Bibio incrassatus
Heer, 1849: 221
.
Described from a single specimen from “k.k. montan. Cabinet” Vienna. The specimen was depicted by Heer (Pl.
XVI
Fig. 12
) but it is difficult to tell what it is. Heer’s figure may suggest the presence of a vein R
2+3
and a vertical crossvein R-M, in which case the species should be placed in the genus
Plecia
, possibly as a synonym of
Plecia
morio.
On the other hand, if this interpretation of the wing venation is incorrect, it may habitually resemble
Bibio
giganteus
.
Pongracz (1928: 183)
considered
Bibio morio
and
Bibio incrassatus
as probable synonyms.
