Macropostrongyloides dendrolagi n. sp. and Mbaisonema coronatum n. g., n. sp, two new species of nematodes (Strongyloidea: Cloacinidae) from tree-kangaroos, dendrolagus spp. (Marsupialia: Macropodidae) from Irian Jaya, Indonesia

Abstract

Two new species of strongyloid nematodes are described from tree-kangaroos, Dendrolagus spp. (Marsupialia: Macropodidae), from Irian Jaya, Indonesia. Macropostrongyloides dendrolagi n. sp. from the colon of Dendrolagus dorianus (type-host) and D. mbaiso is distinguished from congeners by the presence of a cephalic inflation and paired lateral alae which extend along the body from the cephalic inflation. Mbaisonema coronatum n. g., n. sp., from the stomach of D. mbaiso, is allocated to the tribe Coronostrongylinea Beveridge, 1986, as the buccal Capsule is reduced to a sclerotised annulus and the lining is inflated into lip-like lobes at the anterior extremity. The new genus is allied to Popov..
