    Cestodes of the order Trypanorhyncha Diesing, 1863 from South-east Asia and Australia
    SCHAEFFNER, BJOERN ( 2013)
    The objective of the present thesis was to carry out a detailed morphological study of trypanorhynch cestodes from the Australasian and Indo-Malayan regions, in order to increase the knowledge of the species diversity of this particular group of tapeworms. Special focus was thereby paid to four key genera, namely Prochristianella Dollfus, 1946, Dollfusiella Campbell & Beveridge, 1994, Otobothrium Linton, 1890 and Parachristianella Dollfus, 1946. Based on newly collected material from taxonomic surveys in Borneo and Australia, it was possible to provide detailed taxonomic descriptions of species new to science, redescriptions of already described species and/or new information on host range and locality records. The geographical distribution of 35 trypanorhynch species from the four key genera that occur in South-east Asia and/or Australia was assessed and possible ecological factors, such as the host specificity and temperature preference, which may have impacts on the distributional patterns were discussed. In conclusion, the present thesis has contributed significantly to our knowledge of the species diversity of trypanorhynchs from Australia and Borneo and furthermore increased the knowledge on the geographical distribution and host range of selected trypanorhynch taxa.
