Dois novos gêneros e espécies de Paramphistomidae (Trematoda, Vigenea) são descitos de peixes de água doce da Amazônia brasileira. Anavilhanatrema robusta gen. et sp. nov. e caracterizado porter um corpo cilíndrico com uma expansão anterior, ventosas pequenas, uma bolsa de cirro pequena, testículos grandes e lobados, um ovario lobado, cecos longos e glândulas vitelínicas extensivas. Pacudistoma turgida gen. et sp. nov., no entanto, se distingue porter um corpo cilíndrico, uma ventosa oral grande com divertículos internos, uma ventosa genital grande, testículos lobados que são menores em tamanho, um ovario esférico, cecos longos e glândulas vitelínicas que são relativamente extensivas. Ambas espécies parecem ser específicas acanto aos hospedeiros, sendo que A. robusta encontra-se em Pristobrycon striolatus (STEINDACHENER) e P. turgida ocorre em Myleus pacu (SCHOMBURGK). 2020-04-24T15:14:50Z 2020-04-24T15:14:50Z 1992 Artigo https://repositorio.inpa.gov.br/handle/1/13129 10.1590/1809-43921992224613 en Volume 22, Número 4, Pags. 609-613 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica
