A research project entitled “Discovery of Korean Indigenous Species” was launched in 2006, and has been carried on as a continuous project until now. The main purpose of this project is to find undiscovered species on the Korean peninsula and ultimately register these species in the “National List of Species of Korea”. In this paper, we present 79 unrecorded species of the Korean metazoans. All species were obtained from the final reports of “Discovery of Korean Indigenous Species” which were performed during the first five years of the project, 2006 to 2010.
