Material: NSY, Gildeskål: Forstranda , 66.997170°N 13.885166°E ± 4m, 19 July 2022, LMF, leg. HE GoogleMaps , coll. NHMO; Sund, Sundsfjellet , 67.066157°N 14.059922°E ± 5m, 21 July 2022, LMF, leg. HE GoogleMaps , coll. NHMO.

Biology and notes: The white to orange larvae develop in galled leaflets of Vicia sylvatica ( Fabaceae ). Infected leaflets are folded up over the midrib and hardened to form a pod-like gall. Bi- or multivoltine. Pupation and hibernation in the soil. In the sample from Sundsfjellet, we also found white larvae of Macrolabis sp. living together with Tricholaba viciobia . This species is mentioned in Roskam (2019) but is apparently undescribed.

Distribution: Only known from Germany, Czech Republic and Norway.
