A tiny frog species with a sharp chirping call believed to be new to science, Oreophryne, is pictured in this undated handout photo. The Oreophryne was discovered in limestone hills during a Conservation International (CI) led Rapid Assessment Program (RAP) expedition of Papua New Guinea's highlands wilderness in 2008. 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 March 24, 2009.[Agencies]
