The post-cercarial development of G. crumenifer (Creplin) has been experimentally elucidated.
Gyraulus convexiusculus (Hutton) serves as the intermediate host under natural conditions.
The adult stage of the fluke was raised experimentally in ruminants, the time taken by the parasite to attain maturity being 118 days in the kid and 114 in the buffalo calf.
Cercaria chungathi Peter & Srivastava, 1955, has been established to be the larva of Gastrothylax crumenifer. The cercaria, the redial parthenita and the metacercaria have been described.
