Amolops mengyangensis
Amolops 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. Taxonomy Amolops mengyangensis was described in 1995 based on two males and one female collected in 1957 from Yunnan. The specimens had previously been reported as Amolops chunganensis, and this view was maintained by some later authors. Rana daorum was described in 1995 based on specimens from northern Vietnam. In 2007, Ohler concluded that Rana daorum is a junior synonym of Amolops mengyangensis, but this conclusion was challenged by Stuart, Biju, and others who considered it valid as Amolops daorum. As of late 2018, the Amphibian Species of the World and AmphibiaWeb databases recognize both Amolops mengyangensis and Amolops daorum as valid species. Description Males measure in snout–vent length, whereas females can reach in snout–vent length. The snout is long and blunt.
