VIII. Sprostonia, a new genus of freshwater Tetraonchinae, with the descriptions of four new species, from the gill filaments of fishes, from Lucknow
Published online by Cambridge University Press: 06 April 2009
A new genus, Sprostonia, is erected in the Family Dactylogyridae, subfamily Tetraonchinae, from the study of trematodes of some Indian freshwater fishes, from Lucknow, India. The new genus differs from allied genera by the characteristically two-piece shape of the ventral bar, the articulation of the cirrus and accessory piece together at the base and the presence of a dextral vagina. The genotype S. indica sp.nov. was recovered from the gills of Eutropiichthys vacha. Three other new species, S. wallagonia, S. gomtia and S. asiatica, were also recovered from other Indian fishes and assigned to the new genus. The text is illustrated with twenty-one camera lucida figures and is followed by a key to the species of the new genus, Sprostonia.
