A revised checklist of Korean Trichoptera is provided for the species recorded from the Korean Peninsula, including both North and South Korea. The checklist includes bibliographic research as well as results after reexamination of some specimens. For each species, we provide the taxonomic literature that examined Korean Trichoptera materials or mentioned significant taxonomic treatments regarding to Korean species. We also provide the records of unnamed species based on larval identification for further study. Based on taxonomic considerations, 20 species among the previously known nominal species in Korea are deleted or synonymized, and three species omitted from the previous lists, Hydropsyche athene Malicky and Chantaramongkol, 2000, H. simulata Mosely, 1942 and Helicopsyche coreana Mey, 1991 are newly added to the checklist. Hydropsyche formosana Ulmer, 1911 is recorded from the Korean Peninsula for the first time by the identification of Hydropsyche KD. In addition, we recognized 14 species of larvae separated with only tentative alphabetic designations. As a result, this new Korean Trichoptera checklist includes 218 currently recognized species in 66 genera and 25 families from the Korean Peninsula.

The Fucales plants have very homogenous taxonomic characteristics at order level, but show many morphological variatations at species or subspecies levels. This study is one of the serial works to obtain more taxonomic data than morphotaxonomic ones and to clarify the taxonomic ranks and characteristics of Korean Fucales plants through physiological and biochemical analyses. Total lipid compositions of Korean Fucales plants were analyzed by the 3-dimensional TLC method. Major components of phospholipids (PA, PC, PG, PE, DPG, LPE, LPC), neutral fat TG and sterols were commonly contained in each species. Unknown lipids X1, X2 and X3 were contained in genus Sargassum, but Hizikia was lacking X3 and Myagropsis was lacking both X2 and X3. The latter contained unique X8. From the view-point of the phylogeny of lipid metabolism, Sargassum might be more closely related to Hizikia than to Myagropsis. A variant of S. patens from Seongsan showed minute metabolic difference from that of the typical plant; but a variant of S. serratifolium did not show any significant difference from that of the typical plant.

The taxonomic study of the genus Myzia Mulsant, 1846 in Korea is presented. The genus Myzia contains five species worldwide and two species currently recognized in Palaearctic region. Until now, only M. oblongoguttata (Linnaeus, 1758) has been known in Korea, but we found M. gebleri (Crotch, 1874) for the first time in Korea. We redescribed these two Korean species of the genus Myzia with photographs of the habitus and detailed illustrations of their aedeagus and other appendages. A taxonomic key to the species of Korean Myzia beetles are also provided.

A systematic mosquito taxonomic study in Korea was established by Lee in 1971. Since then, many species have been recorded as new to Korea. However, much of this taxonomic information has been distributed in a number of scientific publications. This fork attempts to combine this information into a single document, as well as to synthesize revised taxonomic synonyms of species cccurring in Korea. Four species, Culex vora.x, Culex kangi, Aedes kobayashii and Culiseta kanayamensis listed in our previous paper, are synonyms of Culex kalifaxii, Cutex jackseni, Aedes alehtorowi and Culiseta bergrothi, respectively. Culex annulus is a misidentified species of Culex pseudovishnui. The subspecies Cutes pipiens quinquefassiatus and subgenus Manscnia (Ccquillettidia) were treated as full species and genus respectively in a catalog of the mosquitoes of the world. However, not all current authors agree to those specific and generic treatment. Based on available publications the total number of mosquito species recorded in Korea is now 52 representing 9 genera. Forty-five of these 52 are confirmed species with preserved specimen representation. As collection of specimen continues, there is a possibility that representative of 7 unconfirmed species will be found. 1 hope this paper will provide useful information for entomology workers who are interested in mosquito taxonomy in Korea.

Vicia bifolia Nakai (Fabaceae) and Cyperus compressus L. (Cyperaceae) have been ambiguous in terms of their distribution and taxonomic entities in Korea. The existence of these two taxa was confirmed when V. bifolia and C. compressus was found on Jellabuk-do, Gyeongsangnam-do, and Jeju-do. Vicia bifolia is similar to V. unijuga by having a pair of leaflets but is distinguished by the length of the petiole, the size and degree of longevity of the bracts, and the shape of the stipules. Cyperus compressus was found on Jeju-do, is similar to C. tenuispica, C. haspan, and C. flaccidus, but is distinguished by the branching pattern of the inflorescences and the size of scales and achenes. A description, differences from related species, a key to the taxa and photographs of Korean Vicia bifolia and Cyperus compressus are provided in this study.

The genus Gueldenstaedtia Fisch. is small genus of Fabaceae that includes four species worldwide. Among these, G. monophylla Fisch and G. verna (Georgi) Boriss. are currently recognized as occurring in Mongolia. Here, we present our findings on G. verna from our recent field surveys in eastern Mongolia in 2020. Gueldenstaedtia monophylla is mostly distributed in the western region, whereas G. verna occurs in eastern Mongolia. The regional conservation status of both species was assessed as near threatened based on criterion B in the country. We provided descriptions, grid distribution maps, taxonomic notes and photographic illustrations of the two species based on our newly collected samples.

Aconitum kaimaense Uyeki & Sakata was first collected by Uyeki & Sakata at Bujeon Plateau in Hamgyongnam-do and reported as a new species and recorded in Enumeration of Korean Plants (Pak, 1949). A. kaimaense was taxonomically treated under the name of Aconitum jaluense Kom in A Revision of Aconitun Subgenus Aconitum (Ranunculaceae) of East asia. (Kadota, 1987), and it was also treated as synonym in Korea(1996, 2007, 2011). A. kaimaense has erect or apically slightly curved stem, dense corymb inflorescence, pubescent pedicels, yellowish white sepals and carpels 5(or 4) pubescent. In this study, to investigate the taxonomic location of A. kaimaense, we conducted literature observation, sample observations in KYO, TNS, KH, SNU, SKK, and field research in Korea. The distribution in Hongcheon, Pyeongchang, Jeongseon, and Yangyang of Gangwon-do was confimed.

Large scale protein interaction maps provide a new, global perspective with which to analyse protein function. PSIMAP, the Protein Structural Interactome Map, is a database of all the structurally observed interactions between superfamilies of protein domains with known three-dimensional structure in thePDB. PSIMAP incorporates both functional and evolutionary information into a single network. It makes it possible to age protein domains in terms of taxonomic diversity, interaction and function. One consequence of it is to predict the most important protein domain structure in evolution. We present a global analysis of PSIMAP using several distinct network measures relating to centrality, interactivity, fault-tolerance, and taxonomic diversity. We found the following results: ${\bullet}$ Centrality: we show that the center and barycenter of PSIMAP do not coincide, and that the superfamilies forming the barycenter relate to very general functions, while those constituting the center relate to enzymatic activity. ${\bullet}$ Interactivity: we identify the P-loop and immunoglobulin superfamilies as the most highly interactive. We successfully use connectivity and cluster index, which characterise the connectivity of a superfamily's neighbourhood, to discover superfamilies of complex I and II. This is particularly significant as the structure of complex I is not yet solved. ${\bullet}$ Taxonomic diversity: we found that highly interactive superfamilies are in general taxonomically very diverse and are thus amongst the oldest. This led to the prediction of the oldest and most important protein domain in evolution of lift. ${\bullet}$ Fault-tolerance: we found that the network is very robust as for the majority of superfamilies removal from the network will not break up the network. Overall, we can single out the P-loop containing nucleotide triphosphate hydrolases superfamily as it is the most highly connected and has the highest taxonomic diversity. In addition, this superfamily has the highest interaction rank, is the barycenter of the network (it has the shortest average path to every other superfamily in the network), and is an articulation vertex, whose removal will disconnect the network. More generally, we conclude that the graph-theoretic and taxonomic analysis of PSIMAP is an important step towards the understanding of protein function and could be an important tool for tracing the evolution of life at the molecular level.

Goodyera rosulacea, which is morphologically similar to G. repens, is described recently as a new species based on its distinct morphological characters such as rosette-formed leaves, short rhizome and habitat. To verify the taxonomic identity of G. rosulacea and its taxonomic relationship within Korean Goodyera taxa, sequences of the internal transcribed spacer (ITS) region of nuclear ribosomal DNA and the trnL region of cpDNA from 24 accessions including 1 outgroup accession were analyzed. Aligned sequences were analyzed using maximum parsimony and distance method, and the taxonomic identity and the taxonomic relationships among the related taxa were estimated by the existence of private marker gene and the phylogenetic tree of the aligned sequences. Molecular data indicate that G. rosulacea gas several private marker genes and shows monophyly in phylogenetic trees of both ITS and trnL sequences. the pairwise distance between G. rosulacea and the orher taxa of Korean Goodyera was 3.49-6.68% for ITS region and 5.05-9.53% for trnL region, indicating that G. rosulacea could be treated as an independent species. Therefore, our molecular data support the taxonomic of G. rosulacea as a distinct species of Korea. In phylogenetic trees, G. rosulacea formed same clade with G. repens, which has similar morphological characters with G. rosulacea, and showed the lowest pairwise distance with G. repens among Korean Goodyera taxa. These molecular data sugguested that G. rosulacea and G. repens are closely related taxa.
