Taxonomy and systematics of 2 new species of myxozoans (Cnidaria: Myxobolidae) parasitizing the gills of Iheringichthys labrosus (Teleostei: Pimelodidae) from southeastern Brazil

| Summary: | Abstract
During a survey of myxozoan infections in fishes from the Pardo River, Paranapanema River basin, São Paulo State, Brazil, 2 new species – Henneguya avareensis n. sp. and Myxobolus iheringichthys n. sp. – were discovered parasitizing the gills of Iheringichthys labrosus, a commercially important pimelodid fish in South America. Species descriptions were based on the morphology of myxospores and partial sequences of the small subunit ribosomal DNA. Phylogenetic analysis revealed host-related clustering, with the new species clustering together with other myxobolids that parasitize Pimelodidae (Siluriformes). Myxobolus iheringichthys n. sp. clustered specifically with Myxobolus cordeiroi, together forming yet another lineage of myxobolids infecting Pimelodidae fishes. Our analysis underscores the importance of monitoring the presence of these parasites in stocks of I. labrosus to assess potential pathologies they may cause. This is the first report of myxozoans parasitizing the gills of this Neotropical catfish.
