Systematic study of the genus Phorinia Robineau-Desvoidy of the Palearctic, Oriental and Oceanian regions (Diptera:Tachinidae)
The exoristine genus Phorinia Robineau-Desvoidy of the Palearctic, Oriental and Oceanian regions is revised. Sixteen species are recognised, fifteen of them described as new. Phylogenetic relationships of Phorinia are analysed using morphological characters. The analysis reveals that Phorinia is clearly monophyletic and closely related to Ctenophorinia Mesnil within the tribe Exoristini. The following three species-groups are defined in this genus: the aurifrons-group: Phorinia aurifrons Robineau-Desvoidy; P. breviata, sp. nov.; P. minuta, sp. nov.; P. aduncata, sp. nov. and P. convexa, sp. nov.; the bifurcata-group: P. bifurcata, sp. nov.; P. quadrata, sp. nov.; P. longiseta, sp. nov. and P. spinulosa, sp. nov.; and the flava-group: P. flava, sp. nov.; P. gracilis, sp. nov.; P. australiana, sp. nov.; P. denticulata, sp. nov.; P. insignita, sp. nov.; P. occidentalis, sp. nov. and P. orientalis, sp. nov.
