 Type material. Holotype  female (slide number Iran 60.1, marked holotype), from Haloxylon persicum Bunge ex Boiss. et Buhse (Chenopodiaceae), Kashmar, Razavi Khorasan Province, Iran, 1 June 2010, coll. Hussein Sadeghi, deposited as a slide mounted specimen in the Arthropod/Mite Collection of the Department of Entomology, NJAU, Jiangsu Province, China. Paratypes: 2 females and 1 male (slide number Iran 60.1, on the same slide with holotype), 1 female (slide number Iran 60.2), from Haloxylon persicum Bunge ex Boiss. et Buhse (Chenopodiaceae), Kashmar, Razavi Khorasan Province, Iran, 1 June 2010, coll. Hussein Sadeghi, deposited in the Arthropod/Mite Collection of the Department of Entomology, NJAU, Jiangsu Province, China; 20 females and 5 males on 18 slides (slide number Iran 60.3–60.20) from Haloxylon persicum Bunge ex Boiss. et Buhse (Chenopodiaceae), Kashmar, Razavi Khorasan Province, Iran, 1 June 2010, coll. Hussein Sadeghi, deposited in the Department of Plant Protection, FUM, Iran.   
 Host plant. Haloxylon persicum Bunge ex Boiss. et Buhse (Chenopodiaceae).   
 Relation to host. This species was found feeding inside deformed buds. Infested tissues were deformed into green masses which remained on the foliage throughout the growing season.   
 Etymology. The specific designation haloxylonum is from the generic name of host plant, Haloxylon.   
 Differential diagnosis. This species is similar to Aculops wenxianensis Song, Xue and Hong 2006 [from Melia azedarach L. (Meliaceae)], but can be differentiated from the latter by having a prodorsal shield with a median line (absent in A. wenxianensis), dorsal annuli with elliptical microtubercles (only with elliptical microtubercles at lateral areas in A. wenxianensis), empodia 4-rayed (5-rayed in A. wenxianensis).
