Conrad is confident new invertebrate species will be discovered in the uplands, and says the next surveys will focus on insects, spiders and snails.

The Cape Melville shade skink (Saproscincus saltus sp. nov.) rounds out the recent discoveries.

The team also discovered this blotched boulder-frog (Cophxalus petrophilus sp. nov.) in the isolated rainforests of Cape Melville.

The leaf-tailed gecko was discovered by a team led by Dr Conrad Hoskin, a biologist at James Cook University in Townsville.

This new leaf-tailed gecko (Saltuarius eximius sp. nov.) was among the three new species discovered at Cape Melville in March this year.

The uplands at Cape Melville are home to a unique rainforest habitat that has been isolated for millennia.

Cape Melville is a boulder-strewn mountain range on the east side of Cape York Peninsula, about 475km north-west of Cairns.
