New records of Liorhyssus hyalinus (Fabricius, 1794) (Hemiptera: Heteroptera: Rhopalidae) from the northeastern Komi Republic, Russia

The article reports on a new finding of Liorhyssus hyalinus (F.) in the Komi Republic. In 1970–1974, the species was documented only in the middle taiga (63°33ʹ22ʺ N, 53°39ʹ56ʺ E). In 2022, it was discovered at a new location in the southern forest tundra (66°27ʹ54ʺ N, 60°43ʹ10ʺ E), over 460 km to the north of the previous finding. This is the northernmost known occurrence of Liorhyssus hyalinus (F.) globally, significantly extending the northern boundary of its range. The article also synthesizes existing literature on the biology, phenology, feeding habits, and distribution of this species, both within Russia and beyond.
