Buergeria
Buergeria is a genus of frogs in the Rhacophoridae family, and the sole genus of subfamily Buergeriinae. They are the sister taxon for all the other rhacophorids (subfamily Rhacophorinae). This position is firmly supported by the available evidence.
Buergeria are sometimes known as Buerger's frogs. There are four species found in an area that stretches from Hainan (China) and Taiwan through the Ryukyu Islands to Honshu ( Japan).
