Figure 2From: Gyrodactylus salinae n. sp. (Platyhelminthes: Monogenea) infecting the south European toothcarp Aphanius fasciatus (Valenciennes) (Teleostei, Cyprinodontidae) from a hypersaline environment in ItalyDrawings of the opisthaptoral hard parts and male copulatory organ (MCO) of Gyrodactylus salinae n. sp. from the south European toothcarp Aphanius fasciatus (Valenciennes) from Cervia Saline, Italy. a - opisthaptoral central hook complex; b - MCO; c, d - marginal hook sickles; e - marginal hook sickle of Gyrodactylus rugiensoides Huyse et Volckaert, 2002 from Pomatoschistus minutus (Pallas) collected from Texel, The Netherlands (re-drawn from the paratype 2002.2.14.2); f - a size invariant overlay of the marginal hook sickles of G. salinae n. sp. (broken line) with G. rugiensoides (solid line); g - a size variant overlay of the marginal hook sickles of G. salinae n. sp. (broken line) with G. rugiensoides (solid line).
