Abstract

The life history of Grysoma indica n.sp., a psilostome trematode, obtained experimentally in ducklings, after feeding with metacercariae occurring in the snail Thiara tuberculata, is elucidated. Natural infections with cercariae were found in T. tuberculata, collected from a freshwater stream at Visakhapatnam, India. Metacercarial cysts were found in the same and other species of snails in the locality. The new species differs from other species of the genus in the sucker proportions, position of the testes and distribution of the vitelline follicles.
