Type material. Holotype female, 4 female paratypes and 2 deutonymphs collected from Rubus persica L. ( Rosaceae ), IRAN: Kurdistan Province, Sanandaj, Angozhan village, 35°05ʹN, 46°55ʹE, 1309 m a. s. l., 9 October 2009, coll. M. Khanjani.

Type deposition. Holotype female, 3 female paratypes and 1 deutonymph – CALBS; 1 female paratype and 1 deutonymph – QMA.

Etymology. The species is named after its host genus, Rubus .

Remarks. Cenopalpus rubusi resembles C. irani Dosse, 1971 in having its propodosomal setae narrowly lanceolate. However it differs from the latter by lacking opisthosomal pores, having a rostral shield with four acute lobes medially (compared with two broad lobes), the region between coxae III–IV with transverse striae (smooth in C. irani ) and the metapodosomal venter reticulate anterior to the ventral plate (smooth in C. irani ).
