synonyms

Chlorops cingulata Meigen, 1830.

note

Galls of this type generally are referred to Chlorops pumilionis, but in fact a number of species are involved, that can only be identified on the basis of reared material. C. strigulus is characterised by the large frontal triangle, far drawn out anteriorly and with deep grooves at either side, and by the white arista (JY Baugnée).
