Review of the Korean Elmidae (Coleoptera: Dryopoidea) with descriptions of three new species

Abstract

The Korean species of the riffle beetle family Elmidae are revised. Thirteen species belonging to nine genera are recognized including three new species, Grouvellinus aerosus sp. n., Zaitzeviaria kyungseoki sp. n., and Z. obesa sp. n., and one unidentified species of Ordobrevia Sanderson, 1953. Leptelmis coreana Jung and Bae, 2012 and L. ochra Jung and Bae, 2012 are synonymized with L. gracilis gracilis Sharp, 1888. Four species, Macronychus levanidovae Lafer, 1980, Stenelmis koreana Sato, 1978, S. cf. montana Zhang and Yang, 1995, and Zaitzevia tsushimana Nomura, 1963, are newly recorded from South Korea. Descriptions, type information, synonymies, illustrations of diagnostic characters and geographical variation, a checklist, and a key to the adults of the Korean species are provided. http://zoobank.org/urn:lsid:zoobank.org:pub:738109DF-D49D-4398-96B2-FC5863ED76EF
