Buergeria
Buergeria is a genus of frogs in the family Rhacophoridae, and the sole genus of subfamily Buergeriinae. It is the sister taxon for all the other rhacophorids. The available genetic data firmly supports this position.
Buergeria are sometimes known as Buerger's frogs. The six species are found only in the islands of East Asia, from Hainan and Taiwan through the Ryukyu Islands to Honshu.
Description
Buergeria are medium-sized to large frogs that resemble in their body form Rana. Their skin is smooth and they have no dorsal ornamentations. Their feet are fully webbed whereas their fingers are only up to half-webbed. They produce many eggs that are deposited in water and develop through a tadpole stage.
There are six recognized species in the genus Buergeria:Buergeria buergeri — Kajika Frog. Japan endemic.Buergeria choui Matsui & Tominaga, 2020 — Taiwan and southern Ryukyus.
