Furcocercous cercariae infecting freshwater snails in Malabar: two new species from Lymnea luteola Lamarck and Gyraulus convexiusculus (Hutton)
The present paper describes two new species of
furcocercous cercariae, Cercaria sp. XVIII Malabar n. sp.
and Cercaria sp. XIX Malabar n. sp. infecting the freshwater
snails, Lymnea luteola and Gyraulus convexiusculus
respectively in the Malabar region of Kerala. Cercaria sp.
XVIII Malabar n. sp., is a distome, pharyngeate, nonocellate,
longifurcate furcocercous cercaria with two pairs
of penetration glands and 16 pairs of flame cells and
recovered from L. luteola. Cercaria sp. XIX Malabar n. sp.,
is also a distome, pharyngeate, longifurcate cercaria with a
pair of unpigmented eyespots and 20 pairs of flame cells
and recovered from G. convexiusculus. Sporocysts of both
the cercariae developed in the digestive glands. The present
paper describes the cercariae and compares them with
related species to establish their systematic position
