Abstract: Homorosoma asperum (Roelofs, 1875) ** (Fig. 7) Material: 13: Turachak riv., alt. 450 m, 10-14.VII.2019, leg. A & VL – 1 ex. Remarks. This species was known from the Russian Far East, Korea, Japan and China (Legalov 2020c, Alonso-Zarazaga et al. 2023) (Fig. 8). A female of Homorosoma asperum was collected from NE Altai (Fig. 7). This is the first record of this species from Siberia and the northernmost find of this specie. Two specimens of H. asperum were collected from Kazakhstan (East Kazakhstan Region, Kurshim District, 12 km S of Boran, Cherny Irtysh River, 14.VI.1997, R. Dudko & V. Zinchenko) (Fig. 8). This is the first record of this species from Kazakhstan and the westernmost find of this species. Homorosoma asperum is similar to H. aterrimum (Hustache, 1916) but differs in larger body size, broader and shorter rostrum, broader antennal club, and broader aedeagus slightly narrowed to the apex (Fig. 7). Homorosoma aterrimum is recorded for Primorskii Krai (Legalov 2020c), but is not listed for Russia (Alonso-Zarazaga et al. 2023). Three specimens are known from the south of Primorskii Krai (1 ex., Khasansky Distr., Vitjaz’, 25.VII.-2.VIII.2000, S.A. Krivets; 2 ex., Lazovsky Distr., env. Lazo, 6- 10.VI.2008, V. Shorhrin).
