(Scale bar: CGF, D, L — 55; E — 9; GM — 36; L1, L2 — 24). Male (n=4). Body fusiform, 122−125, 38−40 wide. Male genitalia 15−17 wide, proximal setae on coxisternum ІІ ( 3a ) 9−10, 14−15 apart. Type data. Holotype , female, Jianshi National Forest Park, Tian’er County ( 25°01'N , 107°16'E ), Guangxi Zhuang Autonomous Region, China , 18-Aug.-2006 , from Luculia sp. (Rubiaceae) , collected by GuoQuan Wang, AiZhi Qin and SuiGai Wei. Paratypes , 13 females and 4 males , were mounted on each individual slide, with the same data as the holotype . Relation to host. The mites are vagrant on the undersurfaces of the leaves, no visible damage seen. Etymology. The specific designation is derived from the generic name of the type host plant.
