Material examined.

East Kazakhstan Region: Putintsevo [ Путинцево] env. (49°52'N, 84°21'E), 472 m a.s.l., 21-24 VI 2017, 1♂, leg. WTS; 3♀♀, leg. LK; 1♂, leg. MW.


This species is currently known to be broadly distributed in Russia and in the Siberian part of Kazakhstan ( Danilevsky and Shapovalov 2007) as well as in Mongolia ( Hilszczański 2008). In Europe, it reaches Latvia ( Telnov 2016) and eastern Poland ( Hilszczański 2008). A. obscurior  was discussed in a previous paper concerning the longhorn beetles of Mongolia ( Karpiński et al. 2018).

Several specimens were beaten down from the branches and thin shoots of birches on an exposed site next to a river in a mountain deciduous forest dominated by Populus  and Salix  with an admixture of Betula  (Fig. 15D). In this region, the species is ecologically associated with birch, in contrast to its western boundary of occurrence (e.g. Poland), where all records are related to oak. We observed this species together with A. clavipes  , which was definitely more numerous and was mainly found on poplars and willows.
