报道了球角跳科在中国的1新纪录属"米氏球角跳属",并描述了1新种,新种命名为鞍山米氏球角跳Mitchellania anshanensis sp.nov.鞍山米氏球角跳与描述自西伯利亚的M.subhorrida Babenko,1994相似,两者的主要区别在于:新种体长仅0.8mm,腹部第5节背面p1毛之间体表颗粒数量为17～20,触角第4节腹面有20～25个弯曲且顶端膨大的短小感觉毛,爪部生有1内齿,但无侧齿,胸部第2和第3节背面感觉毛短小精巧,腹部第1～3节背面感觉毛与普通刚毛长度相同;M.subhorrida体长达到1.5mm,腹部第5节背面p1毛之间体表颗粒数量为8～10,触角第4节腹面弯曲且顶端膨大的短小感觉毛数量范围为30～35个,爪部生有1内齿和1侧齿,胸部第2节、腹部第1～3节背面感觉毛与普通刚毛长度相同,胸部第3节和腹部第2节背面感觉毛短小粗壮.模式标本保存在中国科学院上海植物生理生态研究所.

Mitchellania anshanensis sp. nov. is described and illustrated in the present paper, whichis the first record of the genus Mitchellania from China. The new species is similar to M. subhorrida Babenko, 1994 in appearance, however, it can be separated from the latter by body length, tegumentary granules between the p1 setae of Abd. Ⅴ, ventral setae on Ant. Ⅳ, lateral teeth in claws, lateral sensilla on Th. Ⅱ-Ⅲ and Abd. Ⅰ-Ⅲ, and other features. Holotype and paratypes deposited in Institute of Plant Physiology & Ecology, Shanghai, China.
