The Huanren frog (Rana huanrensis) is a species of true frog found in East Asia. It was originally believed to be endemic to Huanren County, Liaoning, China, but was later also found in South Korea; it is presumed to be present in North Korea, as well. [1] It is closely related to the Dybowski's frog, Rana dybowskii, and specimens collected before 1991 were incorrectly identified as that species. Distinguishing factors include the absence of a vocal sac. [2]
The Huanren frog is found in and around rivers and streams in hilly terrain. The type locality in Huanren is 520 m (1,710 ft) above sea level, and specimens from Korea have also only been found at altitudes over 500 m (1,600 ft). Specimens from South Korea have been collected in the provinces of Gangwon-do, Gyeongsangbuk-do, and eastern Gyeonggi-do. Egg clutches, which are small and clustered, are deposited on submerged rocks in the streams which this species favors.
