Family : MICROHYLIDAE
Species : Metaphrynella sundana
Size (snout to vent) : Female 2.5 cm, Male 2.3 cm

The Bornean Treehole Frog occurs in lowland primary or secondary rainforest up to an elevation of around 700 metres. It is smaller in size than its cousin the Malayan Treehole Frog Metaphrynella pollicaris: the female of the species measures just 2.5 cm snout-to-vent and the male is slightly smaller.

In similar fashion to the Malayan Treehole Frog, the males of this species select a suitable treehole from which they call persistently in an attempt to attract a female inside for mating. They vary the pitch of their call to match the resonance of their chosen treehole or other hollow.

This frog is typically mottled brown in colour, and its skin is warty in texture. Its head is small, its snout short and blunt, and its eyes of medium size. Great variation in colouration is reported, however.

The photos at left illustrate a typical treehole, with a resident male.

This species occurs only on the island of Borneo.
