Chlorella gloriosa (Chlorellaceae, Trebouxiophyceae) was isolated from seawater off the coast of the Dokdo Islands in Korea. An axenic culture was established using the streak-plate method on f/2 agar media supplemented with antibiotics, allowing identification of the isolate by morphological, molecular, and physiological analyses. The morphological characteristics observed by light and electron microscopy revealed typical morphologies of C. gloriosa species. The molecular phylogenetic inference drawn from the small-subunit 18S rRNA sequence verified that the microalgal strain belongs to C. gloriosa. Additionally, gas chromatography-mass spectrometry analysis showed that the isolate was rich in nutritionally important omega-3 and -6 polyunsaturated fatty acids and high-performance liquid chromatography analysis revealed that the high-value antioxidants lutein and violaxanthin were biosynthesized as accessory pigments by this microalga, with arabinose, galactose, and glucose as the major monosaccharides. Therefore, in this study, a Korean marine C. gloriosa species was discovered, characterized, and described, and subsequently added to the national culture collection.

Triceratopyga, is a common and synanthropic genus of medical and forensic significance in eastern Asia which have includes only one species, Triceratopyga calliphoroides. In this study we are reporting the complete mitogenome of the only member of the genus Triceratopyga. The structure of the compete mitogenome is similar with the common ancester fly mitogenome. The size of the mitogenome is 16,529 bp. This is the longest mitogenome recorded from the family Calliphoridae. Although the size of mitogenome is longer than previous records, structure and gene positions are identical with ancestral insect genome.

The aphid genus Stomaphis Walker, 1870 (Hemiptera: Aphididae: Lachninae) is Palaearctic origin group with 30 valid species. It is associated with variable woody host plants, having very long rostrum, which enables them to feed crevices in thick bark of trees. In this study, Stomaphis (stomaphis) pini pini is newly recorded in the Korean Peninsula on Pinus densiflora (Pinaceae). We described morphological features of alate viviparous females, apterous males and oviparous females, respectively. Furthermore, little known forms, sexual morphs of giant oviparous females and dwarfish apterous males are observed.

The genus Etainia Beirne is one of the small group in the family Nepticulidae (Lepidoptera: Nepticuloidea) and is comprising 16 described species in the world. Among them, just four species have been known from the East Palearctic region. As results of taxonomic studies on Korean nepticulids, two species of Etania, E. peterseni Puplesis and E. trifasciata (Matsumura), are newly recognized from Korea. Description and illustrations of diagnostic characteristics including male genitalia for each species are provided with information of host plants.

The genus Pachynoa Lederer, 1863 reported 13 species in the world. This genus was established by Lederer, 1863 have been treated within the genera Pitacanda Moore, 1886 by Hampson, 1896 and Hypermeces Turner, 1933 by Shaffer et al., 1996. Species of the genus Pachynoa are mostly distributed from India and Taiwan to Solomon island. In this study, the genus Pachynoa is newly recorded in Laos with two species, Pachynoa xanthochyta (Turner, 1933) and Pachynoa thoosalis (Walker, 1859). These species are redescribed with illustrations of the adults and the genitalia, and their distribution is updated.

Tineobius Ashmead, 1896 is a relatively small group in the family Eupelmidae. It can be distinguished by the following characters: head with conspicuously lengthened maxillary palpus, mesotibia without apical groove, gaster with deeply emarginate syntergum and filiform ovipositor sheaths. Most species of Tineobius were recorded from Afrotropical, Australasian and Oriental region. However, in Palearctic region, only one species (Tineobius tamaricis Ribes & Fusu) is discovered from Spain by Fusu & Ribes (2017). In this study, the genus Tineobius is reported from South Korea for the first time, with two newly recorded species. Also, a key to South Korean species of Tienobius, diagnoses and photographs of the diagnostic characteristics are provided.

Asaphinae Ashmead, 1904 are the smallest subfamily in Pteromalidae and currently include 27 extant species of 6 genera. Up to date, only 2 species, Asaphes suspensus (Nees) and A. vulgaris Walker, have been recorded from South Korea. Among them A. vulgaris Walker is suspected of misidentified due to several reasons. Hyperimerus Girault, a small genus of the subfamily Asaphinae, consists of two world-wide species. It is close to Asaphes Walker but is separated by the following characteristics: antenna with one anelliform segment; scutellar frenum not distinct; petiole transverse. In this study, we report genus Hyperimerus based on Hyperimerus pusillus (Walker) for the first time from South Korea and Eastern Palearctic region. Also, a key to the genera of Asaphinae from South Korea, diagnosis, photographs of each species and taxonomic note of A. vulgaris Walker are provided.

Harpiphorus, a monotypic genus of subfamily Allantinae (Symphyta: Tenthredinidae), was established based on Tenthredo (Emphytus) lepida Klug. The genus is close to Hemibeleses Takeuchi but can be easily distinguished by the following characteristics: the cell 1M in fore wing with a distinct petiole dorsally and cell M in hind wing closed. Harpiphorus is widely distributed in Europe, but has not yet been found in outside the continent. The larva of this genus is phytophagous attacking the oak species (Quercus trojana Webb and Q. robur L.). As a result of the present study, the genus Harpiphorus is reported based on H. lepidus for the first time from South Korea and the Eastern Palaearctic region. A diagnosis, figures of morphological features are provided.
