Revision of fossil Bibionidae (Insecta: Diptera) from French Oligocene deposits Author Skartveit, John Author Nel, André text Zootaxa 2017 4225 1 1 83 journal article 37263 10.5281/zenodo.259087 05be601b-f9f1-4952-ac09-7012ef31aab0 1175-5326 259087 4676EE59-569B-4197-B108-9B32FD88E68E Bibio moestus Heer, 1849 This species was described from Öhningen, Southern Germany and redescribed by Skartveit & Pika (2014) . It was recorded from Aix-en-Provence by Heer (1856: 33 – 34) , one specimen is in ETHZ ( Skartveit & Pika 2014 ). Since Heer did not illustrate the specimen from Aix-en-Provence it is uncertain if the specimen in ETHZ is the one recorded by Heer, though the specimen is labelled in Heer’s handwriting. The Aix specimen in ETHZ labeled as B. moestus is most likely not conspecific with the specimens from Öhningen which form the type series ( Skartveit & Pika 2014 ), but is probably a female of Bibio curtisii . The presence of B. moestus in French Oligocene sites is thus unproven, and we regard it as unlikely.
