Saffron-bellied Frog 
Chaperina fusca
   
   

Family : MICROHYLIDAE
Species : Chaperina fusca
Size (snout to vent) :  Female 2.6 cm, Male 2.1 cm

The Saffron-bellied Frog, or Yellow-spotted Narrow-mouthed Frog, occurs in primary or mature secondary forest in hilly areas and adjacent lowlands.

It is typically found on the forest floor or on top of boulders, but it may also climb up onto rocks or tree trunks.

Its colour and patterning are of a style not typically seen in frogs of Southeast Asia. Its most obvious identifying feature are the large yellow spots on the belly. The dorsal surface may be more varied: it is generally brown or black, but is sometimes greyish, and is typically patterned with small bluish or greenish spots. In some specimens these spots may be much larger, and these sometimes coalesce such that bluish-grey may be the dominant colour.

This species is known to occur in parts of Peninsular Malaysia (mainly in the states of Perak and Pahang, including Pulau Tioman), Borneo and some islands of the southern Philippines (Palawan, Mindanao and Jolo). Its status in southern Thailand is unclear.
