Distribution and bionomics. This species is widely distributed in Antalya Province and is also known from Isparta Province ( Nabozhenko & Keskin 2016 ). It was previously collected on Juniperus oxycedrus L. in Isparta Province and on J. excelsa K. Koch in Antalya Province (Bey Dağları). In 2021 we collected O. inornata on Pinus brutia (Taşkesiği) , Quercus infectoria and on Pyrus sp. (Thermessos) ( Fig. 7A ). Beetles were active since 20:00 at the end of March. One of the host lichens (at least on Pyrus and Quercus ) is Physconia venusta (Ach.) Poelt. (Physciaceae) , but sometimes beetles can feed on Ramalina calicaris (L.) Fr. ( Parmeliaceae ) ( Fig. 6A ).
