Material examined. Crimea: Bakhchysarai District, between Vysoke and Sokolyne vill., 44.59409°N 33.94985°E, 25– 27.04.2009, 1 ♀ (Khodakivska); Bakhchysarai District, Besh-Kosh Mt. , 44.749444°N, 33.925556°E, 01.05.2010, 2 ♀ (Kizub) .

Distribution. Ukriane: the Crimea, Donetsk, Kharkiv, and Luhansk Regions ( Nazarenko & Sheshurak, 2003; Yunakov et al., 2018 a, b). Moldova ( Poiras, 2006), central and southern European part of Russia ( Reitter, 1888; Isaev, 1998; Ismailova, 2007; Korotyaev, 2007; Korotyaev & Arzanov, 2010; Arzanovm 2012; Mukhtarova, 2012; Yunakov et al., 2012; Korotyaev & Zabaluev, 2014; Arzanov, 2015; Mukhtarova & Abdurakhmanov, 2015; Krasnobaev, 2017; Brekhov, 2018), Ukraine ( Nazarenko & Sheshurak, 2003; Yunakov, 2003 b; Yunakov et al., 2018 a, b), Azerbaijan ( Alonso-Zarazaga et al., 2017), and Georgia ( Cholokava, 1996, 2008; Gogoberidze, 2006).

Biology. Mesophilic, nocturnal species inhabiting deciduous and mixed forests ( Yunakov, 2003 b; Yunakov et al., 2018 a). The species is a dendrobiotic and polyphagous, feeds on Acer tataricum , Carpinus sp. , Crataegus sp. , Fagus sp. , Malus pumila , Quercus sp. , Pyrus eleagrifolia , Rosa sp. , Sambucus nigra , and Ulmus sp. ( Yunakov, 2003 b; Poiras, 2006; Yunakov et al., 2018 a). The species could damage Acca sellowiana , Citrus limon , C. reticulata , C. sinensis , Laurus nobilis , M. pumila , Prunus persica , Pyrus communis , Ribes rubrum , Rosa sp. , Rubus sp. , and other plants in Georgia ( Cholokava, 1996), and grapes in Eastern Caucasus ( Abdullagatova, 2009). Ukrainian populations of the species are parthenogenetic whereas the bisexual form is represented in Western Caucasus ( Yunakov, 2003 b; Yunakov et al., 2018 a). It may suggest that the species originates from this region.

Taxonomic notes. Some researchers suggest that O. pilosus should be excluded from the subgenus Choilisanus ( Davidian & Keskin, 2010; Davidian & Gültekin, 2015). Except for the nominative subspecies, O. pilosus samsunensis Smreczynski, 1977 has been described from Turkey ( Alonso-Zarazaga et al., 2017).
