Gaurotes virginea aemula (Mannerheim, 1852) Fig. 1A

Material examined.

Selenge Aimag : 40 km NE of Zuunkharaa, dark taiga (48°57'N, 107°05'E) (Fig. 6B ), 1270 m a.s.l., 04 VIII 2015, 1♀, on Chamaenerion angustifolium , leg. LK .

Remarks.

The species is distributed in the North Palaearctic region from Europe to Siberia, Sakhalin and the Korean peninsula ( Sama 2002), where it is divided into five subspecies ( Danilevsky 2017a). According to Danilevsky (2017), G. virginea aemula occurs from East Russia to the Far East, through Kazakhstan, northern Mongolia and China. It is probably polyphagous on coniferous trees. The larvae feed on dead stems, stumps and thicker branches. After two years, the larvae pupate in the soil ( Cherepanov 1990a).

In Mongolia, the species is also known from Töv Aimag. It was usually observed singly, e.g., 1 ex., 18 VI 1963; 1 ex., 23-24 VII 1965 ( Heyrovský 1964, 1967b). Only a single, still inactive female was found inside the calyx of Chamaenerion angustifolium in the morning, which may suggest that the species overnights in this plant.
