Male and larva unknown.
Type material: Holotype female (Thf-3) found in Feizabad of Torbat Heidariyeh, Razawi Khorassan province, Northeastern Iran, 34° 57.380 N, 58° 45.301 E, altitude 895 meters, from under elytra of Cymbionotum semelederi ( Coleoptera : Carabidae ), collected by Hamidreza Hajiqanbar, 5 May 2007.
Paratypes- 8 females, same collection data as holotype.
Type depositories: Holotype deposited in the Acarological Collection, Department of Entomology, Faculty of Agriculture, Tarbiat Modares University, Tehran, Iran. One paratype to each of the following: Zoological Institute, University of Hamburg, Hamburg, Germany; U.S. National Museum of Natural History, Washington D.C., U.S.A.; Collection of Nikita Botanical Gardens, Yalta, Ukraine and Acarological Collection, Zoological Museum, College of Agriculture, University of Tehran, Karaj, Iran. Balance of paratypes deposited with the holotype.
Etymology: The name of the new species refers to 4 discoidal suckers on ventral side of the female body.
Bionomics: The mites were found two times (3 mites on one beetle and 5 mites on another beetle) from under elytra and dorsal metathoracic tergites of Cymbionotum semelederi (Chaudoir, 1851) ( Coleoptera : Carabidae : Melaeninae: Melaenini). Based on Ball and Shpeley (2005), the genus Cymbionotum Baudi di Selve, 1864 includes 20 species, arranged in two subgenera. In the Eastern Hemisphere, the subgenus Cymbionotum (sensu stricto) includes 18 species in three species group. Among them, the semelederi species group occupies the temperate grassland vegetation zone, and marginally, the desert and semi-desert zone and is distributed in Palearctic Region from western Asian Afghanistan to northwestern Africa, and across the northern part of the Afrotropical Region.
