This stunning, but tiny,
frog occurs in moist lowland rainforests of Borneo. It congregates at swampy
pools or flooded areas and may be found either resting on the substrate or
clinging to nearby vegetation.
Its patterning is most attractive, comprising complex arrangements of dark
brown patches on its back and legs, edged with pale yellow or orange and set
against a brown or purplish-brown background. There are black patches near
the ankles and sides of the thigh, and a distinctive oblique pale stripe
below each eye.
The hindlimbs are robust and strong, while the forelimbs are quite slender.
The forefeet have only three toes.
Reaching a maximum size of just 18 mm, this species is one of the smaller
species of Chorus Frog (or Narrow-mouthed Frog).
Microhyla petrigena only occurs in Borneo.
