  • 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.

  • A taxonomic study on three families of Plecoptera in Korea was performed with adults, nymphs and eggs. As a result, the identified species were eight species , eight genera. Among them, three species, Perlodes stigmata n.sp., Kamimura coreana n. sp. and Neoperla coreensis n.sp ., are described as new in this paper.

  • 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.

  • The feeding ecology of endangered Cottus hangiongensis was studied in the Hosan stream from September 2006 to August 2007 by collecting them seasonally. The stomach contents of C. hangiongensis consisted mainly of aquatic insects and Nematoda, small fish, fish eggs, snails (Semisulcospira libertina), and small stones were also observed. The main aquatic insects in the order of relative importance were Diptera, Trichoptera, Ephemeroptera and Plecoptera. The most important prey items were Chironomidae sp.1 and Hydropsyche kozhantschikovi. Change in the main prey organisms by season were Trichoptera in the spring and the summer, Diptera in the autumn, and Plecoptera in the winter by ratio of dry weight.

  • 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.

  • Egg incubation periods of 14 species of plecoptera were examined at $10^{\circ}\;{\sim}\;11^{\circ}C$, $15^{\circ}\;{\sim}\;16^{\circ}C$, $20^{\circ}C$, and $23^{\circ}C$ under dark conditions. The total effective temperature (TET) was calculated by multiplying mean egg incubation days and water temperature of incubation periods. The relation between the TET and the incubation temperature was used to compare the life cycle of respective species. Perlodid species had higher TET values with a positive relation to incubation temperature than those of other species. Perlid species had low TET values in the 14 species with negative to variable relation, and Chloroperlid species showed variable to positive relations to incubation temperature. These results suggest that the relation between the TET and the water temperature reflected on their habitat of respective species.

  • A new perlid stonefly, Chinoperla rhododendrona n. sp., is described from a tropical mountain stream in central Vietnam. The male adult of this species can be characterized by the strongly setous body and unique L-shaped genital structure. The female adult can be distinguished by the posteromedially sclerotized and widely notched subgenital plate. The egg is unique among its congeners as it has smooth chorion and long and narrow collar. Illustrations of diagnostic characters are provided.

  • 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.
