Material examined. AKERSHUS: Frogn, Danmark, 59.694978°N, 10.722395°E, 17.V-21.VII.2004, 1♂, E. Rindahl & L. Aarvik leg. TELEMARK: Hjartdal, Teleros, 59.595696°N, 8.617237°E, 2.VII.2017, 1♀, leg. G.Kvifte. SOGN OG FJORDANE: Luster, Ulveskogen, 61.447095°N, 7.46586°E, 24.VI.2017, 1♀, leg. G.Kvifte.

Remarks. A rare species, listed as vulnerable (VU) on the most recent Norwegian red-list. Of the new records presented here, two were associated with old-growth Ulmus trees which may provide clues for further searches for the species. All known Trichomyia larvae develop in rotting wood and many species particularly in Europe seem restricted to old-growth forests (e.g. Withers 1989, Beran et al. 2010, Omelková & Ježek 2012 a, Morelli 2018).
