A redescription of Sundanonchus behuri (Agrawal & Singh, 1982) n. comb. (Monogenoidea: Dactylogyridea: Sundanonchidae) from the gills of the freshwater Gangetic leaffish, Nandus nandus (Perciformes: Nandidae) in India

Urocleidus behuri [Agrawal N., Singh H.S., On a known and three unknown monogenetic Urocleidus Mueller, 1934. Pranikee 1982; 3: 22–34], described from Nandus nandus in India, is reassigned to Sundanonchus Lim & Furtado [ Lim L.H., Furtado J.I., Sundanonchus g.n. (Monogenea, Tetraonchoididae) from two Malaysian freshwater fishes. Fol Parasitol 1985; 32: 11–19]. Sundanonchus triradicatus Lim & Furtado [Lim L.H., Furtado J.I., Sundanonchus g.n. (Monogenea, Tetraonchoididae) from two Malaysian freshwater fishes. Fol Parasitol 1985; 32: 11–19] is determined to be a junior subjective synonym of U. behuri and a new nomenclatural combination, Sundanonchus behuri is proposed. This article provides a redescription of this new combination, S. behuri [ Agrawal N., Singh H.S., On a known and three unknown monogenetic Urocleidus Mueller, 1934. Pranikee 1982; 3: 22–34], including the previously undescribed egg morphology, based on newly collected specimens from N. nandus in India—a new geographical record.
