A 19th century New Ireland dog, Canis familiaris novaehiberniae Lesson, 1827 and the status of Canis hallstromi Troughton, 1957
Recent literature has usually invoked the name Canis hallstromi Troughton, 1957, though with varied taxonomic interpretations, when writing of dogs thought to be unique to New Guinea. The name Canis familiaris novaehiberniae was proposed for dogs from the New Guinea region 130 years before Troughton published Canis hallstromi but has been overlooked in the recent literature, as has Canis familiaris papuensis Ramsay, 1879 from southeastern New Guinea. The taxonomic status of New Guinea dogs remains controversial but if dogs from New Guinea and New Ireland represent a single heterogeneous gene pool, then C. hallstromi Troughton and C. familiaris papuensis Ramsay would be junior subjective synonyms of C. familiaris novaehiberniae Lesson, 1827. Recent studies of New Guinea dogs are weakened by their failure to attend carefully to the history of discovery and nomenclature of these animals.
