Remarks. The Holarctic Omalium oxyacanthae ( Fig. 3 ) was recorded from Irkutsk ( Shavrin et al. 1999), Chita ( Shavrin 2010) and Magadan ( Ryabukhin 1999, 2002) areas, and Kamchatka Territory ( Ryabukhin 1999, 2010, 2020, 2024). Eppelsheim (1893) recorded it from Irkut valley, but all studied specimens from NMW identified as “oxyacanthae ” refers to O. subsolanum (see below).

It is here recorded from Amur Area for the first time.
