Phylogenetic relationships of the anoplocephaline cestodes of Australasian marsupials and resurrection of the genus Wallabicestus Schmidt, 1975

A phylogenetic analysis was carried out on rDNA of 45 species of anoplocephaline cestodes from marsupial hosts. The exclusively Australasian genera Progamotaenia Nybelin, 1917, Triplotaenia Boas, 1902, Paramoniezia Maplestone & Southwell, 1923 and Phascolotaenia Beveridge, 1976 formed a monophyl...

Description
Summary:A phylogenetic analysis was carried out on rDNA of 45 species of anoplocephaline cestodes from marsupial hosts. The exclusively Australasian genera Progamotaenia Nybelin, 1917, Triplotaenia Boas, 1902, Paramoniezia Maplestone & Southwell, 1923 and Phascolotaenia Beveridge, 1976 formed a monophyletic clade, and the previously suggested relationship between the Australasian species of the cosmopolitan genus Bertiella Stiles & Hassall, 1902 and species of Progamotaenia was supported. A low degree of phyletic co-evolution was detected within endemic Australasian clades. Colonisation rather than co-speciation appeared to be the principal means of diversification within the Australasian anoplocephaline radiation. The clade of bile duct-inhabiting Progamotaenia species emphasises the role of microhabitat rather than host species as a driver of speciation. Triplotaenia undosa Beveridge, 1976 described from a wide variety of macropodid hosts was found to be polyphyletic and a proposition was made to resurrect Wallabicestus Schmidt, 1975, with W. ewersi Schmidt, 1975 as the type-species and including W. ualabati (Beveridge, 2009) n. comb. [previously Progamotaenia ualabati Beveridge, 2009].
