Mackay's Tree Frog

Males grow to 36 mm (1.4 in) and females to 40 mm (1.6 in) in snout–vent length. The head is slightly wider than the body. The snout is rounded. The tympanum is distinct and round or slightly oval. The fingers and the toes have partial webbing, lateral fringes, and round terminal disks. The dorsum is pale brown with a dark, irregular pattern and fine white spots. There is a white spot under the eye. Males have a white vocal sac. A Gosner stage 27 tadpole measures 27 mm (1.1 in) in length, of which the tail makes two thirds.

Leptopelis mackayi is an arboreal species forest species found at elevations of 1,220 to 1,700 m (4,000 to 5,580 ft). Specimens have been located in both secondary forests and disturbed environments. One tadpole was identified within a puddle. Egg deposition is probably terrestrial, with the tadpoles wriggling themselves into puddles. This species is considered "vulnerable" because it is only known from two localities and because its habitat is believed to be declining in quality and quantity. It is present in the Kakamega Forest National Park.
