One of the largest genera of subfamily Ophioninae, Ophion, has been reported 144 species in the World. Nevertheless, recorded members of genus Ophion are 40 species in the Eastern Palaearctic region, 8 in South Korea (O. ainoicus, O. choaspese, O. flavopictus, O. fuscomaculatus, O. luteus luteus, O. obscuratus obscuratus, O. okunii, O. takaozanus). In this paper, a taxonomic list of genus Ophion from South Korea is provided for the first time. Two newly recorded species, Ophion hokkaidonis Uchida and Ophion nikkonis Uchida, are reported from South Korea. A key to these South Korean species, diagnoses of the two newly recorded species and digital images are provided.

The aim of this study was to discover and describe new genera and species of cyanobacteria in Korea. Aquatic and aerial algae were collected from various environments in the Han River and Nakdong River watersheds between August 2009 and October 2015. As a result, one genus and six species of cyanobacteria were newly recorded in Korea. The newly recorded genus for Korea was Capsosira; newly recorded species were Capsosira brebissonii, Rivularia minutula, Chamaesiphon amethystinus, Leptolyngbya margaretheana, Pseudanabaena arcuata, and Rhabdoderma lineare.

The subfamily Ennominae is one of the most species-rich taxa of Geometridae that include more than 9,700 species worldwide and over 280 species in South Korea. Herein, we present the first report of five species of Ennominae. Abraxas flavisinuata can be characterized by the white wings, a thick black postmedial line that is medially and dorsally broken with an orange band, large rounded black discal dots on the forewing, and a black dotted postmedial line on the hindwing. Lomographa claripennis can be characterized by the whitish wings, the black undulating postmedial line as well as the minute blackish discal dot on the forewing, and the black undulating postmedial line with a minute black discal dot on the hindwing. Arichanna tetrica can be characterized by the grayish forewings, thick black transverse ante- and postmedial lines, a large blackish discal dot, whitish apical streak on the forewing, and scattered black dots on the whitish hindwing. Apocleora rimosa can be characterized by the brown ground color of the fore- and hindwings, the black slanted ante- and postmedial lines of the forewing, and two black medial lines on the hindwing. Ourapteryx japonica can be characterized by the white wings, the dark brown transverse ante- and postmedial lines with a long discal dot on the forewing, and the dark brownish transverse antemedial line as well as a termen that has a sharp white tail with one large dark reddish dot and one small black dot on the hindwing.

Three halacarid species belonging to the genus Copidognathus are recorded from the shallow subtidal sands at Ko Taenae Islet (sand dune) off Ko Pha-Ngan Island, Thailand: Copidognathus thailandicus n. sp., C. euryalus Bartsch, 1997 and C. orarius Otto, 2001. Copidognathus thailandicus n. sp. comes close with C. cribrosoma (Police, 1909) and C. cribellus Bartsch, 1993 due to dorsal plates completely covered with rosette pores. Dissimilarities among them are discussed. Copidognathus euryalus and C. orarius are recorded hove for the first time from Thailand and away from its type locality. The present paper is also the first contribution on the taxonomy of Halacaridae (Acari) from Thailand.

Two marine ulvalean species (Chlorophyta) were collected from the southern and eastern coasts of Korea. One is morphologically characterized by usually unbranched or little branched ribbon-shaped thalli, fronds with spirally twisted basal portions and usually undulate margins and 1 (-2) pyrenoids per cell. The other has irregularly shaped thalli, undulate and dentate margins in the fronds, small macroscopic denticulations along the margin and (1-) 2-3 pyrenoids per cell. In phylogenetic tree based on molecular data, the two species nest in the same clade with Ulva flexuosa and U. rigida, respectively. These two Korean entities are identified as U. flexuosa and U. rigida, respectively, based on morphological and molecular analyses. This is the first record of Ulva flexuosa and U. rigida in Korea.

In Korea, 104 species of Notodontidae have been recorded. The genus Odontosia H$\ddot{u}$bner is characterized by the elongate and serrate margin of its forewing and the prominent harpe of valva and many spinular cornuti on the vesica of the male genitalia and the robust ductus bursae and large, ovate and sclerotized corpus bursae of the female genitalia. Only one species of Odontosia, O. patricia Stichel, 1918, has been reported from Korea. In this paper, Odontosia sieversii ($M\acute{e}n\acute{e}tri\grave{e}s$, 1856) is newly added to the Korean fauna based on three male specimens collected at Mt. Bangtaesan, Gangwon-do, Korea. Diagnosis for the species and photographs of adult and genitalia of the genus Odontosia are provided.

The continuous exploration in deep seawater from Korea makes us lead the discovery of ancient Chlorophyta, Palmophyllum, in the Korean coast. The phylogenetic analyses of 18S rRNA and rbcL genes demonstrate that our specimens are Palmophyllum crassum (Naccari) Rabenhorst, recorded in Japan and clearly distinguished from P. umbracola from New Zealand and California, USA. Palmophyllum crassum grows in the subtidal region, 8-30 m deep, and has a crustose thallus which is closely adherent to substrates such as non-geniculate crustose coralline algae, sponge, shells, or rocks. P. crassum is composed of numerous spherical cells embedded in the gelatinous matrix. The discovery of this ancient green seaweed implies that the Korean coast is one of the hotspots of algal species diversity and has the suitable marine environment for algal speciation. We suggest the grounds to conserve the Korean coast environmentally as the biodiversity center of marine species by studying the phylogeny of seaweeds.

Protein spectra from 6 species of Gossypium were obtained by disc electraphoresis of seed extracts. Protein extracts were made by soaking 0.5g. of seed in 15ml of Tris-glycine buffer for 24 hours. Gels 24 hours. Gels were stained in 0.5% Amido Black solution for 1 hour, and destained in 7% acetic acid for 72 hours. Nine to 15 bands were visible in each gel. Homologies of Protein bands among the species were determined by migration velocity. Evidences obtained from electrophoretic separation of seed Protein were consistent with those from genetic, cytological, morphological and Phenogenetic methods regarding the origin of New World cultivated cottons. Possibility, however, does not exist to exclude Gossypium herbaceum from one of the Progenitors of New World cultivated cottons from electrophoretic evidences alone.

Myelochroa (Asahina) Elix & Hale is a common foliose lichen genus found on the Korean Peninsula. Since it was first recorded nearly two decades ago, no detailed taxonomic or revisionary study of the genus has been conducted. Thus, the current study was conducted to carry out a detailed taxonomic and revisionary study of Myelochroa in South Korea. This study was based on specimens deposited in the Korean Lichen Research Institute (KoLRI). Detailed taxonomic studies and a literature review confirmed the presence of twelve species of Myelochroa from S. Korea, including one new record, Myelochroa xantholepis (Mont. & Bosch) Elix & Hale. Descriptions of each species with their morphological, anatomical and chemical characters together with a key to all known Myelochroa species are presented.

Three ciliate species, Frontonia schaefferi Bullington, 1939, Spathidium curiosum Foissner, 2016, and S. muscicola Kahl, 1930, were collected from freshwater and terrestrial habitats in Korea. Their morphology was investigated based on live observations and protargol impregnation. Frontonia schaefferi was characterized by a cell size of $89-112{\times}45-53{\mu}m$ (after protargol impregnation) and three vestibular kineties. Spathidium curiosum was characterized by a cell size of ca. $125{\times}25{\mu}m$ in vivo and the unusual shape of the extrusomes. Spathidium muscicola was characterized by a cell size of ca. $135{\times}40{\mu}m$ in vivo and four to six macronuclear nodules. These three species are new records for Korea.
