A species, previously known from a short description based on the holotype lost in the bombing of Hamburg before description, T. kogardtauica Hering, 1944, was collected recently in great numbers in the Middle East, from Iran to Kyrgyzstan; it is redescribed, and the neotype is designated. The flies were found to infest flower heads of Inula stenocalathia (Rech. f.) Soldano, I. peacockiana (Aitch. & Hemsl.) Korovin, and I. grandis Schrenk ex Fisch. & C. A. Mey.
