Abstract

Abstract Pyrgotid Flies assigned to Apyrgota. I. New Species and Synonyms in Eupyrgota (s. str.) (Diptera, Pyrgotidae), with Description of a New Subgenus. Korneyev, V. A. - Eupyrgota scioida Hendel, 1908, the type species of the genus Apyrgota Hendel, 1909, syn. n. is shown to belong in Eupyrgota Coquillett, 1899. Th e diagnoses of the genus Eupyrgota and the subgenus Eupyrgota (s. str.) are reconsidered. E. alienata (Walker, 1861) comb. n., E. brahma (Hendel, 1914), comb. n., E. aequalis (Malloch, 1939), comb. n., E. angustifrons (Bezzi, 1914), comb. n., and E. armipes (Hendel, 1914), comb. n. are transferred into Eupyrgota (s. str.). Th e following synonymy is established: Eupyrgota Coquillett, 1899 = Apyrgota Hendel, 1909, syn. n.; E. alienata (Walker, 1861) = E. scioida Hendel, 1908, syn. n.; and E. brahma (Hendel, 1914) = Adapsilia nocturna Bezzi, 1914, syn. n. E. nyambene V. Korneyev, sp. n. is described based on a single female from Kenya; the new species belongs in the varipennis subgroup, but diff ers from other species by having a slender fore femur (thickened in E. varipennis Curran) and the mid femur with a femoral organ (absent in E. rugosigenis Hendel). A monotypic subgenus Asipyrgota subgen. n. (type species: Adapsilia flaviseta Malloch, 1929) is established; it shares the presence of the nipple-like processes of the prosternum, a generally robust appearance, and presence of 3 pairs of scutellar setae with members of the subgenus Eupyrgota s. str., diff ering by the absence of paired ventro-apical hooks on the oviscape.
