Colletotrichum acutatum species complex is one of the most important groups in the genus Colletotrichum with a high species diversity and a wide range of host plants. C. acutatum and related species have been collected from different plants and locations in Korea and deposited into the Korean Agricultural Culture Collection (KACC), National Institute of Agricultural Sciences since the 1990s. These fungal isolates were previously identified based mainly on morphological characteristics, and a limitation of molecular data was provided. To confirm the identification of species, 64 C. acutatum species complex isolates in KACC were used in this study for DNA sequence analyses of six loci: nuclear ribosomal internal transcribed spacers (ITS), betatubulin 2 (TUB2), histone-3 (HIS3), glyceraldehyde3-phosphate dehydrogenase (GAPDH), chitin synthase 1 (CHS-1), and actin (ACT). The molecular analysis revealed that they were identified in six different species of C. fioriniae (24 isolates), C. nymphaeae (21 isolates), C. scovillei (12 isolates), C. chrysanthemi (three isolates), C. lupini (two isolates), and C. godetiae (one isolate), and a novel species candidate. We compared the hosts of KACC isolates with "The List of Plant Diseases in Korea", previous reports in Korea and global reports and found that 23 combinations between hosts and pathogens could be newly reported in Korea after pathogenicity tests, and 12 of these have not been recorded in the world.

Ten new species of two families (Suberitidae and Polymastidae) are described from Korea. Six new species in Suberitidae: Plicatellopsis ramosa n. sp., Pseudosuberites anheungensis n. sp. P. youngilensis n. sp., Suberites hwasunensis n. sp., S. chujaensis n. sp. and S. rugosa n. sp. are compared with other similar reported species. All new species differ from previously reported species in morphology, texture, color, skeletal structure, and spicule type. Four new species in Polymastidae: Polymastia fistula n. sp., P. sasuensis n. sp., P. viridis n. sp., and Weberella haengwonensis n. sp. are different from previously reported species in the growth form of papillaes and fistules, color and spicule types. For example, Weberella haengwonensis is similar to Weberella verrucosa in shape, but differs based on surface papillaes and spicule sizes.

Cecidomyiidae (Diptera) consists of six subfamilies, which are divided into three groups according to larval ecological habits (phytophagous, mycophagous, and zoophagous). The five basal subfamilies of Cecidomyiidae consist entirely of mycophagous species, with approximately 1500 species described worldwide and 29 previously known to occur in Korea. In this study, 37 named species (1 Lestremiinae, 29 Micromyinae, 4 Winnertziinae, and 3 Porricondylinae species) are newly reported from South Korea. We excluded Lestremia yasukunii Shinji from the list of Korean mycophagous cecidomyiids as it is a nomen nudum. Therefore, we herein officially recognize 65 species, 30 genera, and four subfamilies for the Korean mycophagous cecidomyiid fauna. We also provide diagnoses and photographs to aid species identification and discussion on the four years of gall midge taxonomic inventory in South Korea.

To analyze nucleotide sequence encoding internal transcribed spacer (ITS) regions specific to the Laminariaceae family, genomic DNA was isolated from six brown algae species distributed along the east coast of Korea. These included three species from the Laminariaceae family (Agarum clathratum Dumortier, Costaria costata [C. Agardh] Saunders, and Saccharina japonica Areschoug) and two species from the Alariaceae family (Undaria pinnatifida [Harvey] Suringer and Ecklonia cava Kjellman), both in the order Laminariales, and one species from the family Sargassaceae in the order Fucales (Sargassum serratifolium). Based on a sequence analysis of ITS-1 and ITS-2 for A. clathratum, C. costata, and E. cava, oligonucleotides were designed from the regions that showed sequence conservation in Laminariaceae. Following polymerase chain reaction using three sets of primers, amplification of ITS-1 and ITS-2 was detected in reactions using genomic DNA isolated from the species belonging to Laminariaceae, but not from the species belonging to the other families. The results indicate that this method can be used for the detection and identification of Laminariaceae species.

Korean species of the subfamily Lycorininae Cushman & Rohwer are reviewed. This subfamily along with three species, Lycorina triangulifera Holmgren, 1859, L. spilonotae Chao, 1980, and L. ruficornis Kasparyan, 2007, are reported for the first time from Korea. In this genus, five species have been reported from the Eastern Palaearctic region, six species from China and two species from Japan. Some species of this subfamily is known as parasitoids of Crambidae and Tortricidae. We report three newly recorded species from Korea, Lycorina triangulifera, L. spilonotae, and L. ruficornis, and provide diagnoses with photographs of lycorinine species and a key to the Korean species.

Seasonal variation of species composition in marine organisms around Oryukdo of Busan was investigated using a gill net between 2009 and 2011. A total of 82 species, 52 families, and 6 taxa were collected during the sampling periods. Species were included two species in Cnidaria, one in Urochordata, 12 in Mollusca, 12 in Crustacea, seven in Echinodermata, and 48 in Pisces. The dominant species were Crepidula onyx, Asterina pectinifera, Ceratostoma burnetti, Asterias amurensis, Anthocidaris crassispina, and Trachurus japonicus. These six species accounted for 48.4% in the total number. Diversity indices were highest in spring 2009 (2.77) and lowest in spring 2011 (1.66). Seasonal variation of species composition and abundance in marine organisms corresponded with the water temperature.

Kim (1970) was an early, comprehensive foundation for the taxonomy of Korean spider wasps. All the species therein are reviewed, and an annotated checklist comprising 21 species is presented. Species names are corrected in terms of current taxonomy. Based on the re-examination of voucher specimens, five misidentifications are rectified, of which two species rectified as Priocnemis(Leptopriocnemis) cyphonota and P.(Umbripennis) pseudojaponica are new to Korea. Also, occurrences of two species (Anoplius eous and An. viaticus) in Korea, which was doubted by Lelej et al. (1994), are confirmed. On the other hand, exclusions of two species (Irenangelus perinx and Priocnemis mitakensis) from the Korean fauna are proposed. However, the need for further study on six species (Anoplius reflexus, An. infuscatus, Arachnospila eisukei or Ar. fumipennis eisukei, Auplopus obtusus, Priocnemis irritablis) historically mentioned for the Korean fauna is newly recognized. The current taxonomic status of those species is briefly discussed.

The family Trigonalyidae Cresson, 1887, is a small group of parasitic wasps (Hymenoptera: Apocrita) comprising around 150 species worldwide. Among them, the genus Taeniogonalos Schulz, 1906 is the richest in species and the most widely distributed. Four species, namely T. fasciata, T. mongolica, T. subtruncata and T. tricolor, were recorded from the Korean Peninsula. The genus is studied here on the basis of a larger collection of material from South Korea. Six species of Taeniogonalos are recognized, including three species that are newly recorded: T. formosana, T. sauteri and T. taihorina. The published record of T. mongolica in Korea currently seems groundless, and this species should be excluded from the Korean fauna. A key to species identification is provided, with illustrations and description of each species. The hitherto unknown male of T. sauteri is described. We also present new biological data on T. sauteri and T. formosana, including the record of a new family of Diptera as secondary hosts for the family.
