We revise the available material of fossil Bibionidae from the Oligocene of Germany, except for the Early Oligocene site of Kleinkems which has recently been revised. The bulk of the material originates from the Late Oligocene Lagerstätten of Rott and Enspel. One new species, Bibio castaneipennis sp.n., is described from Enspel. The following new combinations are established: Hesperinus heeri (Heyden Heyden, 1865) comb.n. (previously Plecia heeri), Plecia dubia (Germar, 1837) (previously Phthiria dubia). Plecia collossea (Heyden Heyden, 1865) is removed from synonymy with Plecia morio (Heer, 1849), Plecia gracilenta (Heyden Heyden, 1865) is removed from synonymy with Plecia lygaeoides (Heer, 1849). The following new synonymies are established: Plecia elegantula Meunier, 1915 = Penthetria rottensis Statz, 1943 = Penthetria scita Statz, 1943 = Hesperinus heeri (Heyden Heyden, 1865); Plecia superba Meunier, 1915 = Plecia imperialis Statz, 1943 = Plecia philippi Statz, 1943 = Plecia collossea (Heyden Heyden, 1865); Helophilus primarius Germar, 1837 = Plecia abava (Heyden Heyden, 1865) = Plecia satyrus Statz, 1943 = Plecia dubia (Germar, 1837); Plecia expositia (Heyden Heyden, 1865) = Plecia grandaeva (Heyden Heyden, 1865) = Plecia antenata (Heyden Heyden, 1865) = Plecia elongata (Heyden Heyden, 1865) = Plecia pulchella Meunier, 1915 = Plecia hypogaea (Heyden Heyden, 1865); Plecia schineri (Heyden Heyden, 1865) = Plecia macrocephala (Heyden Heyden, 1865); Plecia lapidaria (Heyden Heyden, 1865) = Bibio brachypteroides Meunier, 1915 = Plecia vulpina Statz, 1943 = Plecia pinguis (Heyden Heyden, 1865); Plecia lapidaria nigra Statz, 1943 = Plecia sluiteri Meunier, 1917; Plecia veterana (Heyden Heyden, 1865) = Plecia stygia (Heyden Heyden, 1865); Bibio spadicea Statz, 1943 = Bibio aerosus Statz, 1943; Bibio heydeni Meunier, 1920 = Bibio comosella Statz, 1943 = Bibio germari Meunier, 1920; Plecia heroica Heyden Heyden, 1865 = Bibio giganteus Unger, 1841; Bibio infumatus Meunier, 1915 = Bibio mimas L. Heyden, 1870. The following names are placed as nomina dubia pending rediscovery of the type material: Plecia volgeri (C.H.G. Heyden, 1859); Bibio janus L. Heyden, 1870; Bibio tertiarius C.H.G. Heyden, 1862; Dilophus deletus (C.H.G. Heyden, 1862). The male morphotypes described but not formally named by Statz (1943) are tentatively assigned to named species.
我们修订了德国始新世化石双翅目昆虫的现有材料，除了最近修订的早始新世克莱因克斯（Kleinkems）遗址外。大部分材料来自罗特（Rott）和恩斯佩尔（Enspel）的晚始新世化石产地。我们从恩斯佩尔（Enspel）描述了一个新种，即 Castaneipennis bibio 种。以下新组合成立：Hesperinus heeri (Heyden Heyden, 1865) comb.n.（以前为 Plecia heeri），Plecia dubia (Germar, 1837)（以前为 Phthiria dubia）。Plecia collossea (Heyden Heyden, 1865) 从 Plecia morio (Heer, 1849) 的同义词中删除，Plecia gracilenta (Heyden Heyden, 1865) 从 Plecia lygaeoides (Heer, 1849) 的同义词中删除。以下新的同义词成立：Plecia elegantula Meunier, 1915 = Penthetria rottensis Statz, 1943 = Penthetria scita Statz, 1943 = Hesperinus heeri (Heyden Heyden, 1865)；Plecia superba Meunier, 1915 = Plecia imperialis Statz, 1943 = Plecia philippi Statz, 1943 = Plecia collossea (Heyden Heyden, 1865)；Helophilus primarius Germar, 1837 = Plecia abava (Heyden Heyden, 1865) = Plecia satyrus Statz, 1943 = Plecia dubia (Germar, 1837)；Plecia expositia (Heyden Heyden, 1865) = Plecia grandaeva (Heyden Heyden, 1865) = Plecia antenata (Heyden Heyden, 1865) = Plecia elongata (Heyden Heyden, 1865) = Plecia pulchella Meunier, 1915 = Plecia hypogaea (Heyden Heyden, 1865)；Plecia schineri (Heyden Heyden, 1865) = Plecia macrocephala (Heyden Heyden, 1865)；Plecia lapidaria (Heyden Heyden, 1865) = Bibio brachypteroides Meunier, 1915 = Plecia vulpina Statz, 1943 = Plecia pinguis (Heyden Heyden, 1865) = Bibio heydeni Meunier, 1920 = Bibio germari Meunier, 1920；Plecia lapidaria nigra Statz, 1943 = Plecia sluiteri Meunier, 1917；Plecia veterana (Heyden Heyden, 1865) = Plecia stygia (Heyden Heyden, 1865)；Bibio spadicea Statz, 1943 = Bibio aerosus Statz, 1943；Bibio heydeni Meunier, 1920 = Bibio comosella Statz, 1943 = Bibio germari Meunier, 1920；Plecia heroica Heyden Heyden, 1865 = Bibio giganteus Unger, 1841；Bibio infumatus Meunier, 1915 = Bibio mimas L. Heyden, 1870。以下名称被列为可疑名称，等待重新发现模式标本：Plecia volgeri (C.H.G. Heyden, 1859)；Bibio janus L. Heyden, 1870；Bibio tertiarius C.H.G. Heyden, 1862；Dilophus deletus (C.H.G. Heyden, 1862)。施塔茨（Statz）（1943 年）描述但未正式命名的雄性形态类型被暂定为已命名物种。
