Morphological and molecular taxonomy of a new species of fundulotrema and comments on Gyrodactylus stephanus Monogenea: Although the hamuli roots in gyrldactylus species narrow after their union with the shaft, giving the anterior edge of the dorsal bar attachment point a small but distinct edge, this appears to be more prominent in G.

Connections between the Northern Pacific and Northern Atlantic are even tighter, including common species such as G. The phylogeographic coverage of this lineage is now extended significantly to include the Southern Hemisphere and the Pacific Ocean.

Due to the small fraction of the genus analysed gyrodactyls the above works, little can be said about its systematics. Concurrent invaders – four exotic species of Monogenea now established on exotic freshwater fishes in Australia.
