Heriaeus xinjiangensis sp. nov. (figs.1-5)Holotype ♀, allotype ♂, paratypes 3♀♀ 8 ♂♂, yamalikeshan Mountain, Urumqi City (43.8°N, 87.6°E), Xinjiang Uygur Autonomous Region, Liang Tie leg. All the type speciemens are kept in the Department of Plant Protection, August First Agriculture College. Holotype ♀ Total length 8.50, carapace 4.50×4.00, abdomen 4.00×6.00. Body covered by long and white hairs. Anterior furrow of chelicera with 5 denticles, posterior furrow without tooth. Armature of Ⅰ leg: femur with 6 pairs of ventral spines, tibia except with 6pairs of ventral spines, there are 6 prolateral spines and 4 retrolateral spines, metatarsus with 2 rowsof ventral spines, in which the prolateral row with 6 spines and the retrolateral row 9 spines. allotype ♂ Total length 3.50, carapace 1.65×1.55, abdomen 1.85×3.00.
