A new species of Rhabdochona Railliet, 1916 (Nematoda: Rhabdochonidae) from cyprinid fishes in the Western Ghats Region, India.

A new nematode species, Rhabdochona (Globochona) puntii n. sp. (Rhabdochonidae), is described based on specimens collected from the intestine of the pool barb Puntius sophore (Hamilton) and Neolissochilus hexastichus (McClelland) (both Cyprinidae) from the Gadhena River, the Western Ghats, Maharashtra State, India. The nematode was also found in Wallago attu (Bloch & Schneider) which probably acts as postcyclic host. Rhabdochona (Globochona) puntii n. sp. differs markedly from its congeners in the body size, the number and distribution of caudal papillae, in the presence of an unpaired papilla-like structure on the anterior cloacal lip, and in having unusual shape and structure of the terminal crown of mucrons. This is the seventh species of the subgenus Globochona Moravec, 1972 reported from freshwater Indian fishes.
