 Type material. Holotype , female (slide number NJAUAcariEri329, marked Holotype), from Salix sp. L. (Salicaceae), Changqing Nature Reserve, Huayang Town, Yang County, Shaanxi Province, P. R. China, 34°41'57' N, 107°37'09' E, elevation 2187m, 9 August 2005, coll. Xiao-Feng Xue & Zi-Wei Song. Paratypes, 12 females (slide number NJAUAcariEri329), with the same data as holotype.   
 Relation to host. Vagrant on leaf surface. No damage to the host was observed.   
 Etymology. The specific designation changqingiensa is from the location name, where the new species were collected.   
 Differential diagnosis. This species is similar to Acaphyllisa adamantis Song, Xue & Hong, 2008, but can be differentiated from the latter by setae h1 present (setae h1 absent in Acaphyllisa adamantis), dorsal annuli with microtubercles (dorsal annuli smooth in Acaphyllisa adamantis), and admedian and submedian lines connected (admedian and submedian lines separated in Acaphyllisa adamantis).   
 Note. The new species co-occurred with Aculops salixis Xue, Song & Hong 2007.
