摘要
Two new water mites species of the genus Sperchon Kramer, 1877 from China, Sperchon synsetus sp. nov. and Sperchon xiaoqikongensis sp. nov. are described and illustrated in this article. Sperchon synsetus sp. nov. differs from known species of the genus in the following: cuticle covered with very fine spinules arranged in polygonal pattern and each polygon with an annular line inside; two peg-like setae fused at the base on the ventral side of P-IV. Sperchon xiaoqikongensis sp. nov. is characterized by cuticle covered with scale-shaped papillae; P-II with an obtuse projection bearing three setae and A1 setae is plumose. To the present, 18 species of the genus Sperchon have been described from China.
