Idiocnemis patriciae from southern Papua New Guinea
Idiocnemis patriciae sp. is described from lowland rainforests of the Dark-End Lumber and Lakekamu regions in Gulf Province, Papua New Guinea. Biogeographically, the new species is
near-endemic to the Papuan Gulf Coastal Lowlands area of endemism. Notes on the habitat of the new species and on a female specimen from the Lakekamu Basin tentatively assigned to it are included. The distributions of I. australis Gassmann, I. chloropleura Lieftinck and I. kimminsi Lieftinck are updated. I. chloropleura is recorded from Yapen island for the first time. A revised
key to the males of the Idiocnemis inornata species-group is provided.
