Snout:
- Long and pointed, longer than the eye (Snout Length: 8.69 mm, Eye Diameter: 5 mm).
- Blunt rostral ridge.
- Slightly concave and oblique loreal region.
- Round nostrils, closer to the tip of the snout than to the eye.
- Inter-nostril distance wider than interorbital distance.
- Eye diameter larger than the upper eyelid width and the interorbital distance (Eye Diameter: 5 mm, Upper Eyelid Width: 4.38 mm, Interorbital Distance: 4.28 mm).
- Tympanum distinct, with a diameter approximately two-thirds of the eye diameter (Tympanum Diameter: 3.52 mm).
- Vomerine teeth arranged in two V-shaped rows.
- Tongue long, notched posteriorly.
- Males possess two vocal sacs.
Limbs:
- Fingers completely free.
- Webbing present on the hind feet, extending approximately one-third of the toe length.
- Long inner metatarsal tubercle, small outer metatarsal tubercle.
- When the hind limbs are folded along the body, the tibiotarsal joint reaches the middle of the eye, and the tarsometatarsal joint reaches the tip of the snout.
- Distinct dermal ridge above the tympanum.
- Dorsum marked with numerous short skin folds.
Coloration:
- Coloration varies among individuals.
- Dorsal surface of the head and back are moss green or light brown.
- A dark V-shaped marking is usually present between the eyes.
- A light stripe may be present along the dorsal midline, extending from the tip of the snout to the anterior of the cloaca, sometimes widening on the head but narrowing posteriorly.
- Ventral surface and underside of limbs are white.
- Hind limbs exhibit dark transverse bands.
Biology and Ecology:
- Commonly found in humid environments within evergreen forests, rice fields, along streams, and in gardens.
- The breeding season typically extends from March to June, or later depending on the region.
- During the day, they take shelter in depressions in the ground or crevices, emerging to forage at dusk.
- They are adept jumpers, capable of leaping approximately 2 meters, and are also good swimmers.
- Their primary food sources are ants, termites, and terrestrial insects.
