Podocotyle synechogobii (Qiu & Li) n. comb.

Synonyms: Hamacreadium synechogobii Qiu & Li in Shen & Qiu, 1995 .

Records. From the Asian freshwater goby, Synechogobius ommaturus (Richardson) ( Perciformes : Gobiidae ), in the Bohai Sea ( Shen & Qiu, 1995).

Remarks. Gobiids are not typical definitive hosts of Hamacreadium species and it is clear from the original illustration that this species does not belong in the genus; the genital pore is lateral to the pharynx, the vitelline follicles are restricted to the hindbody and the ventral sucker is only marginally larger than the oral sucker and is immediately posterior to the intestinal bifurcation. The morphology of this species is most consistent with Podocotyle , to which it is transferred here. The only species of Podocotyle previously recorded from gobiids is Podocotyle atomon ( Rudolphi, 1802) Odhner, 1905 , which is morphologically similar but differs in the anterior extent of the vitelline follicles, the length of the cirrus-sac, the relative size of the ventral sucker and the length of the post-testicular and pre-ovarian areas.
