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: Acaphyllisa tuberculumae sp. n. on Populus sp. (Salicaceae); Proiectus xiningensis sp. n. on Pinus sp. (Pinaceae); Phyllocoptes beishaniensis sp. n. on Spiraea mongolica Maxim. (Rosaceae); Tetra pruniana sp. n. on Prunus tomentosa Thunb. (Rosaceae) Rupr. (Berberidaceae); Tetra pyriana sp. n. on Pyrus calleryana Decne. (Rosaceae); Tetra simonia sp. n. on Populus simonii Carr. (Salicaceae); Diptacus berberinus sp. n. on Berberis amurensis Rupr. (Berberidaceae); Diptacus mengdaensis sp. n. on Lonicera elisae Franch. (Caprifoliaceae); Rhyncaphytoptus spinus sp. n. on Lonicera rupicola Hook. f. et Thoms. (Caprifoliaceae). Aculops ulmi Hong & Xue, 2005 was re-described.
Eriophyoid mites, Qinghai, taxonomy, new species
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 Aceria paramacrodonis Kuang, 1988 on Lycium sp. (Solanaceae), Aceria qinghaiensis Kuang, 1997 on Salix babylonica L. (Salicaceae), Aculodes salicis Kuang, 1997 on Salix babylonica L. (Salicaceae), Aculops xiningensis Kuang, 2000 on Malus pumila P. Mill. (Rosaceae), Aculus huangzhongensis Kuang, 2000 on Syringa oblata Lindl. (Oleaceae) and Tetraspinus syringae Lin & Kuang, 2001 on Syringa oblata Lindl. (Oleaceae). In July 2007, field surveys were conducted in Qinghai Province, northwestern China. Twenty-five eriophyoid mite samples were collected and 17 eriophyoid mite species were identified, among which nine species were found new to science. No species reported earlier from Qinghai were collected in this survey. In total, there are 23 species of the Eriophyoidea from Qinghai Province, belonging to two families and 12 genera. A list of eriophyoid mites from Qinghai Province is given (Table 1).

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

Lycium sp. (Solanaceae).
Leaf gall; mites produce pocket galls on the lower side of leaves.

Holotype, female (slide number NJAUEri789B, marked Holotype), from Populus sp. (Salicaceae), Xining City, Qinghai Province, P. R. China, 36°38'18"N, 101°45'27"E, elevation 2241m, 21 July 2007, coll. Xiao-Feng Xue. Paratypes, 7 females and 1 male (slide number NJAUEri789B), with the same data as holotype.
Vagrant on leaf lower surface. No damage to the host was observed.
The specific designation tuberculumae is from the character of dorsal opisthosomal microtubercles, “tuberculum” in Latin; masculine in gender.
This species is similar to Acaphyllisa populi Xue & Hong, 2006, but can be differentiated from the latter by prodorsal shield with six cells in the middle (prodorsal shield without cells in Acaphyllisa populi), opisthosoma dorsally with round microtubercles (opisthosoma dorsally with elliptical microtubercles only on ridges in Acaphyllisa populi), female genitalia coverflap smooth (female genital coverflap with 10 longitudinal ridges in Acaphyllisa populi).

Etymology. The specific designation xiningensis is from the place name Xining City, where this new species was collected; feminine in gender.
This species is similar to Proiectus thunbergis Xue, Song, Amrine & Hong, 2007, but can be differentiated from the latter by median and admedian lines of prodorsal shield simple (median and admedian lines with granules in Proiectus thunbergis), opisthosoma dorsally annuli with weak filamentous microtubercles (opisthosoma dorsally annuli with round microtubercles in Proiectus thunbergis), tarsal empodium (em) 5-rayed (4-rayed in Proiectus thunbergis).

Holotype, female (slide number NJAUEri815, marked Holotype), from Spiraea mongolica Maxim. (Rosaceae), Beishan National Forest Park, Huzhu County, Qinghai Province, P. R. China, 36°53'35"N, 102°25'56"E, elevation 2610m, 22 July 2007, coll. Xiao-Feng Xue. Paratypes, 7 females and 2 males (slide number NJAUEri815), with the same data as holotype.
Vagrant on leaf lower surface.
The specific designation beishaniensis is from the place name Beishan National Forest Park, where the new species were collected; feminine in gender.
This species is similar to Phyllocoptes adalius (Keifer, 1939) from Rosa sp., but can be differentiated from the latter by prodorsal shield front lobe stout (prodorsal shield front lobe pointed in Phyllocoptes adalius), dorsal opisthosoma annuli smooth (opisthosoma annuli entirely covered with spinuliferous microtubercles in Phyllocoptes adalius), Coxisternal plates smooth (coxisternal plates with short lines in Phyllocoptes adalius).

This species is similar to Rhyncaphytoptus guanegounis Song, Xue & Hong, 2007b, but can be differentiated from the latter by median, admedian and submedian lines present on prodorsal shield (prodorsal shield smooth in Rhyncaphytoptus guanegounis), prodorsal shield with wide and broad frontal lobe (prodorsal shield with long and broad frontal lobe in Rhyncaphytoptus guanegounis), opisthosomal dorsal annuli with spiny microtubercles (opisthosomal dorsal annuli smooth in Rhyncaphytoptus guanegounis), tarsal empodium (em) 8-rayed (6-rayed in Rhyncaphytoptus guanegounis).
Although Qinghai has climate, vegetation and biological diversity similar to Tibet, we did not find any eriophyoid mite species already reported in Tibet (
