Material examined. Holotype ♀, Bayannur, Inner Mongolia, 40 ° 28 ' N, 108 ° 11 ' E, elev. 1022 m, ex. Setaria viridis (L.) Beauv., 21 July 2017, coll. Ruixia Meng and Qingyan Liu. Paratypes. 9 ♀ 7 ♂, same data as holotype; 6 ♀, 13 September 2020, others same as holotype; 17 ♀ 9 ♂, 3 November 2020, others same as holotype. Etymology. The specific name setarius is derived from the genus name of the host plant Setaria. Remarks. This new species is similar to N. bicaudus (Wainstein, 1962), N. micmac (Chant & Hansell, 1971) and N. brachychaetus Kolodochka, 2018. Its adult males can be easily distinguished from others by having setae R 1 off dorsal shield (vs. R 1 on dorsal shield in the latter three species). Detailed comparative information see Table 1. This new species can be included in the paraki species subgroup. In addition, variation in the structure of a few setae was found: S 5 are barbed (20 out of 33 specimens, 60.6 %) or smooth (39.4 %), JV 5 are usually smooth (29 out of 33 specimens, 87.9 %).	en	Ma, Min, Liu, Yu, Li, Yujing, Fu, Xiaotong, Fan, Qinghai, Meng, Ruixia (2023): Morphological characteristics of Neoseiulus setarius Ma, Meng & Fan, sp. nov.
