Reviewed status of the Afrotropical signal fly genera Federleyella and Conopariella and a new genus (Diptera, Platystomatidae, Plastotephritinae)

A collection of Plastotephritinae specimens by the late Amnon Freidberg, which were collected in 2010, included long series of species for which only a few specimens were previously known. These long series shed new light on the genera Federleyella Frey, 1932 and Conopariella Enderlein, 1922 in particular. The status of these two genera is reviewed. Federleyella is considered a junior synonymy of Conopariella. As a consequence, the combination Conopariella pallidipes (Enderlein, 1922) is reinstated. Anaphalantias septemfenestrata Enderlein, 1922, previously in Federleyella, is placed in synonymy with Conopariella pallidipes (n. syn.). A revised key to genera of Plastotephritinae is provided and Conopariella is redescribed and a key provided for the species assigned to it. Each species is provided a differential diagnosis comprising distinguishing features and new records and/or distribution extensions are commented upon. A new genus, Meniscomyia (n. gen.) and species, Meniscomyia phaia (n. sp.), distinctive within the Plastotephritinae, are described, despite having just a single specimen.
