Etymology — This species is named in honor of the city of Khorramabad, capital of Lorestan province, where the new species was collected.

Type materials — The holotype female and two paratype females and five allotype males were collected from soil and litter under oak trees, Quercus brantii Lindl (Fagaceae) , Kaka Reza region , Khorramabad vicinity, Lorestan province (33°56’N, 48°39’E, a.s.l. 1703 m), 19 xi 2011, by Mohammad Ahmad Hoseini. The holotype female and one paratype female, four allotype males are deposited in the Collection of the Acarology Laboratory, University of Bu-Ali Sina , Hamedan, Iran . One paratype female, one male slide is deposited in the mite Section of National Collection of Arachnida, Plant Protection Research Institute, Pretoria, South Africa .
