Abstract

BRITO-PORTO, Daniel; SILVA-DE SOUZA, Amanda Karen  and  OLIVEIRA-MALTA, José Celso de. A new species of Neoechinorhynchus (Eoacanthocephala: Neoechinorhynchidae) from the freshwater fish Ageneiosus inermis (Siluriformes) in the Brazilian Amazon. Rev. Mex. Biodiv. [online]. 2017, vol.88, n.4, pp.798-800. ISSN 2007-8706.  http://dx.doi.org/10.1016/j.rmb.2017.10.023.

This work describes a new species of the genus Neoechinorhynchus, a parasite found in the Siluriformes fish, Ageneiosus inermis collected in Catalão Lake. This species is most closely related to N. (N.) pterodorides and N. (N.) pimelodis than other species registered in Brazil. The size of its trunk, hooks and male reproductive system distinguish it from these 2 species. This work contributes to increase the knowledge of the biodiversity of fish parasites in the Amazon.

Keywords : Fish parasite; Ageneiosus inermis; Solimões and Negro rivers; Catalão Lake; Amazon.
