  • 현호색과 현호색속 현호색절의 1신종인 각시현호색이 한국의 경기도 및 강원도에서 발견되어 기재되었다. 신종은 타원형 내지 선형의 소엽 형태, 전연 내지 선단이 약간 치아상인 탁엽 및 넓고 마름모형이 하측 외화판을 가지며, 또한 14개의 돌기가 있는 주두와 종자가 1열로 배열하는 선형의 삭과를 가짐으로써, 이와 가까운 유연관계가 있다고 판단되는 남도현호색과 뚜렷이 구별되었다.

  • A new species, Pythium subutonaiense, isolated from aquatic environments (lake) in China is being described based on morphological characters and molecular evidence. The isolates grew at temperatures between $5^{\circ}C$ and $38^{\circ}C$, and the optimum temperature was $30^{\circ}C$, with a radial growth rate of 17.6 mm at $25^{\circ}C$ per day. It is homothallic and characterized by globose to sub-globose shaped and mostly terminal or sometimes catenulate hyphal swellings, filamentous non-inflated sporangia, and smooth oogonia with hypogynous and monoclinous antheridia that contained one plerotic oospore. In phylogenetic analysis, inferred based on the internal transcribed spacer region of the ribosomal RNA gene and mitochondrial cytochrome c oxidase subunit 1 gene, the new species formed a distinct lineage in Pythium clade B. Differences between the new species and phylogenetically related and morphologically similar species are discussed.

  • Linyphiidae Blackwall, 1859 is one of the most diverse and largest families within the order Araneae Clerck, 1757. Of the currently 60 valid species of the genus Neriene Blackwall, 1833 worldwide, 10 species are distributed in Korea. The males of the new sheet-web spider Neriene bovista sp. nov. were recently collected with a sweep net between the shrubs of mixed forests from the hilly valley with well conserved nature in Uljin-gun, Gyeongsangbuk-do (the middle east coast region) during a seasonal survey of the spider fauna in hilly terrains in 2017-2018. The present study describes a new sheet-web spider, Neriene bovista sp. nov. with a diagnosis, detailed description, morphological illustrations, and a distribution map from Korea. The new species has a characteristic mushroom-like tip of the terminal apophysis, the truncated tip of anterior projection, and the bifurcated lateral projection of the lamella compared to the congeners of the genus Neriene Blackwall, 1833.

  • One new species of the genus Myrmica was found from Mt. Moak in Chonbuk, Korea. It was named as Myrmica cadusa n. sp. on the basis of external shape of the antennal socket, which is jar-shaped. Accordingly Korean Myrmica now includes 13 species in total.

  • A specimen of the unknown form of Octopus species was collected from Onsan, Kyungsangnam-do, eastern coast of Korea on 20th June 2004 with a bottom trawl. The specimen distinguished from the other Octopus species reported hitherto by its extremely short 2nd pair of arm and hectocotilization of the right 4th arm. It may be described, therefore, as new species, but only one specimen was collected unfortunately. A new name will be deferred, consequently, until more specimens will be available in the future.

  • Species selective spectroelectrochemistry (SSSE) is described by relating the derivative absorbance (dA/dt) signals with electrochemical currents for conventional transient electrochemical experiments. Expressions relating the currents with the dA/dt signals were obtained. From these expressions, physical constants such as coefficients and molar absorptivities of electrogenerated species can be determined. By obtaining both derivative absorbance and current signals concurrently and comparing them, one can perform the SSSE experiments. The utility of the SSSE in sorting out electrochemical information is demonstrated.
