Distribution. Euro–Siberian, boreal. Northern European regions,?central European regions, Middle and S Urals, southern part of Krasnoyarsky Kray, Khakassia, Altai, Irkutskaya Oblast, Republic of Buryatia, S Yakutia. Outside Russia in N Europe (Scandinavia), NW China.

Hostplants: Polygonum , Rumex ( Hausmann 2004) , Trifolium , Atriplex , Prunus ( Mironov 1999) .

Remarks. The griseata species group includes, apparently, four species, which inhabit Siberia: T. griseata , T. recompta (Prout, 1930) , T. comae Schmidt, 1931 and T. paralias (Prout, 1935) . Only the last one definitely differs in morphology, whereas the former three species are difficult to distinguish in appearance and genitalia structure as well. Nevertheless, it was shown that apart from the slight morphological differences ( Kaila & Albrecht 1994; Hausmann 2004; Vasilenko 2008; Cui et al. 2019), T. griseata and T. comae are differentiated in COI ( Õunap et al. 2005).
