Abstract

Eupyrgota scioida Hendel, 1908, the type species of the genus Apyrgota Hendel, 1909, syn. n. is shown to belong in Eupyrgota Coquillett, 1899. The 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.). The 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 differs 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 fl aviseta 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., differing by the absence of paired ventro-apical hooks on the oviscape.
