Tapeworms (Cestoda: Proteocephalidae) of Australian reptiles: hidden diversity of strictly host-specific parasites Author Chambrier, Alain De Author Beveridge, Ian Author Scholz, Tomáš text Zootaxa 2018 2018-08-23 4461 4 477 498 journal article 28967 10.11646/zootaxa.4461.4.2 4088067b-9ee8-4fea-b597-059a9de5b6e2 1175-5326 1460246 838E32FD-05BE-47D4-9CF1-E96E7F1C08FF Australophiotaenia sp. 7 Host. Black-headed python, Aspidites melanocephalus (Krefft, 1864) ( Ophidia : Pythonidae ). Distribution. Australia (West Australia ). Material studied. One fragmented incomplete specimen (five proglottids, one whole-mount) from Perth Zoo, 31.3.1998 ( MUP X 98/02 ). Remarks. This fragmented, incomplete specimen without a scolex is in a poor state of preservation and not suitable for reliable morphological description. This morphotype may represent a new species that is typified by a large cirrus-sac, the length of which represents 45–55% of the proglottid width, i.e. the cirrus-sac may overpass the middle line of proglottid.
