A marine algal species was collected from Sacheonjin, Gangneung located on the eastern coast of Korea during a survey of marine algal flora. This alga shares the generic features of Membranoptera belonging to the subfamily Delesserioideae and is characterized by the presence of combined features of membranous, monostromatic thalli attached by a solid discoid holdfast, blades with a conspicuous terete stipe-like midrib and microscopic lateral veins, entire margins, irregularly alternate to dichotomous branching, and obtuse apices growing apically. In a phylogenetic tree based on rbcL sequences, the Korean alga nests in the same clade with M. alata from the eastern North Atlantic. The genetic distance between both the sequences within the clade was calculated as 0.0%. Based on the morphological and molecular analyses, this Korean species is identified as the generic type, M. alata. This is the first record in the list of Korean marine algal flora.

A newly recorded species, Aora pseudotypica Hirayama, 1984, belonging to the family Aoridae Stebbing, 1899 was collected from Geomundo and Jejudo Islands in South Korea. This species is characterized by having large triangular process on basis of male gnathopod 1. It is morphologically similar to A. typica Krøyer, 1845, but distinguishable by the lack of a large rounded process on the anterior margins of basis and ischium on male gnathopod 1 and having small distal segment on outer ramus of uropod 3. To date, only two genera, Aoroides Walker, 1898 and Grandidierella Coutière, 1904, of the family Aoridae have been recorded in Korea, so this is the first record of the genus Aora from Korea.

The present study summarizes the occurrence, distribution and autecology of 12 taxa of the class Cyanophyceae collected from several swamps, reservoir and highland wetlands in South Korea from 2009 to 2012. A new species, Anabaena koreana sp. nov. and 11 taxa of blue-green algae newly recorded are described and illustrated. Anabaena koreana is similar to A. oumiana, A. spiroides and A. crassa in that the trichomes form regular coils. However, A. koreana is distinguished from these three species by the morphological characteristics of the vegetative cell, heterocyst, and akinet shape and size. This study considers 12 blue-green algal species, including a new species, Anabaena koreana sp. nov. and 11 species that are recorded for the first time in the Korean freshwater algal flora. Among them, the genus Nostochopsis Wood ex Bornet et Flahault 1886 had not previously been recorded in Korea.

The study introduces the genus Mycobilimbia, from South Korea. M. philippina is reported here as being new to the country. Characteristic features of the species are crustose thallus, globose apothecia, K-proper exciple and hypothecium, Biatora-type asci, 3-septate fusiform ascospores, and a lack of secondary compounds.

Thirteen species of sea lice (Copepoda, Caligidae) are described as parasites of marine fishes from Korea including three new species such as Pseudocaligus longipes n. sp. from Siganus fuscesens (Houttuyn), Lepeophtheirus tamladus n. sp. from Sebastes inermis Cuvier, and Lepeophtheirus gusevi n. sp. from Sebasetes schlegeli Hilgendorf. Remaining ten species are new to Korea: Caligus elongatus Nordmann, 1832; C. equulae Ho and Lin, 2003; C. fistulariae Yamaguti, 1936; C. laticaudus Shiino, 1960; C. rotundigenitalis Y$\ddot{u}$, 1933; Metacaligus uruguayensis (Thomsen, 1949); Lepeophtheirus atypicus Lin, Ho and Chen, 1996; L. parvulus Shiino, 1952; Anuretes quadrilaterus Shiino, 1954; and Pseudanuretes chaetodontis Yamaguti, 1936.

We reported an unrecorded plant species, Galium bungei var. miltorrhizum (Hance) Jeong & Pak in Korea. This species is found in Gyeonggi-do, Chungcheongbuk-do, Jeollabuk-do, Gyeongsangbuk-do, and Gyeongsangnam-do. G. bungei var. miltorrhizum is distinguished from related taxa by glabrous stem and glabrous or rarely short papillate mericarps. This taxon was named 'Dung-geun-ne-ip-gal-kwi' in Korean based on shapes of leaves. We provided a description, illustrations, photographs, and a key of related taxa in Korea. And we propose a new combination (Galium bungei var. miltorrhizum).

This study intended to record a species of feather mite, Neopteronyssus bilineatus Mironov, 2003, (Arachnida: Pteronyssidae), from a grey-capped pygmy woodpecker, Yungipicus canicapillus (Blyth, 1845), in the Republic of Korea. Mite samples were collected from the flight feathers of a woodpecker, preserved directly in 95% ethyl alcohol, and then observed by a light microscope after specimen preparation. Morphology of Neopteronyssus bilineatus is distinguished from other pici group species by opisthosoma part with 2 longitudinal bends, tarsal seta rIII 3 times longer than tarsus III in males, and 2 elongated hysteronotal plates extending beyond the level of setae e2 in females. In the present study, a species of feather mite, N. bilineatus, was newly recorded from Y. canicapillus in Korean fauna.

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.

Mite of the genus Hypoaspis of family Laelapidae are free-living soil predators mostly observed on the open grass field. Five species in the genus Hypoaspis were listed in Korean Catalog (NIBR, 2013) without detail information. Recent series of soil acarine biodiversity survey in Gyeongbuk and Gangwon provinces during 2009-2015 recovered a new record of Hypoaspis sardous (Canestrini, 1884) to Korean inventory from apple orchard and riparian grass land. Detailed description and morphological comparison with the related species, H. aculeifer which is well known biological control agent of horticultural crop pests were provided with identification keys.

The Cymatium Roding, 1798 is a small- to large-sized marine gastropod genus. Three species has been reported thus far for Cymatium in the Korean waters. In general, Cymatium encausticum (Reeve, 1844) is known to occur in tropical seawaters including the Philippine Islands along with its congeners C. gutturnium, C. springsteeni, and C. exile. A single individual of the species was collected from Jejudo Island by SCUBA diving and morphological features were observed using a stereomicroscope. This is the first study to report the occurrence of Cymatium encausticum (Reeve, 1844) from the Korean waters, providing a detailed description of the species with the illustration for the shell morphology.
