A taxonomic study of the Palearctic species of the genus Brachyserphus is presented. Two species are newly described as B. acuticaudatus sp. n. and B. semipunctatus sp. n. from South Korea and the Russian Far East. B. striatopropodeatus (Kolyada 1997 syn. n.) is synonymized under B. lucens (Provancher 1883) and a key to the Palearctic species is provided.

The subgenus Abstrulia Casey belonging to the genus Tetratoma Fabricius of the family Tetratomidae is distributed ten species over the Holarctic region, including eight Palaearctic species. In East Asia, four species from Russian Far East and two species from Japan have been recorded, respectively. In the Korean Peninsula, two species, T. (A.) ainu (Nakane) and T. (A.) pictipennis Reitter, were reported up to date, and latter species is newly recorded in South Korea in this paper. A redescription, habitus photograph, and illustrations of diagnostic characters of the species are provided, with a key to species of the subgenus Abstrulia.

A new species, Monoblastus forsythia sp. nov. is described from South Korea. All specimens of this new species were collected on Forsythia koreana (Nakai). A taxonomic study of South Korean Monoblastus was initiated by Uchida in 1930, and until now four species have been recorded from South Korea. The genus Monoblastus is a Holarctic genus with 31 described species, 14 species are Nearctic, seven are Western Palaearctic region, and nine species occur in Eastern Palaearctic region. In the study, I provide description and photos of both sexes of this new species. Also, modified key to species of the South Korean Monoblastus is provided.

In this study, traditional culture method and 16S rRNA gene analysis were applied to reveal the composition and diversity of lactic acid bacteria (LAB) of fermented cow milk, huruud and urum from Baotou and Bayannur of midwestern Inner Mongolia. Also, the quantitative results of dominant LAB species in three different types of dairy products from Baotou and Bayannur were gained by quantitative polymerase chain reaction (q-PCR) technology. Two hundred and two LAB strains isolated from sixty-six samples were identified and classified into four genera, namely Enterococcus, Lactococcus, Lactobacillus, Leuconostoc, and twenty-one species and subspecies. From these isolates, Lactococcus lactis subsp. lactis (32.18%), Lactobacillus plantarum (12.38%) and Leuconosto mesenteroides (11.39%) were considered as the dominated LAB species under the condition of cultivating in MRS and M17 medium. And the q-PCR results revealed that the number of dominant species varied from samples to samples and from region to region. This study clearly shows the composition and diversity of LAB existing in fermented cow milk, huruud and urum, which could be considered as valuable resources for LAB isolation and further probiotic selection.

The subfamily Pimplinae is one of the largest groups of the family Ichneumonidae, currently 1,737 species in 77 genera worldwide. In Korea, 120 species in 33 genera have been recorded. The South Korean species of the subfamily Pimplinae Wesmael, 1845 (Hymenoptera: Ichneumonidae) are the focus of this study. Here, six species are newly added in the South Korean fauna: Aravenator kamijoi Momoi, Chablisea varicolor Liu, He & Chen, Clistopyga arctica Kusigemati, Liotryphon cydiae (Perkins), L. strobilellae (Linnaeus), and Zaglyptus semirufus marginatus Kasparyan. Of these new taxa, two genera (Aravenato and, Chablisea) belonging to the tribe Ephialtini are also newly recorded from South Korea. We present a key to species of South Korean Clistopyga, Liotryphon, and Zaglyptus, diagnosis, photographs, and distribution. As a result of this study, the Korean fauna of Pimplinae is now known to consist of 126 species in 35 genera. All Pimplinae specimens are kept in the collections of the Geolim Entomological Institute (GEI), Daegu, South Korea.

The first zoeas of Nursia rhomboidalis and Pyrhila carinata were obtained from laboratory condition. They are described and illustrated for the first time. Morphological comparison with those of other Korean described species of the family Leucosiidae reveals that the zoea of N. rhomboidalis is very similar to those of Myra fugax and Arcania undecimspinosa based on characteristics of the carapace spines length, the antenna morphology, the maxilla endopod setation, and the telson, whereas, the zoea of Py. carinata coincides well with those of Philyra kanekoi and Pyrhila pisum based on characteristics of the carapace spines length, the antenna morphology, the maxilla endopod setation, and the telson. Furthermore, we find that at least two groups of zoeas exist in the Korean species of the subfamily Ebaliinae. A provisional key to the known zoeas of ten leucosiid species from Korean waters is provided.

We analyzed the hair microstructure of Korean small terrestrial mammals, such as Rodentia and Lagomorpha, to classify the characteristics of hair morphology. Micromys minutus showed a unicellular irregular type of medulla structures; on the other hand, the other mammals showed multicellular structures. Regarding the cuticular scale structures, the Rodentia species exhibited a narrow and broad diamond petal type, while the Lagomorpha species exhibited an elongated petal type. Interestingly, the hair cross-sections showed quite unique characteristics. We constructed hair identification keys to distinguish species with a single hair. The dichotomous key of Rodentia and Lagomorpha can be used for their behavioral ecology and dietary analysis of upper predators to serve as the basis for ecological research.

Aggregate and solitary zooids of salps were collected from April 2001 to June 2009. By the analyses based on the morphological characteristics, four species in the genus Cyclosalpa of the subfamily Cyclosalpinae are identified as new records in Korean waters: Cyclosalpa affinis (Chamisso, 1819), Cyclosalpa bakeri Ritter, 1905, Cyclosalpa sewelli Metcalf, 1927, and Cyclosalpa polae Sigl, 1912. These species are re-described with illustrations and photographs in this study. In addition, a key to species of the genus Cyclosalpa in Korean waters and a key to the life cycles of Salpida are provided. As a result of this study twelve species in the Salpidae have been reported from Korea until now.

Acervus (Pyronemataceae, Pezizales) is a saprobic genus in Pezizomycetes, characterized by colored apothecia, subcylindrical to cylindrical asci and guttulate ascospores. We collected four Acervus samples from China and Thailand. Descriptions and illustrations are introduced for all fresh samples. One new record of A. globulosus from Thailand, one new species, A. rufus, two known species, A. epispartius and A. stipitatus from China are reported. Phylogenetic analysis based on five genes, the large subunit rRNA (LSU), the translation elongation factor-1 alpha (tef1-α), the second largest subunit of RNA polymerase II (rpb2), the largest subunit of RNA polymerase II (rpb1), and the small subunit rRNA (SSU), revealed the distinct position of the new species. The new species is set apart by its red apothecia. A key to Acervus species is also given.
