Two species of the chloroperlid stonefly, Alloperla medlata and Sweltsa illiesi, are reported for the first time in Korea. Alloperla mediata can be distinguished by the smaller epiproct and the presence of a median sclerite under epiproct in male, and by the modified subgenital plate in female. Sweltsa illiesi can be distinguished by the presence of a pair of ridges on tergum 9 in male and upward V-shaped pattern on the center of head in adults. The line drawings of diagnostic characters and taxonomic remarks of the two species are provided with keys and comparative characters for adults of Korean Chloroperlidae.

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.

A new and rare perlid stonefly, Togoperla thinhi n. sp., is described from male and female adults and egg specimens from tropical central Vietnam. The male adult of T. thinhi n. sp. can be distinguished from other congeners by the distinct head markings, bilobed processes on the posterior margin of the abdominal tergum V, and S-shaped aedeagus. The female adult has a long and tongue-shaped subgenital plate on the abdominal sternum VIII, which extends to the posterior margin of the abdominal sternum IX. A male key to the Vietnamese species of Togoperla is provided. The finding of this new species provides evidence of an extension of the geographical distribution of Togoperla to tropical mainland Southeast Asia.

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).

To reveal the feeding ecology of Rhynchocypris semotilus, the survey was conducted in Songhyeoncheon, Songhyeon-ri, Hyeonnae-myeon, Goseong-gun, Gangwon-do in April 2022. As a result of analyzing the contents of the stomach using the index of relative importance (IRI), the important prey organisms were mainly Trichoptera (46.6%), Ephemeroptera (27.6%), Diptera (12.6%), Odonata (9.7%), Plecoptera (2.8%), Coleoptera (0.6%), and Hemiptera (0.1%) of Class Insecta, Phylum Arthropoda in that order. As a result of analyzing the trend by calculating the index of relative importance (IRI) for each age, it was found that those born in the same year mainly feed on relatively small Ephemeroptera and Diptera, but the proportion of these gradually decreases as they grow. And the proportion of relatively large Trichoptera and Odonata gradually increased, turning them into the most important food source for those over 3 years old. Additionally, prey size was the smallest at 2.8±2.5 (0.6 to 9.0) mm for individuals born in the same year, but gradually increased to 5.1±6.1 (1.1 to 17.0) mm for individuals born more than 3 years. As a result of examining prey selectivity, Plecoptera (+0.78), Trichoptera (+0.66), (+0.66), Coleoptera (+0.66), and Hemiptera (+0.03) showed positive selectivity, while Amphipoda (-1.00), Ephemeroptera (-0.24), Odonata (-0.13) and Diptera (-0.05) showed negative selectivity.

Analysis of benthic macroinvertebrate community and biological estimation of water quality was conducted at the national park of Mt. Jiri and its nearby area in Gurye, Sancheong and Hadong-gun from June to November, 2002. Total taxa of benthic macroinvertebrates were 124 species, 45 families, 15 orders, 5 classes in 3 phyla. Aquatic insects were 33 species in ephemeroptera, 28 species in Trichoptera, 21 species in plecoptera, 13 species in Diptera, 8 species in odonata, 5 species in hemiptera and 5 species in coleoptera, respectively. Non-insects were 5 species in Mollusca, 2 species in Hirudinea, 1 species in oligochaeta and 1 species in crustacea, respectively. Ephemeroptera, trichoptera and plecoptera as indicators in clean water were very abundant. Occurrence species at each survey area was 68 species at Mt. 1025-goji, 59 species at Mt. Eungseok-bong, 57 species at Mt. Wangdeung-jae, 50 species at Mt. Cheonwang-bong and 39 species at Mt. 645-goji, respectively. Mean species diversity indices at Mt. Cheonwang-bong, Mt. 1025-goji, Mt. Wangdeung-jae, Mt. Eungseok-bong and Mt. 645-goji were 3.33, 3.03, 3.41, 3.02 and 2.91, respectively, According to the saprobic system based on the species diversity indices of benthic macroinvertebrates, most survey areas except some sites are determined as Limnosaprobic area.
