A new species of Philometra Costa, 1845 (Nematoda: Philometridae) from the freshwater fish (red piranha) Pygocentrus nattereri Kner (Characidae) in Amazonia, Brazil
Original language description
A new nematode species, Philometra nattereri n. sp. (Philometridae), is described from female specimens found in oculo-orbits and nasal cavity of the red piranha Pygocentrus nattereri Kner (Characidae) from five lakes in Central Amazonia, Brazil, collected in 2008 and 2009 (overall prevalence 12%, intensity 1-3 nematodes per fish). Based on light and scanning electron microscopical examination, the new species differs from most other congeners parasitising freshwater fishes in that its oesophageal glandextends anteriorly far anterior to the level of the nerve ring, in the presence of 14 small cephalic papillae arranged in two circles and in having two minute caudal projections. This is the first species of Philometra reported from fishes of the familyCharacidae and the second valid species of this genus parasitic in freshwater fishes of Brazil and South America.
