Key to subgenera of ChorebuS in China

(modified after Tobias et al. 1986 and Tobias 1998)

1. Hind coxa with a distinct tuft of pubescence on its dorsal part; mesosoma usually elongate (at least 1.3× as long as high); vein 3-SR+SR1 of fore wing more or less evenly curved; first metasomal tergite usually long and parallel-sided; precoxal sulcus very long............................................................................................. 2

- Hind coxa without any tuft of pubescence on its dorsal part; if slightly developed tuft present, then mesosoma relatively short, not more than 1.3× as long as high........................................................................3

2. Vein 3-SR+SR1 of fore wing rather evenly curved; mandibles thin and long, almost with 3 teeth since the third tooth (additional tooth) degenerates into a faint projection; labial palps with 3 or 4 segments................Subgenus Chorebus s.str.

- Vein 3-SR+SR1 of fore wing relatively not so evenly curved, and its apical half usually S-shaped bend or straight; mandibles distinctly with 4 teeth, if seemingly with 3 teeth, then relatively wide; labial palps with 4 segments...................................................................................................Subgenus Phaenolexis Förster

3. Hind coxa smooth; metapleuron with a small somewhat glossy tubercle surrounded by dense semi-appressed long pubescence forming a distinct rosette, or tubercle relatively weak and without long pubescence; second metasomal tergite always smooth...............................................................................Subgenus Stiphocera Förster

- Hind coxa distinctly rugose, at least on its basal part; metapleuron with a rugose swelling on its lower half, with long pubescence but not forming a distinct rosette; second metasomal tergite often with rugosity............Subgenus Etriptes Nixon
