East Kazakhstan Region: Putintsevo [ Putintsevo ] 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. Remarks. 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 ( Hilszczanski 2008 ). In Europe, it reaches Latvia ( Telnov 2016 ) and eastern Poland ( Hilszczanski 2008 ). A. obscurior was discussed in a previous paper concerning the longhorn beetles of Mongolia ( Karpinski 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.
