Material examined.

Toev Aimag : 75 km NE of Ulaanbaatar (48°10'N, 107°55'E), 1589 m a.s.l., 30 VII 2015 (22 II 2016, ex cult), 1♀, from Larix sibirica , leg. MW .

Remarks.

This oriental species is distributed widely from the Urals to Sakhalin and Japan ( Sama 2002, Danilevsky 2017a). It is ecologically associated with coniferous forests. The larvae develop in dead or drying trunks and twigs of various conifers, especially larches. After two years, the larvae pupate in wood during summer and the imagines emerge the next spring. The adults fly from May to August and, during the mating season, they stay on their host plants and occasionally visit flowers ( Švácha and Danilevsky 1988, Cherepanov 1990b).

In Mongolia, the species is also known, inter alia, from Khovd Aimag ( Heyrovský 1969).

One female was reared from a branch of a fallen larch Larix sibirica collected in the forest steppe (Fig. 7D ). The same material was inhabited by larvae of Monochamus impluviatus (Motschulsky, 1859) and M. sutor (Linnaeus, 1758).
