Lynceid conchostracans of the order Laevicaudata in East Asia are reviewed. Validity of the three older species, Lynceus mandsuricus Daday, Lynceus biformis (Ishikawa), and Lynceus dauricus Thiele, is examined and discussed. Two species among them were acknowledged but L. dauricus was synonymized to L. biformis and redescribed and illustrated in the present paper, based on the materials collected from the rice-fields at 15 localities in Korea.

Objectives : Herbal medicines have been used a lot traditionally in Northeast Asia. In particular, various Apiaceae plants (Umbelliferae) are widely used for medicinal purposes among countries. However, the original species designated in each pharmacopoeia standards, are sometimes different and confuse. In this study, herbal medicines in the pharmacopoeia were analyzed for Apiaceae taxa to compare the taxonomic identity and different taxonomic opinions for each country based on their local flora and recent taxonomic studies. Methods : The scientific names of herbal medicines were analyzed origins from Pharmacopoeias of Republic of Korea, Democratic People's Republic of Korea, People's Republic of China, Taiwan, and Japan. Especially, we compared their local floras, international plant scientific name database, and recently published taxonomic studies to confirm the correct scientific name. Results : The analyzed apiaceous herbal medicines in pharmacopoeias were all 21 items and 39 taxa; the highest percentage, genus Angelica (21%) and roots including rhizomes (62%) the registered genera and medicinal parts, respectively. Eleven items were in all five country's pharmacopoeias. Four items were in more than two countries' pharmacopoeias. Six items were registered in only one pharmacopoeia. Conclusions : Our research provides necessary information, e.g., corrected scientific names of original species based on taxonomic species concepts, taxonomic reviews, and figures of medicines. These results will help in the understanding of the apiaceous taxa among the five countries' pharmacopoeias. Moreover, these extensive nomenclatural reviews of authentic apiaceous taxa will help for the next revision of Korea Pharmacopoeia.

Taxonomic confusion has been presented within freshwater crayfishes of the genus Cambaroides since Starobogatov published morphological definition and revision of the group in 1995. He suggested that Cambaroides should be revised: the C. dauricus, contained three species C. dauricus, C. wladiwostokiensis, and C. koshewnikowi; the C. schrenckii with two. species C. schrenckii and C. sachalinensis. Also Straovogatov did not take into account the previous data. of crayfish distributions. In order to. clear up the confusion, the taxonomy of crayfish sampled from Mongolia, Russia, China, and North Korea was reassessed. Starovogatov's key could not lead to the correct identification. Also, detailed observations of apical robe of the male first pleopod did not support the taxonomy on the genus Cambaroides proposed by Starobogatov in 1995. However, some local variations of morphology exist in rostrum, pleuron, and telson of Asian crayfish. Future studies should be concentrated on whether there are geographical clines of morphology or if taxonomic subdivision is necessary.

We investigated the taxonomic status of the Korean populations of Eurema hecabe (Linnaeus, 1758) based on morphology and nuclear triose phosphate isomerase (Tpi). Up to now, the Korean population of E. hecabe was classified into E. mandarina (de l'Orza, 1869) based on morphological characteristics. A previous study raised the possibility of the Jeju-do population to be E. hecabe based on the color of forewing's fringe. However, morphological examination showed that the Korean population found in southern areas (Gyeonsang and Jeolla provinces), including Jeju-do is E. mandarina. In particular, the external morphology of autumn seasonal type of the Korean population was almost same as the Japanese mainland population, which is known as E. mandarina. Furthermore, sequence analysis of Tpi gene from nine individuals of E. mandarina collected in South Korean localities including Jeju-do clearly showed that all Korean specimens truly belong to E. mandarina.

Japanese/Korean Amynthas carnosus (Goto & Hatai, 1899) is redescribed from a newly designated Neotype (Tokyo NSMT An435). An annotated synonymy is presented that nominally includes: kyamikia Kobayashi, 1934, monstrifera Kobayashi, 1936, sangyeoli, youngtai, kimhaeiensis, sinsiensis and baemsagolensis - all Korean names by Hong & James, 2001, and Taiwanese monsoonus James et al., 2005. However, Chinese A. pingi (Stephenson 1925) (syn. fornicata Gates, 1935) is maintained separately, at least for the present, until its comprehensive review, possibly extending to DNA barcode differentiation.

Ganoderma is a cosmopolitan wood-rot basidiomycete that has been extensively studied for its pathogencity and medicinal properties. Identification of Ganoderma based on macro-microscopic features led to large number of synonyms which resulted in 250 taxonomic names. A Ganoderma species collected from Courtallam, Tamil Nadu was identified as G. cupreum. Phylogenetic analysis inferred from internal transcribed spacer rDNA region resolved the Indian isolate MYC1 as Ganoderma cupreum which clustered with Australian and Asian "cupreum" clade with 85% bootstrap support BS and shared 99% and 98% nucleotide similarity with Malaysian and Australian 'cupreum' respectively. This study represents the first molecular evidence of G. cupreum from Asian origin.

Compare to investigate the taxonomic utility of infragenera system and interspecific of Asian Geranium, we examined the fruit and seed morphology from 35 taxa. The fruit shape and seed's dispersal way did so that may divide subgenus or some part section to do could reason evolutionary trends. That is, at seed dispersal, the awns of section Geranium of subgenus Geranium, ramains attached at the top of rostrum, though fairy easily broken off, because seed increases awn's elasticity by diffusive way, it is long characteristic seed\`s dispersal distance, and subgenus Robertium observed that seed dispersal distance is short because it is no awn's elasticity by way that seed dispersal is gone as awn drops with rostrum. Also, section Geranium of subgenus Geranium and subgenus Robertium act role that awn keeps temporarily breed swerving with mericarp instead of bristle because section Tuberosa of subgenus Geranium is not bristled function that keep temporarily breed because mericarp bristled on base at seed dispersal do while. Therefore, is thought that is talon that when consider formation's development and function regarding this seed dispersal function, subgenus Geraniuum evolves more than subgenus Robertium. Seed morphology can divide by 2 subgenera(Geranium, Robertium) according to pattern of seed coat. and Seed's morphology characteristic(whole shape, color, form of seed apical and base, micropyle area, hilum area, chalaza, and position of seed hilum area), can distinguish some species, but is thought that is not reasonable as for discernment characteristic form and nature by repetition of characteristic form and nature. Especially, infrasection do in fruit and seed's morphology that is handling in this research that know to argue classification system and relationship by repetition of characteristic form and nature difficult. To all reliable truth, cytological, ecological, embryology, and molecular genetics research about talon is considered that should be achieved section Geranium that do not handle yet.

Lactifluus (Pers.) Roussel is an ectomycorrhizal genus that was recently recognized to be distinct from the genus Lactarius. To date, 226 Lactifluus species have been reported worldwide. Misidentification of Lactifluus species is common because of intraspecific morphological variation, cryptic diversity, and the limited number of taxonomic keys available. Molecular data are indispensable for species delimitation; a multilocus phylogenetic analysis showed that most Asian Lactifluus species are not conspecific with morphologically similar species present on other continents. In particular, Korea has misused European and North American Lactifluus names. In this study, we evaluated the taxonomy of Lactifluus in Korea using both morphological and multilocus molecular (ITS, nrLSU, rpb1, and rpb2) data. We examined 199 Lactifluus specimens collected between 1980 and 2016, and a total of 24 species across the four Lactifluus subgenera were identified. All Korean species are distinct and clearly separated from European and North American species. Five taxa corresponded to previously described species from Asia and the remaining 19 taxa are confirmed as new species. Herein, we provide keys to the Korean Lactifluus species within their subgenera, molecular phylogenies, a summary of diversity, and detailed description of the new species.

Molecular biological techniques that recently developed, have made it possible to realize some of new attempts in the research field of rumen microbiology. Those are 1) cloning of genes from rumen microorganisms mainly in E. coli, 2) transformation of rumen bacteria and 3) ecological analysis with nonculturing methods. Most of the cloned genes are for polysaccharidase enzymes such as endoglucanase, xylanase, amylase, chitinase and others, and the cloning rendered gene structural analyses by sequencing and also characterization of the translated products through easier purification. Electrotransformation of Butyrivibrio fibrisolvens and Prevotella ruminicola have been made toward the direction for obtaining more fibrolytic, acid-tolerant, depoisoning or essential amino acids-producing rumen bacterium. These primarily required stable and efficient gene transfer systems. Some vectors, constructed from native plasmids of rumen bacteria, are now available for successful gene introduction and expression in those rumen bacterial species. Probing and PCR-based methodologies have also been developed for detecting specific bacterial species and even strains. These are much due to accumulation of rRNA gene sequences of rumen microbes in databases. Although optimized analytical conditions are essential to reliable and reproducible estimation of the targeted microbes, the methods permit long term storage of frozen samples, providing us ease in analytical work as compared with a traditional method based on culturing. Moreover, the methods seem to be promissing for obtaining taxonomic and evolutionary information on all the rumen microbes, whether they are culturable or not.
