Two new species of Henneguya Thélohan, 1892 (Myxozoa, Myxobolidae), parasitic on the gills of Hoplosternum littorale (Callichthyidae) and Cyphocharax gilbert (Curimatidae) from the Guandu River, State of Rio de Janeiro, Brazil

Two new species of Henneguya (Myxozoa) were described from specimens collected on the gills of Hoplosternum littorale (Hancock, 1828) (Callichthyidae) and Cyphocharax gilbert (Quoy and Gaimard, 1824) (Curimatidae), from Guandu River, State of Rio de Janeiro, Brazil. The species described were compar...
