Family : DICROGLOSSIDAE
Species : Limnonectes malesianus
Size (snout to vent) :
Female & Male >10 cm

A nocturnal forest species, which at night may venture into clearings. The dorsum is generally a reddish or reddish-brown colour, and the throat is mottled. There is a pale, thin vertebral stripe.  

 
   
 
  Distinguishing features :
Top : The dark blotch on the tympanum.
Bottom : The 'W' shaped skin folds on the back.
   

In the field it can be distinguished from similar species, such as the Malayan Giant Frog Limnonectes blythii, by the sharp angle of the skin fold behind the tympanum, by the clearly defined black patch on the upper part of the tympanum, and by the 'W' shaped skin folds on the back.

It occurs in Peninsular Malaysia and Singapore, Sumatra, Borneo and Java.
