Figure 5 in A gall mite, Aceria rhodiolae (Acari: Eriophyidae), altering the phytochemistry of a medicinal plant, Rhodiola rosea (Crassulaceae), in the Canadian Arctic
Figure 5. Coxigenital region of Aceria rhodiolae females from (A) Russia, and (B,C,E) Nunavik, Canada. (A,B) Differential interference contrast light microscopy, (C,E) scanning electron micrograph, (D) line drawing. Scale on (B) also applies to (A). Notations on (D) indicate palp, leg and idiosomal setae, and coxal apodemes (ap1, ap2, ap; pra, prosternal apodeme). Other arrows elsewhere indicate characteristic ridges on coxal plates (a,b,c); genital flange (fl), and underlying postgenital plate (pp), which bears setae 3a and extends anterolaterally into lateral flaps (f) that flank the genital coverflap; and ventral ridges on femur, genu, and coxal fields (E).

Figure 8. (A) Healthy infructescence of a Rhodiola rosea plant from Nunavik (Canada) versus (B) a mite-infested inflorescence (mostly pale green or yellowish) that partly (centrally) developed into fruits (yellow to red). (C) Dried inflorescences from Labrador (Canada) with a few (upper right) to most (lower left) flowers galled, and a galled leaf (isolated, in the middle). (D) Dried inflorescences from western Russia that were preserved in an herbarium for over 100 years. (E,F) Enlargement of a galled flower and galled leaf from Labrador (same scale). Arrows point at some of the galled flowers (B‒D) or leaves (C). The scale on (C) also applies to (D), and is approximate for (A,B).
