Family : MICROHYLIDAE
Species : Microhyla (Nanohyla) petrigena
Size (snout to vent) : Female 1.8 cm, Male 1.6 cm

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.
