Bibio ungeri Heer, 1849: 218 . ( Figs. 18 , 38 )

Bibio lignarius Germar, 1837 sensu Unger, 1842 , pro parte

This species is not a bibionid, the type (SLJG, no catalogue number) is a brachyceran, possibly Xylophagidae . This was commented on already by Heer (1849: 218) who nevertheless placed the species in genus Bibio based on the wing venation. This is not at all clear in the holotype but there appears to be closed discal and anal cells in the wing. From the specimen label it is clear that Unger did not intend to describe the specimen as a new species, but (mis)identified it as Bibio lignarius Germar. Both head and legs are missing in the type specimen, and the wing venation is very difficult to interpret, so this species is likely to remain a nomen dubium.
