[1][2] The specific name keithae honors Rolanda Keith, an American herpetologist.

[4] Phlyctimantis keithae are medium-sized tree frogs: adult males measure 39–43 mm (1.5–1.7 in) in snout–vent length.

[5] Phlyctimantis keithae can assume a defensive posture where the frog rapidly twists onto its back and throws its limbs across the body.

This makes it look very little frog-like, and probably serves as camouflage, perhaps conflicting with the potential predator's search image.

Breeding takes place in shallow pools (including artificial ponds) with emergent vegetation.
