Size (snout to vent) : at least 6 cm
Also known as the
Three-striped Frog, or Khao
Wang Frog, after the location in Thailand where it was first described, the
Slashed-back Frog is a species of lowland forests where it frequents
shallow pools and swampy areas. It has also been recorded in disturbed,
riverine forest.
The shape of this frog is typically ranid (i.e. like a 'true frog'), and the
body colour is highly variable, ranging from yellow or greenish-yellow to
dark brown or greyish.
The distinguishing feature is the
oblique scar-like lines on the dorsum of which there are typically three
but, as in the example shown in Figure 2, there may be a more complex
arrangement of numerous lines of varied length. These diagonal lines are
apparent on late-stage tadpoles (Fig. 3).
The call of the adult frog is like a rapidly repeated
dog's bark.
This species occurs in
southern Thailand and Peninsular Malaysia. It has not been recorded from Singapore.
