WAcrossocheilus yunnanensis is a species of cyprinid fish. It occurs in eastern Yunnan province in China.
WAmolops mengyangensis is a species of frog in the family Ranidae. It is known with certainty only from its type locality, the eponymous Mengyang in Xishuangbanna Dai Autonomous Prefecture, southern Yunnan province of China. However, if Amolops daorum is its junior synonym, distribution of Amolops mengyangensis would be considerably wider, including the vicinity of Sa Pa in northern Vietnam near the Chinese border, Hong Kong, and Houaphanh Province in eastern Laos, and presumably also including the intervening areas. This more inclusive species circumscription was taken in the latest assessment of this species for the IUCN Red List of Threatened Species from 2008.
WAnabarilius macrolepis is an extinct species of ray-finned fish in the genus Anabarilius that was endemic to Yilong Lake in Yunnan, China. It is believed that it became extinct when Yilong Lake dried up in 1981, as a result of water abstraction for agriculture. The species was not observed in 1983–84, and was declared extinct in 2011.
WBannana is a genus of goblin spiders native to Xishuangbanna prefecture, Yunnan Province, China, where it lives in the leaf-litter of tropical rainforest. There are two known species: Bannana crassispina and B. parvula, both described in 2015. Individuals are pale yellow and unpatterned, and range from around 1.0 to 1.8 mm in body length, with females being slightly larger than males. The eyes are reduced or entirely absent. Known only from a nature reserve in Xishuangbanna, Bannana belongs to a group of Asian goblin spiders known as the "Dysderoides complex", that ranges from China to Pakistan and south to Indonesia.

WThe Yunnan box turtle is a species of turtle in the family Geoemydidae. It is believed to be endemic to Yunnan, China and was suspected to be extinct since the early 20th century; the last verified specimen was collected in 1940.
WThe Yunnan lake newt is an extinct species of newt in the family Salamandridae, and was also known as Wolterstorff's newt. It was only found near the Kunming Lake in Yunnan, China. It was found in shallow lake waters and adjacent freshwater habitats. Despite extensive surveys, it has not been seen since 1979, and is therefore considered extinct. The reasons for its extinction are believed to be habitat loss, pollution, and introduced species.
