Peltigera macra and P. tereziana var. philippinensis are reduced to synonymy with P. nana, whereas P. melanocoma is maintained as a species distinct from P. nana pending further studies. The status of several putative taxa referred to P. dolichorhiza s. lat. in the Sect. Polydactylon remains to be studied on a wider geographical scale and in the context of P. dolichorhiza and P. neopolydactyla. The phylogenetic affinities of all but one regional species (P. extenuata) are studied based on inferences from ITS (nrDNA) sequence data, in the context of a broad taxonomic sampling within the genus. A key to all species is provided and available data on their ecology and general distribution are discussed. The species P. canina, P. horizontalis, P. laciniata, P. malacea, P. polydactylon and P. tomentosa are excluded from the lichen checklist of Papua New Guinea. All lichenicolous fungi observed on Peltigera thalli in Papua New Guinea are listed.} }
