  • Aquatic insects were collected from 18 sites in the Yongsan River System from August, 1988 to July, 1989. The monthly fluctuation and distributional pattern of the aquatic insects along the environmental factors were investigated. Quantitatively collected aquatic insects were identified, and numbers, standing biomass, dominance indices and diversity indices in each site and month were determined. The aquatic insect faun of the Yongsan River System was composed of 146 species, 82 genera, 38 families in 7 orders including 44 species of mayflies, 32 species of caddisflies, 24 species of stoneflies, 21 species of flies, 16 species of beetles, 6 species of dragonflies and 3 species of dobsonflies. Seasonal occurrence of species were more diversified in winter and spring than in summer. Also, the number of individuals occurred was higher in winter and spring than in summer while it was the highest in upper stream and the lowest in Kwang-ju stream. Component ratio of the number of individuals according to the insect orders was as follows: Mayflies 38.71%, Flies 36.97%, Stoneflies 10.21%, Caddisflies 6.80%, Beetles 2.96%, Dobbsonflies 2.74%, Dragonflies 0.95%. Percentage of standing biomass according to insect orders were as follows: Mayfiles 32.81%, Stoneflies 26.51%, Caddisflies 17.58%, Dobbsonflies 14.84%, Flies 3.74%, Beetles 3.08%, Dragonflies 1.45%, The highest standing biomass occurred in spring and the lowest in summer.

  • A revised checklist of the Korean Plecoptera is updated here, with 10 families, 36 genera, and 95 species are reported. Pictetiella asiatica Zwick & Levanidova, Claassenia radiata (Klapálek), Xanthoneuria unimaculata (Zhiltzova) and Sweltsa sp. Ko (temporary name) are known only from the Democratic People's Republic of Korea. Nemoura sahlbergi Morton, Perlomyia kiritshenkoi Zhiltzova, and Neoperla adamantea Murányi & Li are reported for the Republic of Korea in this study. Nemoura ussuriensis Zhiltzova, Capnia sidimiensis Zhiltzova, Eucapnopsis quattuorsegmentata Okamoto, Yoraperla uenoi (Kohno), Isoperla kozlovi Zhiltzova, and Kamimuria lyubaretzi Teslenko are new from the Korean peninsula. Materials, bibliographic data, diagnoses for newly recorded species, and their distributions are provided.

  • Comprehensive bibliographic sources of Plecoptera systematics in Korea and Far East Russia were provided. Systematic status and distributional features of stoneflies in those areas were also discussed. Based on comprehensive type and non-type material examinations in those areas, new synonymies of Sweltsa colorata Zhiltzova and Levanidova, 1978 〔= Sweltsa nikkoensis (Okamoto), 1912〕 and Capnia KUa (Yoon and Aw, 1986)〔=Paracapnia recta Zhiltzova, 1984〕 were established; and the following species were newly recorded from Korea: Taenionema aponicum (Okamoto), Paraleuctra cercia (Okamoto), Leuctra fusca (Linnaeus), Eucapnopsis stigmatica Okamoto, Paracapniarecta Zhiltzova, Nemoura jezoensis (Okamoto), Stavsolus japonicus (Okamoto), Isoperla flavescens Zhiltzova and Potikha, Alloperla joosti Zwick, A. rostellata (Klapalek) Sweltsa nikkoensis (Okamoto), and S. lepnevae Zhiltzova.

  • A large number of stonefly nymph fossils were discovered from the Late Triassic Amisan Formation in the Boryeong region, Korea. These Plecoptera were classified as Platyperlidae, Baleyopterygidae, and Siberioperlidae based on their external morphologies. The Baleyopterygidae were most abundant among the fossils. This suggests that the plecopteran has already been widely distributed in the Northeast Asian region including Russia, Mongolia and China during the Mesozoic. The fossils of these stoneflies imply that benthic habitats of flowing and fresh waters may have existed, given the fact that they are similar with the biology of extant species. These Plecoptera were found together with Ephemeroptera and Conchostraca and thus, they were presumed to be preying on these insects.
