Macropodines from the Pliocene Otibanda Formation, Papua New Guinea

Abstract
Newly collected material of macropodines from the Otibanda Formation, P.N.G., includes previously unknown elements from described taxa, as well as material of a new and plesiomorphic macropodine, Watutia novaeguineae gen. et. sp. nov. Known only from adult upper and lower cheek tooth rows, this species shows a close similarity to undescribed macropodines of Tertiary age from northwestern Queensland and Hadronomas puckridgi from the Miocene of the Northern Territory, Australia. The upper molar row assigned to Dorcopsis sp. by Plane (1967), but regarded to be more closely related to Dendrolagus by Woodburne (1967), is here interpreted to be closer in morphology to species of Dorcopsis than Dendrolagus.
