Distribution and biology. China ( Yunnan, Guangxi, Guangdong); Vietnam. The nymphs ( Fig. 59 View FIGURES 50–59 ) are usually found in slow current reaches of clean mountain streams ( Fig. 67 View FIGURE 67 ) and sometimes with substantial populations on the stone surfaces as indicated from the specimens listed above.

Comments. Described based on nymphs and imagoes from Vietnam in the genus Centroptella ( Soldán et al. 1987) , this species was transferred to the subgenus Chopralla of Bungona by Salles et al. (2016) based on the tarsal claws bearing two rows of denticles. Bungona ( Ch.) liebenauae is here recorded from China for the first time. This species has an unusual characteristics which can easily distinguish it from its congeners: the presence of a pair of submarginal median tubercles posteriorly on pronotum ( Figs 62–63 View FIGURES 60–66 ). Other features, such as base of glossa not reaching inner 1/3 of paraglossa ( Fig. 61 View FIGURES 60–66 ), dentate tarsal claws ( Fig. 64 View FIGURES 60–66 ) and characteristic contrasting body colour pattern ( Fig. 66 View FIGURES 60–66 ), clearly fit the concept of Chopralla proposed by Salles et al. (2016).
