Franco ( Cupressaceae ), ornamental plantings, ( 45°01ʹ04ʺN 38°57ʹ06ʺE ), Krasnodar , Krasnodar Krai , Russia , 25-VI-2022 . Three females collected on Thuja occidentalis L. ( Cupressaceae ), ornamental plantings, ( 45°03ʹ25ʺN 38°54ʹ55ʺE ), Krasnodar , Krasnodar Krai , Russia , 26-IV- 2018. Three females , 1 nymph collected on P. orientalis and T. occidentalis ( Cupressaceae ), ornamental plantings, ( 44°43ʹ13ʺN , 37°46ʹ34ʺE ), Novorossiysk, Krasnodar Krai , Russia , 3-5-X-2018 . Host plants — This species has previously been recorded on Cupressaceae , Pinaceae , Tamaricaceae , Celastraceae ( Migeon and Dorkeld, 2023 ) . Eotetranychus libocedri is recorded for the first time on P. orientalis ( Cupressaceae ). Remarks — To complete the record, dorsal aspect and shape of the first three pairs of dorsocentral setae c ( 1 , d1 and e1 ) of E. libocedri female are illustrated in Figures 1 A-B. Male aedeagus is shown in Figure 1C . Most of all known records of E. libocedri in Eurasia are associated with ornamental plants both in our study and according to literature data ( Yeşilayer and Çobanoğlu, 2015 ; Kontschan, 2019 ). Based on these considerations and taking into account the wide application of Cypress plants for ornamental purposes, it is assumed that the actual distribution of E. libocedri in Eurasia may be much larger than known by present time.
