description: Key to the species of Jucancistrocerus and the related genera from China
1. Pretegular keel absent on the pronotum.................................................................... 2
- Pretegular keel present and developed on the pronotum....................................................... 8
2. Tegula inconspicuously, finely and superficially punctate, usually with only two larger translucent spots (Fig. 70)............................................... Eustenancistrocerus (Parastenancistrocerus) amadanensis (de Saussure, 1855)
- Tegula with dense, strong, sieve-like translucent punctures (Figs 13, 51, 60)....................................... 3
3. T1 short and distinctly wider than long; transverse edge of T1 lying on the level of horizontal area approximately in the middle of this tergum (Fig. 60)................. Eustenancistrocerus (Eustenancistrocerus) askhabadensis (Radoszkowski, 1886)
- T1 elongate and slightly wider than long, or if distinctly wider than long, dorsal surface of propodeum posteriorly with one supercarina extending to lateral side (Figs 5, 14); transverse edge of T1 lower than the horizontal surface and closer to the base of this tergum (Figs 8, 15, 22, 37, 52)............................................... Jucancistrocerus Blüthgen 4
4. Clypeus shallowly emarginated at apex (Figs 3–4, 11); T1 much wider than long and somewhat narrower than (more than 0.8×) T2 (Figs 8, 15)....................................................................................... 5
- Clypeus more deeply emarginated at apex, and tooth-like laterally (Figs 19–20, 34–35, 45–46, 49–50); T1 elongate, a little wider than long and distinctly narrower than (less than 0.8×) T2 (Figs 22, 37, 52).................................. 6
5. Body more coarsely punctate (Figs 1–4, 8–9); apical margin of clypeus emarginated and incised (Figs 3–4); mesoscutum without or with one smaller subapical spot (Figs 1–2)..................... J. (Eremodynerus) atrofasciatus (Morawitz, 1885)
- Body less sparsely punctate (Figs 10–12, 15–16); apical margin of clypeus slightly emarginated; mesoscutum medially with one big subapical spot (Fig. 10).............................................. J. (E.) chotanensis (Blüthgen, 1942)
6. Clypeus coarsely punctate in both sexes, and apex relatively narrower (in female apical width: depth of emargination= 2.89, in male apical width: depth of emargination=2.57) (Figs 49–50).......... J. (Jucancistrocerus) tachkensis (Dalla Torre, 1889)
- Clypeus less sparsely punctate, and apex wider (in female apical width: depth of emargination=3.32–3.96, in male apical width: depth of emargination=1.99–2.25) (Figs 19–20, 30–31, 34–35, 45–46)........................................... 7
7. Both female and male clypeus widely and shallowly emarginated at apex (Figs 34–35, 45–46); male A13 hooked backward not reaching the base of A11 (Fig. 39); volsella (Fig. 40) apically narrower and sharper..... J. (J.) angustifrons (Kostylev, 1940)

8. Transverse edge of T1 lying below the level of horizontal surface of this tergum (Fig. 88); T3 much coarser in the distal portion than at the base of T2 (Fig. 89); clypeus truncate and narrow at apex (83–84)...................................................................................................... Tachyancistrocerus schmidti (Kokujev, 1912)
- Transverse edge of T1 lying at the level of the horizontal surface (Fig. 77); punctures on T3 not coarser than those of T2 (Fig. 79); clypeus deeply and widely emarginted at apex (Fig. 74)............................................................................................. Stenancistrocerus (Paratropancistrocerus) transcaspicus (Kostylev, 1934)
