Holotype , female (slide number Iran 111, marked holotype), from Prunus dulcis (Mill.) (Rosaceae), Robat, Birjand, South Khorasan Province, Iran, 23 June 2010, coll. H. Sadeghi and F. Darmiani, deposited as a slide mounted specimen in the Arthropod/Mite Collection of the Department of Entomology, NJAU, Jiangsu Province, China. Paratypes, 2 females (slide number Iran 112–113), from Prunus dulcis (Mill.) (Rosaceae), Robat, Birjand, South Khorasan Province, Iran, 23 June 2010, coll. H. Sadeghi and F. Darmiani, deposited in the Arthropod/Mite Collection of the Department of Entomology, NJAU, Jiangsu Province, China; 5 females on five slides (slide number Iran 113.2–113.6) from Prunus dulcis (Mill.) (Rosaceae), Robat, Birjand, South Khorasan Province, Iran, 23 June 2010, coll. H. Sadeghi and F. Darmiani, deposited in the Department of Plant Protection, FUM, Iran. Host plant. Prunus dulcis (Mill.) (Rosaceae). Relation to host. This species is vagrant on both leaf surfaces. No damage was observed. Etymology. The specific designation robaticus is from the name of the location, Robat, where the new species was collected. Differential diagnosis. This species is similar to Colomerus pruni Kuang and Luo 2005 [from Prunus pseudocerasus Lindl. (Rosaceae)], but can be differentiated from the latter by having smooth coxal plates (with short lines in C. pruni), setae h1 absent (present in C. pruni), admedian and submedian lines present on the prodorsal shield (admedian and submedian lines absent in C. pruni).
