title: Two species of heterophyid larval digeneans from a thiarid gastropod Thiara tuberculata (Müller) from India.
abstract: Two species of heterophyid cercariae, cercaria of Haplorchis taichui and Haplorchis pumilio are obtained from Thiara tuberculata from Visakhapatnam, India. This is the first report of cercariae of both the parasites from India. The characteristic features of H. taichui cercaria are the presence of two sets--one set of lateral and other dorsoventral cuadal finfolds, 15 acicular spines in three alternating rows and seven pairs of lobed penetration glands arranged in two longitudinal rows. H. pumilio cercaria is characterized by the presence of two sets of caudal finfolds, 15 acicular spines in three alternating rows and seven pairs of voluminous unicellular penetration glands.
