Cestode parasites of tree kangaroos (Dendrolagus spp.: Marsupialia), with the description of two new species of Progamotaenia (Cestoda: Anoplocephalidae)

Abstract

Two new species of Progamotaenia Nybelin, 1917 are described from tree kangaroos: P. dendrolagi sp. n. from the small intestines of Dendrolagus bennettianus De Vis, 1887 and D. lumholtzi Collett, 1884 from northeastern Queensland, and P. irianensis sp. n. from the intestine of D. dorianus Ramsay, 1883 from Irian Jaya. A re-description of P. wallabiae Beveridge, 1985, from D. dorianus, a new host for the genus, is given. P. dendrolagi is highly host specific, being restricted to tree kangaroos, while P. wallabiae occurs also in scrub wallabies of the genus Dorcopsis Schlegel & Mueller, 1842 from the island of New Guinea. The phylogenetic relationships of P. irianensis with congeners are not c..
