All three species share a similar habitus, e. g., a smaller body size, and a shallow and short longitudinal impression of the pronotum. The new species can be easily distinguished from Z. tangliangi and Z. yingzuijieensis by the base of the pronotum with several pairs of small granules at middle (vs. with a pair of small foveae in the same position in Z. tangliangi and Z. yingzuijieensis) and the very different form of the aedeagus (aedeagus much slenderer and the anterior pair of sclerites much smaller in Z. tangliangi and Z. yingzuijieensis; Jiang and Wang 2021; Jiang and Chen 2023).</p></div>	https://treatment.plazi.org/id/15126497F19F5E12B3D0D4043247CBBF	Public Domain	No known copyright restrictions apply.
