Type host plant. Hypericum lydium Boiss. (Hypericaceae). Relation to host plant. The mites were vagrant on leaves. Type locality. Geva in Van, Turkey (3817'52"N, 4306'43"E), altitude 1044 m above sea level, coll. E.

Type material. Holotype female [4018(1)] and 7 female paratypes: [4011, 4013, 4017, 4018(2), 4019(1), 4019(2) & 4023] deposited in the collection of the Faculty of Biology, Adam Mickiewicz University, Poznań, Poland and 4 female paratypes [4020–4022(1–2)] deposited in the collection of the Department of Applied Entomology, Faculty of Horticulture, Biotechnology and Landscape Architecture, Warsaw University of Life Sciences—SGGW, Warsaw, Poland.
Etymology. The new species name (adjective in the genitive case, masculine) is derived from the specific name of its host plant.
Differential diagnosis. Aculus lydii n. sp. can be differentiated from a closely-related species, Aculus hyperici (Liro, 1943) on Hypericum perforatum L., which was first described from Finland by: its body length (155–170 in A. hyperici; 200–268 in A. lydii n. sp.), the number of opisthosomal annuli (38–40 in A. hyperici compared with 49–54 dorsal and 59–63 ventral in A. lydii sp. n.) and the ornamentation of the prodorsal shield (smooth in A. hyperci; ornamented in A. lydii n. sp.). Both species are leaf vagrants.
