Sphenophryne cornuta is a species of frogs in the family Microhylidae. It is endemic to New Guinea where it is widespread and found both in the Western New Guinea (Indonesia) and Papua New Guinea. Common name horned land frog has been proposed for it.
Adult males measure 28mm37mm and females 29mm42mm in snout–vent length. Each eyelid bears a small but distinct, pointed tubercle, making this species easy to recognize. The fingers have enlarged discs that are larger than those on the toes. The loreal region is flat and vertical, distinct from the flat upper surface of the pointed snout.
Sphenophryne cornuta breeds by direct development, and the male carries its babies on its back.
Sphenophryne cornuta inhabits tropical rainforests at elevations below 1500m (4,900feet). It hides in leaf litter and under logs during the day, and calls from bushes and saplings in understorey at night. It also lives in disturbed habitats including gardens and degraded forests.
Sphenophryne cornuta is a common and very widespread species. It faces no known threats.
