Eriophyoid mites from Qinghai Province, northwestern China were studied herein. Up to now, only six species have been reported from Qinghai Province. In field surveys, 17 eriophyoid mite species were collected, among which nine species were found new to science. The new species and their host plants are listed as follows:
Qinghai Province (89°35'E–103°04'E, 13°39'N–39°19'N), located in the northwest of the People’s Republic of China, is a part of the Qinghai-Tibet Plateau, with an average elevation of over 3000m (1650m–6860m). The average temperature ranges from 0.4°C to 7.4°C. (
Up to now, six species of eriophyoid mites from Qinghai have been reported. They are

In the field, eriophyoid mites were collected by the aid of a hand-lens (30X) from the lower surface of host plant leaves. Eriophyoid mites, together with host plants, were immersed in 75% alcohol and kept in vials. Each vial was marked with the collection data, such as specimen number, collection date, host plant, mite color, location, collector, and mite relationship to host plant. The collection data were also recorded in the collection notebook for further use. The host plants were kept in a plant specimen folder in a dry environment.
The morphological terminology used here follows that of
Leaf gall; mites produce pocket galls on the lower side of leaves.
China (Gansu, Ningxia, Qinghai, Shandong).
The mites produce pockets on the lower surface of the leaves.
