Tormopsolus orientalis Yamaguti, 1934 (Digenea: Acanthocolpidae) from Seriola dumerili (Risso) (Perciformes: Carangidae) in the western Mediterranean Sea

摘要

Tormopsolus orientalis Yamaguti, 1934, is redescribed from Seriola dumerili from off Corsica, Majorca and Águilas, SE Spain. The vitellarium is interrupted at the level of the ovary and both testes, and a bipartite seminal vesicle is found in many specimens. Oral sucker papillae are always seen. Type-specimens and voucher specimens from off Japan, Bermuda, Panama, Curaçao and the Great Barrier Reef have been compared with the Mediterranean species. Specimens of T. medius Reimer, 1983, from Mozambique have been studied and this species is synonymised with T. orientalis.
