MALE: Unknown.  
 Type material. Holotype , female (slide number NJAUAcariEri337A, marked Holotype), from Cornus alba L. (Cornaceae), 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 NJAUAcariEri337A), with the same data as holotype.   
 Relation to host. Vagrant on leaf surface. No damage to the host was observed.   
 Etymology. The specific designation albus is from the species name of host plant, alba.   
 Differential diagnosis. This species is similar to Tegonotus tinctoriae Wei, Wang & Li, 2009 (Wei et al. 2009), but can be differentiated from the latter by dorsal annuli with filamentous microtubercles (dorsal annuli smooth in Tegonotus tinctoriae), tarsal empodium 4-rayed (tarsal empodium 5-rayed in T. tinctoriae), and coxal plates with granules (coxal plates smooth in Tegonotus tinctoriae).   
 Note. The new species occurred with Apodiptacus albae Wang, Xue & Hong, 2009.
