Tasmanian Phoridae (Diptera) and some additional Australasian species

The list of Phoridae recorded from Tasmania is increased from five species in three genera to at least 52 species in eight genera. One species on the original list is transferred to the status of being incertae sedis. One new genus and 37 new species are described, two being reported from mainland Australia also. One species was previously only known from New Zealand, five from mainland Australia, four from Europe but one of which is now an almost cosmopolitan tramp species and one being from the Holarctic Region. However, one of the 'European' species may have orginally been introduced to Europe from Tasmania. Keys to genera, to all known species of Aphiura, to the Tasmanian species of Megaselia and to the Australasian species of Metopina are provided. A newly named and a new mainland Australian species of Aphiura, three mainland Australasian species of Metopina and three from Papua New Guinea are described and seven undescribed males (given code letters only) of this genus are included in the key (four from Papua New Guinea, two from Western Australia and one from Tonga). Aphiura and Paraphiura are transferred to the tribe Metopinini and the tribe Beckerinini is set aside, as it cannot be satisfactorily characterized as it is currently conceived. Megaselia dissita is synonymized with M. comparabilis.
