Cornufer guppyi (common name: giant webbed frog or Shortland Island webbed frog) is a species of frog in the family Ceratobatrachidae.[3] It is named after Henry B. Guppy who collected the holotype from the Shortland Islands.[2][4] It is found in New Britain Island (Papua New Guinea) and in the Solomon Islands archipelago, where it is widespread, though it is missing from Makira island (=San Cristobal).[3]

Cornufer guppyi is the type species and the sole representative of the subgenus Discodeles (formerly recognized as a genus).[5]


Cornufer guppyi are large frogs: females can be as large as 250 mm (9.8 in) in snout–vent length and weigh 1 kg (2.2 lb).[5] Females up to 60 mm (2.4 in) may still not be mature. The snout is rounded. The tympanum is round.[6] The fingers and toes have moderately expanded terminal discs. The toes are fully webbed.[5] The legs are long. Males have external vocal sacs.[7] Preserved specimens show variable colouration, from light tan/almost white to greyish to dark reddish brown, with various darker brown or blackish brown marbling or blotching. The venter is light tan or whitish, often with some brown blotches or speckles.[6]

Habitat and conservation[edit]

Cornufer guppyi is a common species. It inhabits streams and small rivers in lowland rainforests up to elevations of 700 m (2,300 ft) above sea level. It also tolerates some habitat degradation and can be found in rural gardens and degraded forests. It is also known from caves. It can be locally impacted by habitat loss caused by logging, and by collection for human consumption and pet trade.[1]
