Tapeworms (Cestoda: Proteocephalidae) of Australian reptiles: hidden diversity of strictly host-specific parasites Chambrier, Alain De Beveridge, Ian Scholz, Tomáš Zootaxa 2018 2018-08-23 4461 4 477 498 Chambrier & Beveridge & Scholz, 2018 Chambrier & Beveridge & Scholz 2018 [151,384,870,896] Cestoda Proteocephalidae Australophiotaenia GBIF Animalia Proteocephalidea 17 478 Platyhelminthes genus gen. nov.   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.
