  • 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.

  • Ten Korean eumenine wasp species of the genus Stenodynerus, including one new species and six newly recorded species (Stenodynerus chinensis simillimus, S. coreanus, S. clypeopictus, S. funebris, S. frauenfeldi, S. Kalinowskii, S. pappi, S. pullus, S. tergitus sp. nov., S. tokyanus) from Korea were taxonomically reviewed. The male of S. pappi was collected for the first time. Additional characters to distinguish several congeners were also discussed.

  • Pseudanthessius spinosus n. sp. is described as an associate of the sea urchin Clypeaster japonicus Doderlein from Cheju Island in Korea. The new species may be easily distinguished from its congeners by having four spines and five setae on the third exopodal segment of leg 4. It is the second known species of the genus from Korean waters.

  • PCBs are wide spread persistent environmental pollutants that exert a broad spectrum of toxic effects. PCBs includes 209 possible congeners differing in extent and position of chlorination of their aromatic rings. In order to understand the toxic mechanism of PCBs, we have tested the effect of PCB on the EROD activity in vivo.(omitted)

  • A series of new direct dyes based on benzidine congeners, 2,2'-dimethyl-5,5'-dipropoxybenzidine and 5,5'-dipropoxybenzidine, were evaluated for mutagenicity in Salmonella typhimurium strains TA98 and TA100. All of the dyes examined were judged to be non-mutagenic with and without metabolic activation while toxicity was seen in some dyes at high doses. The study also suggested that the standard Salmonella mutagenicity plate-incorporated assay was an excellent method for evaluation of direct dyes for mutagenicity.

  • A new species of the cave-dwelling springtail Lethemurus coreanus Chang and Bae, sp. n. is described from Korea. Lethemurus coreanus can be distinguished from congeners by the spine-like setae on the tibiotarsus, numbers of dental spines, number of setae on the trochanteral organ, and body macrochaetae chaetotaxy. A key to the species of Lethemurus is provided.

  • Paradexamine jindoensis n. sp. belonging to family Dexaminidae was collected from Jindo Island, Korea. The new species is fully illustrated and compared with related congeners. The new species resembles highly P. houtete, in having the tooth formulae of dorsal pleonites, 1-3-3-3, rear to front and in bearing short spines on the mandible. However, it is characteristic in having the several morphological differences of mouth parts, slender appendages, and longer peduncular article 2 of antenna 1 than article 1.
