According to Borkent's revision, only three species of
Stenochironomus are known from Europe:
S. hibernicus with pale wings,
S. gibbus with a median band and small apical band, and
S. fascipennis with a median band and large apical dark band (entering cells r3 and cua1).
The genus is much more speciose in Japan and the Americas.
