| Popis: | Habitat loss poses a grave threat to endemic species with narrow distributions. Some species become extinct even before scientific identification due to habitat destruction. Here, a probable example is reported based on some recent and subfossil shells from an almost disappeared wetland lake in Yunnan Province, China. A new ornamented freshwater snail species, Tchangmargarya ziyi n. sp., is recognised and described based on morphological comparison with the other Tchangmargarya species. The subfossil specimens of the new species show a great similarity to Tchangmargrya yangtsunghaiensis (Tchang & Tsi, 1949), indicating their potentially close relationship. The discovery of the new species demonstrates that the plateau lakes of Yunnan, even the small ones, have a high biodiversity and endemism. Furthermore, it enriches the knowledge of the distribution of Tchangmargarya and provides further evidence that the Liangwang Mountains are a significant biogeographic barrier to three endemic viviparid gene... |
