 Type material. Holotype female (TD 08/02/14) collected from Rosa sp. (Rosa × hybrida; unkn. cultivar of a ground cover rose) in Haifa, Israel (32°49'07"N 34°59'23"E), 16 February 2014, collected by T. Druciarek. Paratypes: 17 females, 10 males, 22 nymphs and 15 larva (TD 05/02/14 -TD 08/02/14) collected from Rosa sp. (Rosa × hybrida; unkn. cultivar of a ground cover rose) in Haifa, Israel (32°49'07"N 34°59'23"E), 16 February 2014, collected by T. Druciarek.   
 Relation to the host plant. All stages of Eriophyes eremus n. sp. were found inside flower buds and in petiole bases. No apparent damage to the host plant was observed.   
 Etymology. The specific name is derived from the Latin noun ‘eremus’ (meaning ‘desert’), in relation to the dry climate of a type locality.

 Remarks. Eriophyes eremus n. sp. is similar in shield pattern to E. rosae (Mohanasundaram 1981), which also inhabits rose plants. However it can be easily differentiated from the latter by the: overall body size (E. eremus 156–214, E. rosae 230–240); genital coverflap with basal part granulated and with only 2–5 curved, diagonal ridges on posterior part (E. rosae 12 vertical lines); and smooth coxal area (with scorings in E. rosae). Both species also differ by the number of opisthosomal annuli (E. eremus 62–69, E. rosae 95), the length of setae 3a (E. eremus 7–10, E. rosae 30), and length of setae e (E. eremus 9–14, E. rosae 25). In addition E. eremus, unlike E. rosae, lacks tubercules and setae h1. Furthermore E. rosae was reported as vagrant, whereas the new species is a refuge-seeking type, inhabiting flower buds and petiole bases.   
 Eriophyes eremus n. sp. is also similar to E. rhodites (Nalepa 1914), however the description made one hundred years ago and lack of drawings as well as type specimens do not allow for precise species comparison. Still a few characters, such as body shape, sculpture of genital shield (smooth in case of E. rhodites and with 2–5 diagonal ribs in case of E. eremus) and prodorsal shield differentiate these two species. According to Nalepa’s description, the sculpture of the prodorsal shield of E. rhodites is composed of lines running from the anterior shield margin to its center, then curving to the lateral margin and back to the sc tubercles. Additional lines on the anterior part of the shield are also present in case of E. rhodites; these lines are divided in the middle of prodorsal shield. Again, the life-style also differentiates these two species as E. rhodites is a vagrant and E. eremus a refugeseeker.
