z2 22 (18–23), z4 22 (18–23), Z4 67 (63–75), Z5 147 (135–155), s4 55 (50–60), r3 18 (15–20),

R 1 16 (13–18).

World distribution — Ukraine ( Demite et al. 2022) and Romania (this study).

Hosts / Substrates — Soil and litter at the roots of oak ( Quercus spp. - Fagaceae ), as well as from sand and gravel from interstitial zone on sea-beach of Crimea ( Kolodochka 2003 ; Demite et al. 2022).

Remarks — Our findings recommend this species as being a preferential praticolous one, in DDBR being found only in meadows, never in the samples from forests. Amblyseius terreus was described from Crimea and until now no other reports of this species are available. Therefore, this new record is also significant from zoogeographical point of view. With 70 specimens in total, in four stands, this species was one of the most abundant species within this survey. Morphological characters are very close to the original description.
