Spinitectus asperus and Klossinemella iheringi , intestinal nematodes of Prochilodus lineatus (Pisces, Prochilodontidae) from the alluvial plain of the Middle Paraná River, Argentina.

Prochilodus lineatus has been considered an ecosystem engineer in the Neotropics given its influence on important ecosystem processes, and it is therefore relevant to understand their inter-specific relationships. The association of P. lineatus with parasitic helminths was studied in two isolated shallow lakes of the alluvial plain of the Middle Paraná River.
