August 11, 2005 , from Coriaria nepalensis Wall. (Coriariaceae) , coll. Xue, Xiao-Feng and Song, Zi-Wei. Paratypes , 4 females and 2 males , with the same data as holotype . Relation to host. Vagrant on leaf surface. No damage to the host was observed. Etymology. The specific designation coriariae is from the generic name of the host plant, Coriaria . Remarks. This species is similar to Tetra sinicae Li, Wei & Wang, 2006 , but can be differentiated by coxal area with granules (coxal area smooth in T . sinicae ), dorsal annuli with faint microtubercles (dorsal annuli smooth in T . sinicae ), female genital coverflap with 2 transverse lines at base (female genital coverflap smooth at base in T . sinicae ).
