Notes. According to references and specimens, it is verified that J. (J.) tachkensis ( Dalla Torre, 1889) (Fig VI-4, in Li 1985) was misidentified, and Li’s (1985) specimens actually belong to Pararrhynchium ornatum multifasciatum Giordani Soika, 1986 . To date, J. (J.) tachkensis is distributed in Xinjiang rather than Jiangsu, Zhejiang or Sichuan of China.

Diagnosis. This species, Jucancistrocerus (Jucancistrocerus) tachkensis , is similar to J. (J.) alashanicus with almost the same color pattern ( Figs 47–54 ), but its clypeus sculpture is obviously coarser and denser ( Figs 49–50 ), the tegula has bigger and denser punctures ( Fig. 51 ). The clypeus is densely and coarsely punctate, punctures a little sparser in males, the clypeus in females is wider than (1.11×) long and in males longer than wide (1.15×) and apically with deep and rounded emargination in both sexes, apex relatively narrower (female apical width: depth of emargination = 2.89, male apical width: depth of emargination = 2.57); male A13 backward, not reaching the apex of A11 ( Fig. 54 ). Propodeal margin between dorsal and lateral surfaces with tooth-like protuberance; T1 ( Fig. 52 ) wider than (1.48×) long and narrower than (0.76 ×) T2; volsella ( Fig. 55 ) apically narrower and sharper, penis valve ( Fig. 55 ) near the base distinctly with one angular protrusion.

Distribution. China (new record: Xinjiang); Uzbekistan; Turkmenistan; Afghanistan; Pakistan.
