【Abstract】 A new species of Brivbia from Xinjiang, China, is described in this paper. The type specimens are deposited in Shihezi Agricultural College, Xinjiang.Bryobia nitrariae sp. nov. (Figs. 1-9)This new species is similar to Bryobia tadjikistanica Livshitz et Mitrofanov in propodosomal lobes and true claw of leg I , but differs from the latter in the following characters: (1) spermatheca shaped like a calabash, 22μm in length, maximum width 14μm; (2) true claw on legs Ⅱ - IV talon-shaped. The spermatheca of B. tadjikstanica is long and the true claws on legs Ⅱ - IV are hookshaped. This makes it easy to distinguish the two species.Holotype , para types 6 , Tuoli County, Xinjiang U ygur Autonomous Region, 15-Ⅷ- 1987, collected by Tan Ruicheng.Host plant: Nitraria sibirica Pall.更多还原
