Comments. Acanthomegabunus sibiricus is the only species previously known from the Katunsky Biosphere Reserve. The species was recorded from the vicinity of Srednee Multinskoe Lake (erroneously named Srednee Kuktinskoe Lake) ( Tchemeris 2015). The lake is actually located outside the reserve, close to its northern border where the reserve’s ranger station is situated, although this record requires confirmation because it is based on a single female. A closely related species, A. altaicus Tchemeris, 2015 , may also occur there—its type locality lies close to the Katunsky Reserve (East Kazakhstan Area, Katon-Karagaiskii Districts).

Habitat. Mountain moss-stony tundra, moss-pebble riverbanks, Abies forest, Anemone meadows, stony debris, dark coniferous forests, and aspen-fir forests ( Tsurusaki et al. 2000b; Trilikauskas 2016, 2017).

Distribution. The mountains of South Siberia, Russia: the southern part of Krasnoyarsk Territory, Altai Territory, and Altai Republic, Kemerovo Area, Khakassia, and Tuva ( Tchemeris 2015).
