Diagnosis. Cercus ventrally with numerous black, thick spines including ca. four long, inner marginal ones ( Fig. 9DView FIGURE 9). Aedeagus apically with large membranous process which tapering distally in lateral view, subapically swollen dorsally, with a pair of lateral processes, with a pair of lateral processes and a series of small acute projections ventrally ( Fig. 9View FIGURE 9 I–M); lateral processes small, flat, finely serrate on dorsal margin ( Fig. 9I, L, MView FIGURE 9).

Description (characters commonly seen in H. zhangae  sp. nov. not repeated) (♂). Head ( Figs 3E, FView FIGURE 3, 5View FIGURE 5 G–L): Gena yellowish brown to brown, anteriorly dark brown.
