During the field study of eriophyoid mites associated with Lamiaceae species in semi-arid and arid environment in East Iran (Birjand, South Khorasan, Iran, summer 2017), two new eriophyid mite species (Trombidiformes: Eriophyidae) were discovered. They are Aceria pocriisp. nov. on Teucrium polium L. and Cecidophyes punctineasp. nov. on Rosmarinus officinalis L., and are illustrated and described herein. Both new species seemed to be vagrants on leaves and flowers, and they were not associated to any particular symptom.
