Material examined.

Selenge Aimag : 50 km NE of Zuunkharaa (49°05'N, 107°17'E), 930 m a.s.l., 02 VIII 2015, 1♀, leg. MW .

Remarks.

The species is distributed in northern Asia eastwards from about Baikal Lake to the Pacific Ocean. According to Danilevsky (2014a), all records for Altay and Tuva were connected with misidentifications of Pachytodes bottcheri (Pic, 1911). The southern edge of its occurrence reaches the forest areas of northern Mongolia, China, and Korea ( Cherepanov 1990a, Danilevsky 2017a). Pachytodes longipes is probably a polyphagous species, which usually inhabits the basal zones of deciduous wood species. The larvae develop in rotten wood around and in roots. Adults were found from July to August. The species is characterised by the highly variable colour of the elytra ( Cherepanov 1990a).

The species was recorded in Mongolia by Lobanov et al. (1981), but with no specific locality data ( Danilevsky 2017b). It is well known from Töv and Arkhangai Aimags ( Danilevsky 2014a). Recently, one specimen of this species was also collected by Müller et al. (2013) in the West Khentey region.

A single specimen was caught flying in the light taiga habitat next to a river (Fig. 6F ). Our finding confirms its presence in this region.
