A new limnephilid caddisfly, Nothopsyche bilobata n. sp., is described. The female adult of Apatania martima Ivanov and Levanidova and the larva of Ecclisomyia kamtshatica (Martynov) is newly recorded from Korea. Three undetermined species, Nemotaulius sp. A, Nemotaulius sp. B, and Nothopsyche sp. A, are additionally described.

A new goerid caddisfly, Goera jaewoni n. sp. (Trichoptera: Goeridae), is described from Korea. Larval stages of G. interrogationis Botosaneanu and G. parvula Martynov are also reported for the first time based on reared specimens. Line-drawings of the key characters and taxonomic and ecological notes are provided.

An examination of caddisfly materials from the field trips in Vietnam during 2002-2003 resulted in the recognition of the male adult of Tinodes reuse Malicky & Chantaramongkol(new Vietnamese record) and four undetermined species of larvae (Psychomyia VL1, Psychomyia VL2, Paduniella VL1, and Tinodes VL1) in the family Psychomyiidae Genera Psychomyia and Paduniella are recorded from Vietnam for the first time. Material data, descriptions, diagnoses, distributions, and taxonomic remarks are provided.

The specimens of caddisflies previously recorded as Sortosa distincta (Walker, 1852), Rhyacophila uchidai Kobayashi, 1989, Rhyacophila jirisana Kobayashi, 1989, Crunobiodes koriaensis Kobayashi, 1989, and Ganonema odaenum Kobayashi, 1989 from South Korea were reexamined. Rhyacophila uchidai and R. jirisana are newly synonymized with R. retracta Martynov, 1914 and R. vicina Botosaneanu, 1970, respectively. We reconfirm two synonyms, C. koriaensis with Lepidostoma sinuatum (Martynov, 1935) and G. odaenum with Psilotreta locumtenens Botosaneanu, 1970, and a misidentification of Dolophilodes affinis Levanidova and Arefina, 1996 as S. distincta. Some specimens recorded as G. odaenum are identified as Psilotreta falcula Botosaneanu, 1970.

This study was conducted to estimate the habitat suitability of 17 benthic macroinvertebrate taxa in the Hwayang stream. Habitat Suitability Index (HSI) of benthic macroinvertebrates from the Hwayang stream was developed based on three physical habitat factors which include current velocity, water depth, and the substrate. The Weibull model was used as a probability density function to analyze the distribution of individual abundance by physical factors. The number of species and the total individual abundance increased along with the increase in current velocity. By means of Canonical Correspondence Analysis (CCA), the relative importance of each factor was determined in the following order: current velocity, water depth, and the mean diameter. The results depicted that, the most influential factor in the growth of benthic macroinvertebrates in the Hwavang system was current velocity. After comparing the analyzed results from the Hwayang stream with the resukts from the Gapyeong stream, the integrated HSI was drawn. The results indicated that current velocity and substrate had similar distributions of HSI in the two streams. This was due to the addition of unmeasured data from previous surveys, or the fact that benthic macroinvertebrates adapted to deeper waters in the Hwayang Stream. Most taxa showed a clear preference for a fast current velocity, deep water depth and coarse substrate except Baetiella, Epeorus, (mayflies), and Hydropsyche (caddisfly).

Habitat suitability index (HSI) of 17 benthic macroinvertebrate taxa, which were lotic insects of generic category except Potamanthidae in mayfly, was developed for three physical habitat factors (current velocity, water depth and substrate) based on an ecological monitoring in a Korean stream (Gapyeong). Weibull model was used as a probability density function to analyze the distribution of individual abundance related with physical factors, which showed it was so available. Number of species and total individual abundance increased along with the increase of current velocity and the mean diameter of substrate, and decreased along with the increase of water depth. Most taxa showed a clear preference for a fast current velocity, shallow water depth and coarse substrate except Ephemera, Potamanthidae (mayfly), and Plectrocnemia (caddisfly) which were rheophobic, potamophilic and lithophobious. Based on the canonical correspondence analysis, the relative importance of each factor was determined as follows: current velocity > substrate > water depth.

Colonization patterns and community changes in benthic macroinvertebrates in the Cheonggye Stream, a functionally restored stream in downtown Seoul, Korea, were studied from November 2005 to November 2007. Benthic macroinvertebrates were quantitatively sampled 15 times from five sites in the stream section. Taxa richness (59 species in total) increased gradually over the first year, whereas the density revealed seasonal differences with significantly lower values in the winter season and after flood events. The benthic macroinvertebrate fauna may have drifted from the upstream reaches during floods and from the Han River, arrived aerially, or hitchhiked on artificially planted aquatic plants. Oligochaeta, Chironommidae, Psychodidae, and Hydropsychidae were identified as major community structure contributors in the stream. Swimmers and clingers colonized relatively earlier in the upper and middle reaches, whereas burrowers dominated particularly in the lower reaches. Collector-gatherers colonized at a relatively early period throughout the stream reaches, and collector-filterers, such as the net-spinning caddisfly (Cheumatopyche brevilineata), predominated in the upper and middle reaches after a 1-year time period. Cluster analyses and multi-response permutation procedures demonstrated that the Cheonggye Stream shares more similarities with the Jungnang Stream than with the Gapyeong Stream. Detrended correspondence analysis and nonmetric multidimensional scaling demonstrated that physical environmental factors (depth, current velocity, dissolved oxygen, and pH) as well as nutrients (total nitrogen and total phosphorous), water temperature, and conductivity could affect the distribution of benthic macroinvertebrates in the study streams.

Since a large bank-protection works project was undertaken during winter in the middle reaches of the Chikuma, the riverbed structure was drastically altered. In order to assess the short-term impact of bank-protection works on the abundance Pattern of Stenopsyche marmorata (Trichoptera) from spring to early summer, we conducted an investigation on the capture of adults using light traps before and after construction work. The patterns of the daily capture of S. marmorata and the Namely, after construction, the daily catch of adult numbers increased only slightly during the investigation periods. This suggested that the age structure of the S. marmorata larval population had changed in the construction area. Our data suggest that bank-protection projects impact the abundance pattern of adult caddisflies in the river ecosystem.
