Solomon Island Palm Frog

Cornufer heffernani has a small, delicate, slender body and limbs. A syntype specimen of Hylella solomonis in the Senckenberg Museum measures 28 mm (1.1 in) in snout–vent length. The head is broader than the body and triangular in shape. The snout is broadly rounded and the eyes are large. The canthus rostralis and the tympanum are indistinct. The limbs are slender. Both the fingers and the toes are webbed and bear well-developed discs. Skin is smooth above but granular on the flanks, the belly, and under surface of the upper arm and thighs. Preserved specimens are purplish brown above and yellow below, fading to yellowish all over with time.

Cornufer heffernani is a very rare species that is found on low vegetation and trees in tropical rain forests. It can also be found in good-quality secondary forests. It has direct development, that is, it breeds without free-living tadpole stage. It is threatened by habitat loss caused by logging.
