Type material. Holotype female (slide number IR93-AH7, marked holotype), from Marrubium vulgare L. ( Lamiaceae ), Chahardeh (32°51'58''N, 59°13'16''E), Birjand, South Khorasan province, Iran, 15 April 2014, coll. A. Honarmand and H. Sadeghi, 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 IR93-AH7), from Marrubium vulgare L. ( Lamiaceae ), Chahardeh (32°51'58''N, 59°13'16''E), Birjand, South Khorasan province, Iran, 15 April 2014, coll. A. Honarmand and H. Sadeghi, deposited in the Arthropod/Mite Collection of the Department of Entomology, NJAU, Jiangsu Province, China; 7 females on seven slides (slide number IR93-AH7) from Marrubium vulgare L. ( Lamiaceae ), Chahardeh (32°51'58''N, 59°13'16''E), Birjand, South Khorasan province, Iran, 15 April 2014, coll. A. Honarmand and H. Sadeghi, deposited in the Department of Plant Protection, FUM, Iran.

Relation to host. This species is vagrant on both sides of the leaf surfaces. No damage to the host plant was observed.

Etymology. The specific designation marrubiumer is derived from the generic name of the host plant, Marrubium ; masculine in gender.

Differential diagnosis. The new species is different from all others in the genus, except for the species Tegolophus glochidionis Kuang & Lin, 2001 , T. braziliensis Keifer, 1969 and T. pfaffiae Keifer, 1963 , because it has dorsal annuli with round microtubercles, coxal plates with short lines or granules, seta h1 present, tarsal solenidion rod-like and median line absent from prodorsal shield. The new species can be separated from these three species in the following manner: having the admedian lines separated (admedian lines connected in T. glochidionis ); V-shaped mark absent between admedian lines (V-shaped mark present in T. braziliensis ); and empodium 7-rayed (empodium 5-rayed in T. pfaffiae ).
