Lamellicorn beetles (coleoptera: Scarabaeoidea) in korea and mongolia

This work was undertaken as an initial part of the collaborative effort between Korean and Mongolian researchers to study the terrestrial and aquatic insects in these countries. An analysis of data on faunal composition, taxonomic diversity and biogeographical structure of lamellicorn beetles in Korea and Mongolia was conducted in order to characterize the faunal relations between two countries. The Korean fauna of lamellicorn beetles is almost two fold greater in both generic diversity and species richness than that of Mongolia. The species compositions of lamellicorn beetles in two countries are substantially different from each other and the relative levels of faunal overlap are insignificant. Not only the faunal diversity and composition, but also the biogeographical structure of lamellicorn beetles in Korea and Mongolia display dissimilar patterns, except for their similar degree of endemism. Additional data on communities of dung beetles in the grasslands of central Mongolia, as well as a brief discussion on conservation issues of the endangered species in Korea, especially Gymnopleurus mopsus, are given.
