ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICT Tomus 65. Budapest 1973. Plecoptera from Korea* By P. ZWICK, Schlitz (BRD) Abstract — 14 Plecopteran species from N. Korea are discussed; of these 7 taxa are new, Amphineura coreana sp. n., A. steinmanni sp. n., A. verrucosa sp. n., Nemoura sahlbergi problematica ssp. n., Rhopalopsole mahunkai sp. n., Alloperla picta sp. n., and Schistoperla decorata sp. n. In the course of the First Expedition of the Hungarian Natural History Museum to Korea in 1970 (participants: Dr. S. MAHTJNKA and Dr. H. STEINMANN) a number of Plecoptera have been taken and were kindly submitted to me for study. The present paper is a systematic treatment of this material. General reports on the expedition have already been given by STEINMANN & MAHTJNKA (1971) and MAHTJNKA & STEINMANN (1971) serial; numbers in the lists of material (below) refer to a list of localities and collections in the latter paper. I have also had an opportunity to study additional material from the collections of the Zoological Museum PAN, Warszava, the results being exposed in a second paper (ZWICK 1973b). This second paper also contains a review of the few previous records of stoneflies from Korea. NEMOURIDAE Amphinemura coreana sp. n. (Figs. 1-5) Holotype rf , paratypes 2 cTd* 4 Ç Ç Korea, Prov.
