the Igarapé Fortaleza River (Amapá State, Brazil), besides making a checklist of the parasite species in Loricariidae from Brazil. A total of 53 fishes were collected from November 2013 to August 2014. In the hosts, a total of 1,559 parasites of seven taxa were collected: Unilatus unilatus, Trinigyrus mourei, undetermined metacercariae, Genarchella gernachella, Raphidascaris (Sprentascaris) sp., Gorythocephalus elongorchis and Proteocephalus sp. Ectoparasite species were frequent in the examined Loricariidae species, which also had larval stages of endoparasites. The hosts with the highest sampled number, H. ventromaculatus and Ancistrus sp., had the highest parasite species richness. Loricariidae species from Brazil are parasitized by species of Protozoa, Monogenea, Nematoda, Digenea, Acantocephala, Cestoda, Crustacea and Hirudinea, but monogeneans, digeneans and nematodes were the predominant taxa.
