摘　　要：Tibet is a biodiversity-rich area in China. But until now, no water mites have been recorded from Tibet. In this study, two water mite species, Sperchon glandulosus Koenike, 1886 and Sperchon plumifer Thor, 1902 are reported for the first time from Tibet, and Sperchon glandulosus is newly recorded from China. Descriptions and illustrations of Sperchon glandulosus are given herein. DNA barcodings for the two species are also referenced. A key to the 22 species（females） in the genus Sperchon from China is presented.西藏为我国物种多样性非常丰富的地区,但是迄今该地区未有水螨的记录。本文报道采集自西藏的2种水螨:羽足刺触螨Sperchon glandulosus Koenike,1886和伪腺刺触螨Sperchon plumifer Thor,1902,其中伪腺刺触螨为中国新纪录。文中对伪腺刺触螨进行了详细描述,绘制了该种的形态特征图,并提供了本文所采集标本的DNA条形码以及目前中国刺触螨属22种的检索表。
