| udonella australis n. sp. (monogenea), an epibiont on sea-lice from native fish off southern chile. | udonella australis n. sp., an epibiont monogenean living on caligid copepods that infest a native fish, eleginops maclovinus (valenciennes), off chile, south america is described. the species can be separated from other species by its difference in size, especially body size, and the distribution of cephalic glands, vitelline follicles and genital organs. egg-size is intermediate in comparison with that of other species. the posterior attachment mechanism consists of few muscle fibres and clumpe ... | 2002 | 12023563 |
| dispersal of udonella australis (monogenea: udonellidae) between caligid copepods caligus rogercresseyi and lepeophtheirus mugiloidis on chilean rock cod. | udonella australis is a platyhelminth that lives on the surface of the ectoparasite copepods caligus rogercresseyi and lepeophtheirus mugiloidis, which coexist on the chilean rock cod eleginops maclovinus. the absence of a planktonic oncomiracidium stage in the life cycle of udonellids may limit their dispersal ability. however, the high prevalence and intensity of u. australis on c. rogercresseyi suggest they have developed dispersal strategies to compensate for the lack of a free-living larval ... | 2007 | 17539406 |
