Anaesthetis confossicollis Baeckmann, 1903

Literature data. Sükhbaatar: 12 km SW of Dariganga [Дарьганг], Moltsog-Els [ур. Молцог-Элс] [ca. 45.437, 114.139], 17.07.1976, 1 ex. (Namhaidorzh 1979) .

Remarks. This species is distributed in the Ussuri-Primor’e region, Mongolia, northeast China, the Korean peninsula, and Japan (Cherepanov 1991a; Danilevsky 2020).

According to Cherepanov (1991a), A. confossicollis inhabits broad-leaved forests and it is ecologically associated with Quercus, however, it seems more likely that larvae of this species can also feed on other deciduous woody and shrub species, similar to its close relative, Anaesthetis testacea (Fabricius, 1781), which, however, can easily be distinguished by the more uniform fine punctation and very dense pronotal pubescence.

Imagines emerge from mid-June to the second half of July. This species was found in large numbers in fire-ravaged forest (Cherepanov 1991a).
