Remarks. Gyrophaena pseudonitidula was originally described from Far Eastern Russia (“ Primorski Krai, Suputinsky Reserve…”), Krasnoyarsk Territory, Khanty-Mansi Autonomous region, Udmurtia and Chuvashia. Glotov (2022) recorded it from the Maritime Province (“S Artyom town env., 100–300 m, Ozernyi Kluytch Riv…”). For illustration of the species see Figs 2–3 in Semenov et al. (2015).
