New species of Peromyia from Tasmania, with a revision of Schiner's and Skuse's types of Australian Micromyinae (Diptera: Cecidomyiidae).

Abstract

Peromyia Kieffer, 1894, a speciose, cosmopolitan genus of micromyine cecidomyiids, is shown to occur in Tasmania. This is the first record of the genus in Australia and the first contribution to the taxonomy of Australian Micromyinae for 120 years. Nine of the 12 species found proved to be new to science: Peromyia grovei sp. n., P. nitoda sp. n., P. indecorata sp. n., P. warraensis sp. n., P. bashfordi sp. n., P. despecta sp. n., P. debilis sp. n., P. cinalata sp. n., and P. tasmanica sp. n. Four of the new species are assigned to the Peromyia dissona group, which is established for a chiefly western Pacific species radiation. Other Tasmanian peromyias are assigned to species groups that to present knowledge are widely distributed accross the Holarctic Region and occasionally beyond. The types of the Micromyinae species from Australia by Ignaz R. Schiner and Frederick A. A. Skuse are revised. None of the 11 species belongs to the genus Campylomyza Meigen, 1818, where they were originally assigned. Campylomyza grandiuscula Skuse, 1890 is actually a species of the genus Pteridomyia Jaschhof, 2003. The remaining species either belong to the genus Peromyia or their generic affiliation could not be determined. Peromyia aeratipennis (Skuse, 1888) comb. n. takes priority over Peromyia muscorum (Kieffer, 1895) syn. n., and Peromyia impexa (Skuse, 1888) comb. n. takes priority over Peromyia palustris (Kieffer, 1895) syn. n. Peromyia pellax (Skuse, 1888) comb. n., syn. n. and Peromyia subtilis (Skuse, 1888) comb. n., syn. n. are identical with Peromyia impexa. Campylomyza sidneyensis Schiner, 1868, Campylomyza amplipennis Skuse, 1888, Campylomyza crocea Skuse, 1888, Campylomyza perpallida Skuse, 1888, Campylomyza persimilis Skuse, 1888, and Campylomyza vicina Skuse, 1888 are relegated to nomina dubia.
