Localities: Rott

Type: Coll. Krantz, Bonn (not seen)

Transferred to Dilophus by L. Heyden, 1870

Total length 7.7 mm

The type is, according to C.H.G. Heyden (1859, 14 and Plate II, Fig. 13) a poorly preserved male with wings missing. L. Heyden (1870) transferred the species to Dilophus but did not further describe it except by noting it was smaller than Dilophus krantzii . We have not been able to find the type specimen, judging from the original description it is probably not recognizable even to genus level, and should be treated as a nomen dubium.
