Male and larva
Male and larva unknown.
Type material
Holotype female (Thf-3) found in Feizabad town of Torbat Heidariyeh, Razawi Khorassan province, northeastern Iran, 34°57.380′ N, 58°45.301′ E, altitude 895 m, collected by Hamidreza Hajiqanbar, 5 May 2007. The mites were found twice (five mites on one carabid beetle and three mites on another carabid beetle of a different species) phoretic on ventral body surfaces, grasping hairs of abdomen and thorax of Cymbionotum semelederi (Chaudoir, 1851) ( Coleoptera : Carabidae : Melaenini) and Siagona europaea Dejean, 1826 ( Coleoptera : Carabidae : Siagonini ), possessing five and three mites, respectively. The beetles were captured by attracting them to a light trap.
Paratypes. seven females (Thf-3 and Thf-5), same collection data as holotype .
Etymology
The name of the new species refers to the trichobothridium of this mite in which sensillum has a somewhat unusual form among heterostigmatic mites.
