Coxal plates with dashes; suboral plate with dots. Setae 1 b 12 (12–18), 10 (10–12) apart; setae 1a 21 (20–30), 7 (6– 7) apart; setae 2a 37 (32–37), 21 (20–27) apart; sternum 8 (5–9). Opisthosoma with 58 (47–62) annuli with triangular pointed microtubercles; dorsal microtubercles larger, ventral tiny; microtubercles elongated on the posterior 2 (1–3) annuli. Setae c 2 36 (36–40), on 3 rd (2 nd to 4 th) annulus; setae d 50 (42–56), on 15 th (14 th to 18 th) annulus; setae e 23 (19–24), on 26 th (26 th to 34 th) annulus; setae f 32 (24–34), on 54 th (45 th to 56 th) annulus, 6 th (6 th) annulus from rear. Setae h 1 4 (4–5); setae h 2 43 (36–44). External genitalia 20 (20–25), 23 (23– 26) wide, genital coverflap with 6 (6–8) striae; setae 3a 20 (17–22), 20 (18–21) apart.

Male, nymph and larva. Not found.

Type host plant. Onosma isauricum Boiss. et Heldr.  ( Boraginaceae  ).

Relation to host plant. The mites were vagrant on leaves.

Type locality. Gevaş in Van, Turkey (38 ° 17 ' 52 "N, 43 °06' 16 "E), 1040 m above sea level, coll. E. Denizhan, 16 June 2008.

Type material. Holotype female [3961 (1)] and 6 female paratypes [3953–3958] deposited in the collection of the Faculty of Biology, Adam Mickiewicz University, Poznań, Poland and 3 female paratypes [3963–3965] 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 specific mite name (adjective in the genitive case, feminine) is derived from the generic name of the host plant.

Differential diagnosis. The new species, A. onosmae  , can be differentiated from other similar species such as Aceria echii ( Canestrini, 1891)  on Echium vulgare  L. ( Boraginaceae  ) in Italy and Aceria eutricha ( Nalepa, 1894)  on Lappula squarrosa (Ratz.) Dumort.  ( Boraginaceae  ) in Austria by having very long solenidia on both legs (ca. 20). Also in contrast, the new species has pointed dorsal and ventral microtubercles. The prodorsal shield ornamentation of A. onosmae  n. sp. shows that all lines are present on the rear part of the shield. In A. echii  and A. eutricha  , the solenidia are at least twice shorter and there are less microtubercles on the annuli and these are smaller compared to the new species. In A. echii  , the ornamentation occurs on the whole shield in contrast to the new species. The prodorsal shield is smooth in A. eutricha  . Both A. echii  and A. eutricha  cause flower deformation and erinea whereas A. onosmae  sp. n. was observed to have a vagrant lifestyle.
