The species of the genus Entoloma recorded in Korea until now are arranged with Korean Entoloma monography. It was made with modified keys of classification of Hesler and Noordeloos. On the basis of it, the genus Entoloma of Korea is classified into 7 subgenera, 10 sections, and 80 species.

Two problematic subgenera of Tomoceridae (Collembola, Insecta) were investigated for their phylogenetic relationships based on morphological characters and allozyme study from three relevant species. Different dendrograms were obtained obtained between morphological and allozyme studies. The morphological data did not give rise to any result distinctive enough to separate the two subgenera whereas the allozyme analysis produced a clear separation by the high genetic distance value. They were consistent, however, whether given rise to by using distance or cladistic methods and also whether character weighting or unweighting approaches employed in the morphological character analysis. As a consequence, it is strongly suggested that any prominent morphological trait might work as a good taxonomical character when supported by a strong genetic divergence as evidenced by allozyme analysis for instance.

Larvae and pupae of Simulium (Eusimulium) satsumense were collected and recorded from Korea for the first time. Detailed descriptions and photographs of both immatures are provided. Currently, 42 species are known from the subgenus Eusimulium, which is found globally, mainly in the Holarctic Region, but unknown from Korea. Members of the subgenus Eusimulium are morphologically homogeneous in male, female, and pupa, making them extremely difficult to distinguish from one another. S. (E.) satsumense can be distinguished from other Korean black flies by the following combination of the characteristics: Pupa: Gill of four slender filaments, dorsalmost filament strongly divergent from other filaments; cocoon slipper shaped without anterodorsal projection; Larva: Head spots distinctly positive; postgenal cleft short, apically rounded or squared; antenna with proximal segment brown; abdominal segments IX with prominent ventral tubercles; and rectal papillae of three simple lobes. In addition to descriptions for larvae and pupae of the species, a key to genera and subgenera of Simulium of Korean black flies are also provided.

The relationship of nine Medicago species belonging to four subgenera were analyzed by using SDS-PAGE and restriction fragment length polymorphism (RELP) methodologies. Sixty-eight bands of alcohol and salt soluble proteins and 85-133 RFLP markers were used to estimate the genetic distance among the species. These species were clustered together at around 0.1 to 0.4 level of distance for both kind of markers, indicating that Medicago species have a large genetic similarity. A combined cluster diagram, at a dissimilarity level of 0.3, differentiated nine species in four groups: group 1, M. littoralis , M. truncatulam, M.scutellata and M. rigidula; group 2, M. sativa ; group 3, M. lupulina ; group 4, M. orbicularis, M. radiata and M. minima. All of them, but except for M. minima. corrensponded to the existing four subgenera of the genus Medicago classified by Lesins and Lesins(1979).The most similar species were M. littoralis and M. trucatula and the most dissimilar one was M. lupulina. In separate cluster diagrams based on RFLP and protein markers, some differences were observed. In the case of RFLP or DNA markers, M. sativa (alfalfa) was distantly clustered with other Medicago species. But in the case of protein markers, M. sativa was closely clustered with M. scutellata, M. littorulis and M. truncatula.

Allium taxa of Korea were taxonomically reviewed, and classified as three subgenera, ten sections, seventeen species, and three varieties. Among these, Korean endemics were recorded as six taxa; A. koreanum, A. taquetii, A. deltoide-fistulosum, A. linearifolium, A. thunbergii var. deltoides, A. thunbergii var. teretafolium. In addition, A. condensatum, A. splendens and A. maximowiczii proved to distribute only in North Korea. Keys to the subgenera, sections, species and infraspecies with descriptions of each taxon were provided.

Short-palped crane flies belonging to the genus Epiphragma Osten Sacken, 1860 (Diptera: Limoniidae: Limnophilinae) have a worldwide distribution except the Afrotropics, with the highest diversity in Neotropics and Oriental Region. They are divided into four subgenera: Eupolyphragma Alexander, 1948, Epiphragma s. str., Lipophragma Alexander, 1978, and Parepiphragma Alexander, 1960. Diagnostic characters and wing photographs of all subgenera are given. Genus Epiphragma was previously unknown from the Korean Peninsula. Species Epiphragma (Epiphragma) gracilistylus Alexander, 1933 is newly recorded for North Korea, E. (E.) subfascipenne Alexander, 1920 is newly recorded for South and North Korea, and E. (E.) subinsigne Alexander, 1920 is newly recorded for South Korea. These species are taxonomically revised, and the taxonomic status of E. (E.) gracilistylus is discussed. We present an identification key and redescriptions and illustrations of both sexes from all species in Korea. Redescription of larva and pupa of E.(E.) subfascipenne is presented. Elevation range, period of activity, habitat information, general distribution, and a distribution map in Korean Peninsula is given for each species.

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.

The history of investigation of the family Velutinidae from 1776 to the present day is briefly described in the last part of this review; the contemporary system of the family, consisting of 39 species and subspecies, belonging to 17 genera and subgenera, and three subfamilies, is presented here. A biogeographic analysis of the fauna has been made, the history of origin and development of the family, vertical distribution and relation to substrates have been described in this work.

Phylogenetic relationships among the Korean taxa of the genus Allium subgenus Rhizirideum and some related taxa were assessed on the basis of in sequences of nuclear ribosomal DNA. Twenty-eight accessions of the genus Allium L. consisting of subgenera Rhizirideum (19 taxa), Allium (5 taxa) and Amerallium (one taxon) were analyzed. The variation in the ITS region was informative at the levels of section except for sect. Reticulato- bulbosa which is known to be of multiple origin. The ITS 2 region was longer than the ITS 1 region, and all of the investigated Allium taxa were the same in length in the 5.8S region except for A. monanthum. Allium cyaneum var. cyaneum was the shortest (635 bp) and A. victorialis the longest (646 bp) among the investigated Korean taxa. The three morphologically similar taxa, A. thunbergii, A. sacculiferum that has been included in A. thunbergii, and A. deltoid- fistulosum, had the same ITS lengths of 641 bp, but were clearly distinguished in the phylogenetic analysis of their ITS sequences.
