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.
