New species of damselflies from the Hindenburg Wall region of western Papua New Guinea (Odonata: Coenagrionidae, Platycnemididae)

Two new species of Teinobasis and one new species of Nososticta from the Hindenburg Wall region of western Papua New Guinea are described and illustrated. They are Teinobasis cuneata sp. nov. (Holotype SAMA 07-001421), Teinobasis flavolineata sp. nov. (Holotype SAMA07-001422), and Nososticta oculata sp. nov. (Holotype SAMA 07-001424). The new Teinobasis species are both moderately large, slender species with predominantly yellow/orange faces and black abdomens and they are most similar to T angusticlavia Ris from the Aru Islands and T albula Ris from the Lorentz River. The new Nososticta species is most similar to N. finisterrae Forster, a species that is widespread in south-eastern New Guinea, but differs from it in having the blue inter-ocular bar that is typical of finisterrae reduced to two widely separated pale blue spots on the anterior frons.
