A revision of the Patagonian predaceous midges of the genus Palpomyia Meigen (Diptera: Ceratopogonidae).

This revision of the predaceous midges in the genus Palpomyia Meigen inhabiting the Patagonian region of Argentina and Chile recognizes eight species, provides diagnoses, descriptions, illustrations and a key to all species, as well as new distributional records of previously described species. Four new species are described and illustrated: P . mapuche , P . marinoi , P . septentrionalis and P . yamana (spp. n.). Palpomyia patagonica Ingram and Macfie and P . subfuscula I. and M. are redescribed and illustrated, the previously unknown male of P . patagonica is described and illustrated, and P . subaspera (Coquillett) is recorded for the first time from Patagonia. Palpomyia chilensis Ingram & Macfie is transferred to Austrosphaeromias Spinelli (n. comb.).
