  • Nemoura phasianusa n. sp. is similar to Nemoura jezoensis in general morphology especially lateral view, but can be distinguished by the combination of the characters of the epiproctal shape whose apex is depressed medially, and sclerites of epiproct, which look like question marks without dots.

  • Four new nemourid species, Amphinemura rai n. sp., Amphinemura baei n. sp., Protonemura villosa n. sp., and Nemoura espera n. sp. are described and illustrated. Amphinemura rai n. sp. closely resembles Amphinemura tragula (Kimmins) externally, but differs from Amphinemura tragula by the projections on male terminalia and the shape of the female subgenital plate. Amphinemura baei n. sp. is similar to A. bulla Shimizu in body color, size, and structure of male and female terminalia, but distinguished by the ventral sclerites of epiproct, the knobs on the sides of the epiproct, and the shape of paraprocts. Protonemura villosa n. sp. is similar to p. hotakana Ueno in body color, size, and the structure of terminalia, but distinguished by the epiproctal flagellum and ventral sclerite, the shape of the tenth tergum. Finally, Nemoura espera n.sp. is close to Nemoura alabeli Zhilt-zova In appearance, but differs by the shape and location of the ventral and dorsal sclerites of the epiproct.

  • Korean Plecopteran research was started in 1921, and it has advanced greatly during last 20 years. Among families the family Nemouridae and Chloroperlidae are composed of plentiful species. Since North Korean Plecopteran research was begun in 1938, it made good progress by foreigners not North Korean in the 1970's. Subsequently a few species has been added up recently, and among families the family Perlidae and Nemouridae contain most abundant species. Totally Korean Plecoptera consists of 43 species in 25 genera in 10 families, and North Korean 37 species in 26 genera in 10 families. Among them 13 species are common in both. And Korean names of Plecopteran species were mixed in Hangeul-type and Chinese-type, on the other hand in North Korean names there were some cases of Hangeul-type, but most of species have no Korean names. In Korea, particularly Ministry of Environment designated and controlled domestic biological resources as Korean Species that Require Approval when shipping abroad and Korean endemic species, which include 9 species and 11 species in Plecoptera respectively. Finally two genera and four species gained new Korean names as follows: genus Megaleuctra (Keun-Kkoma-Gang-Do-Rae-Sok), genus Haploperla (Han-Nok-Saek-Gang-Do-Rae-Sok), Nemoura brevicercia (Min-Gang-Do-Rae), Nemoura espera (Kkot-Min-Gang-Do-Rae), Amphinemura baei (Je-Ju-A-Ga-Mi-Min-GangDo-Rae) and Amphinemura rai (A-Ga-Mi-Min-Gang-Do-Rae).

  • A new species of the genus Nemoura is described from Korea. Nemoura gemma sp. n. is close to Nemoura jezoensis Okamoto and Nemoura alaica Zhiltzova, but can be distinguished by the entire shape, dorsal sclerite, and the presence of spines on ventral sclerite of epiproct, and the existence of cercal hooks.

  • Macroinvertebrates from a first order stream at Mt Jumbong, Kangwon-do, was examined for their abundance and biomass. Sampling was done by using a pipe sampler (${\phi}$ 20 cm) for 11occasions (n = 5) at 4${\sim}$6 weeks intervals during November 1997 through October 1998. Water temperature and electronic conductivity of the study stream ranged $0\;{\sim}\;14^{\circ}C$ and 15${\sim}$25 ${\mu}s$/cm, respectively. During the study, 53 insect taxa and 3 non-insect taxa were collected. Annual mean number of individuals (${\pm}$1 SD) was 77741${\pm}$69232${\cdot}$m$^{-2}$ ${\cdot}$yr$^{-1}$, being high in winter (${\pm}$1 SD) (December: 171178${\pm}$130468 $m^{-2}$) and low in summer (${\pm}$ 1 SD) (June: 29872${\pm}$13078 $m^{-2}$). Non-predatory subfamilies of Chironomidae and Nemoura sp. occupied 53.3% and 21.8% of annual abundance. Annual mean biomass was 10g${\cdot}$m$^{-2}$${\cdot}$yr$^{-1}$ in ash free dry weight (AFDW), being high in late winter (February: 16 gAFDW $m^{-2}$.) and low in summer (June: 3 gAFDW $m^{-2}$). Gammarus sp. represented 39.8% of the total biomass and was followed by non-predatory subfamilies of Chironomidae (15.2%) and Hydatohylax sp. (8.5%, Limnephilidae: Trichoptera). Since the non-predatory subfamilies of chironomidae were composed of many species, Nemoura sp. was the most abundant taxon. However, Cammarus sp. was surely the most important taxon to the functional aspects of this first order stream ecosystems.
