Material examined.

Selenge Aimag : 50 km NE of Zuunkharaa (49°05'N, 107°17'E), 930 m a.s.l., 02 VIII 2015, 2♂♂, leg. MW .

Remarks.

Agapanthia pilicornis pilicornis is distributed in the Ussuri-Primor’e region, Trans-Baikal, Sakhalin, northern Mongolia, northeast China, Korean peninsula, and Japan ( Cherepanov 1991a). The second subspecies, A. pilicornis laushanensis Breuning, 1965, is known exclusively from two Chinese provinces: Henan and Shāndōng ( Danilevsky 2017a). Little is known about the biology of this species. The imagines are active in June and July, but the life cycle and the preimaginal stages are not clearly understood ( Cherepanov 1991a). This species is quite similar to Agapanthia amurensis Kraatz, 1879; however, it can be easily distinguished inter alia by variegated antennae and darker body colour.

This is a rather infrequent taxon in Mongolia and is absent in most of the papers about this region (e.g., Heyrovský 1964 - 1975). The only records of approx. ten specimens, collected from the second half of June to mid-July, are included in the work of Namhaidorzh (1972).

Our finding extends the known period of occurrence of this species to the beginning of August. Two males were collected in the light taiga habitat (Fig. 7C ) by sweep-netting method.
