Extract

Artyfechinostomum Lane, 1915 (type A. sufrartyfex Lane, 1915) is a synonym of Paryphostomum Dietz, 1909 (type P. radiatum Dujardin, 1845). While the general morphology of the two forms is similar and places them both in the family Echinostomatidae, other characters clearly place them in different genera of this family. In Artyfechinostomum the cirrus-sac extends far posterior to the acetabulum, and the right and left fields of vitellaria in the post-testicular region are confluent. In Paryphostomum the cirrus-sac is small and anterior to the middle of the acetabulum and the vitellaria in the post-testicular region are not confluent. These differences entitle Artyfechinostomum to be placed in a separate genus. The species Paryphostomum indicum Bhalerao, 1931 and P. mehrai Jain, 1957 are transferred to the genus Artyfechinostomum.
