Jumping spiders, a striped gecko and a chirping frog are among more than 50 new species discovered in Papua-New Guinea, the environmental group Conservation International reported on Tuesday.

The creatures were found during an expedition in July and August in Papua-New Guinea's highlands wilderness, the group said in a statement.

A total of 50 spider species, two plants, three frogs and one gecko found on the expedition are believed to be new to science.

The three frogs include a tiny brown frog with a sharp chirping call, a bright green tree frog with big eyes and a torrent-dwelling frog that has a loud ringing call.
