The new species clearly differs from  B. martii n. comb.by the absence of eyes and by much more slender and longer pedipalps (e.g. femur 7.0-7.7 times, length 2.17-2.33 vs 4.25 times, length 1.58).  Bisetocregaris cavernarum n. sp.and  B. chuanensis n. sp.possess two or four indistinct eyes (vs absence of eye-spots in  B. baozinensis n. sp.) and have stouter and shorter pedipalps (e.g. femur max. 5.8 times longer than broad, length max. 2.10 vs min. 7.0 times, length min. 2.17 in  B. baozinensis). 1324024074 2014-04-22 MSWU Yunchun Li & Yu-Cheng Lin China 954 28.01458 Yu Hua Town 106.05209 Gu Lin 5 264 1 1 Sichuan Province holotype
