Remarks.

Anoplistes halodendri is an east-Palaearctic species that is distributed from the Balkans to the Russian Far East, China, Korea and Japan ( Danilevskaya et al. 2009). Within its range, it was divided into seven subspecies ( Danilevsky 2017a): A. h. balcanicus Sláma, 2010, A. h. ephippium (Steven & Dalman, 1817), A. h. halodendri (Pallas, 1773), A. h. heptapotamicus (Semenov, 1926), A. h. kasatkini Lazarev, 2014, A. h. minutus Hammarström, 1892 and A. h. pirus (Arakawa, 1932). The species is ecologically associated with deciduous trees and shrubs (e.g., Acacia , Daphne mezereum , Quercus ) in the steppe and forest-steppe habitats. Adults begin emerging in July ( Cherepanov 1990b).

The larvae (Fig. 8F, G ) collected in the first locality (Fig. 8H ) in stems of Caragana bungei (Fig. 9A ) clearly belong to the genus Anoplistes , but the exact species could not be identified with certainty. They are preliminarily classified in this taxon since it is the most common Anoplistes species in the country. Moreover, Anoplistes minutus is the only subspecies of A. halodendri that occurs in Mongolia. It was already recorded from this Province by Heyrovský (1969) and additionally from Khovd and Ömnögovi Aimags ( Heyrovský 1965, 1969). It is worth noting that one of the larvae among this material belongs to the tribe Clytini , most probably to the genus Chlorophorus .

Regarding the second locality (Fig. 9B ), several larvae were found together with the remains of a single male imago in stems of Caragana leucophloea . In both cases, the larval feeding grounds (Fig. 9C ) were located from a few centimetres below to approx. 10 cm above ground level. Most of the emergence holes (Fig. 9D ) of the adults were found on stems approx. a few centimetres above ground level. Both research plots are located in semi-desert habitats.

Apart from Anoplistes halodendri minutus , four other species of this genus were already recorded for Mongolia: A. gobiensis Namkhaidorzh, 1973, A. kozlovi Semenov & Znoiko, 1934, A. mongolicus mongolicus Ganglbauer, 1889 and A. tuvensis Tsherepanov, 1978 ( Danilevsky 2017a). Anoplistes tuvensis is distributed exclusively in the region of the Tuva basin and it is ecologically associated with Nanophyton erinaceum ( Cherepanov 1990b). Anoplistes kozlovi was recorded, inter alia, from Dundgovi, Ömnögovi and Govi-Altai Aimags ( Heyrovský 1965, 1968) and A. mongolicus from Khovd, Govi-Altai, Ömnögovi, Bayankhongor and Dundgovi Aimags ( Heyrovský 1968, 1970). However, taxonomy, distribution (especially in the Mongolia and China region) and biology of most of the species in this genus need to be thoroughly studied and revised.
