[Tribuliphorus salilotae gen. et spec. nov., a new representative of the monogena]

Belonging to the Monogenean family Diclidophoridae, Tribuliphorus salitotae nov. gen. nov. spec. is described from a gadiform fish, Salilota australia (family Moridae). Its specific characteristics are: big and sharp clasps at the anterior lateral and the posterior lateral plates of the adhesing valves. All 8 valves are structured in the same manner, but they differ in their situation and size: the first 3 pairs are smaller and are inverted (180 degrees to the body's length exis) the hind pair is twice as big and situated normally. --In respect to its morphology, Tribuliphorus nov. gen. could belong to the lowes (most primitive) genera of the subfamily Diclidophorinae, which parasitize the Macruriformes. On the other side, the genus shows affinities to Anchophorus, whose only representative (A. sinensis Bychovsky & Nagibina, 1958) has been found on cynoglossids (an apart group of the Pleuronectiformes), and which has been put in a monotypic family Anchophoridae. By this, the parasitological data again support the previously expressed view (by one of the authors) regarding the relationship of the Pleuronectiformes to the Gadiformes and Goryphaenoididae = Macruriformes).
