039787AC9E4AFFA99FB38996FCD79303.taxon	etymology	Etymology. The specific name is derived from a noun in apposition of the type locality.	en	Lin, Yucheng, Li, Shuqiang (2010): New armored spiders of the family Tetrablemmidae from China. Zootaxa 2440 (1): 18-32, DOI: 10.11646/zootaxa.2440.1.2, URL: https://biotaxa.org/Zootaxa/article/view/zootaxa.2440.1.2
039787AC9E4AFFA99FB38996FCD79303.taxon	diagnosis	Diagnosis. The new species seems closest to Tetrablemma loebli Bourne, 1980 but differs by 1) the presence of a tibial and two metatarsal tuber distally, 2) the longer apophysis at chelicera anteriorly, 3) the pedipalpal tibia swollen, subequal to femur in length, 3) the longer and narrower pedipalpal bulb, 4) the short and horny embolus. In addition, 5) the cephalica pars upheaved, higher than ocular area in male, 6) the triangular epigynal pit and 7) the difference in central process and inner vulval plate, can also easily distinguished from its congeners.	en	Lin, Yucheng, Li, Shuqiang (2010): New armored spiders of the family Tetrablemmidae from China.
