Feihyla kajau — Charming Tree Frog
Also known as:
White-eared Tree Frog
This has got to be one of the cutest frogs in Borneo. It wasn't described until 1984. The Frogs of Borneo book says it is a relatively rare species, known from only a few widely separated locations. But the Frogs of Borneo website says it is quite common in lowland habitats. All I know is that I saw hundreds of frogs in Borneo and I only saw one of these.
