[Demonstration of the comparative relationship of the fish genus Merluccius on the basis of parasite infestation].

Continuing the discussion on the theory of SZIDAT (1961) on the development and propagation of the genus Merluccius Cuvier & Rafinesque proved by infestation of parasites the digenean species Elythrophalloides merlucci SZIDAT, 1955 was investigated and declared as a synonym of Elythrophallus (Parahemirus) oatesi (leiper & Atkinson, 1914), together with Elytrophallus (P.) australis (Woolcock, 1935) and E. (P.) lovettiae (Crowcroft, 1947). Probably this species was distributed on the Pacific Coast of Gondwana. The far distances of to day distribution are to be proved by the continental drift. In favour of a northatlantic centre of development the point of view of SZIDAT is declined according to Ho (1974).
