The hepialid species, Korscheltellus lupulina (Linnaeus) is newly recorded from Korea. A female specimen of K. lupulina was collected on Jeju Island, southern Korea. This species can be distinguished by the whitish linear marking on the postmedian and dorsum of the forewing but these markings are often unseen in females. The female genitalia can be diagnosed by the semi-rounded ninth abdominal tergum, a pair of semi-rounded ninth abdominal sternum with weakly produced, semi-rounded central plate-shaped medial region, a pair of narrow band-shaped subanal plates, the short, thin ductus bursae, and the large, ball-shaped corpus bursae without a signum. Currently, there are four genera and five species of the Hepialidae distributed in Korea.

During a survey of marine algal flora, two gigartinalean species were collected from Pohang and Youngdeok located on the eastern coast of Korea. They share the generic morphological features of Dumontia. One is characterized by cylindrical to complanate thallus with multi- and uniaxial structure, somewhat inflated and contorted branches, and hollow medulla and cortex consisting of progressively smaller cells outwards. The other shows basically the same features as the former species but was smaller in size, as having 4-7 cm in thallus length and 1-2 mm in branch width rather than 15 and 2-5 mm. Both species are distinguished from each other only by these morphometric features. However, it is supported by molecular analysis that both species are genetically distinct. In a phylogenetic tree based on internal transcribed spacer sequence, the two species nest in the same clade as Dumontia contorta and D. alaskana, respectively. The genetic distance between both sequences within the clade was calculated as 0.0 0.2%, considered to be intra-specific for Dumontia. Based on the morphological and molecular analyses, the two Korean species are identified as D. contorta and D. alaskana described originally from Netherlands and Alaska, respectively. This is the first record of the two Dumontia species in Korea.

Three economic marine algae that have been used as food and carrageenan sources were collected from Korea during a survey of marine algal flora. They share the generic features of Hypnea, and three major clades supported by the sectional features were confirmed in a phylogenetic tree based on rbcL sequences. The first species, which belongs to a species group corresponding to the sect. Spinuligerae, nests in the same clade with Hypnea yamadae in a genetic distance of 0%. It is morphologically characterized by an entangled base, subcompressed or subterete to terete axes, somewhat percurrent main axis, irregularly alternately branching with wide angle, and rarely hooked spinous branchlets. The second one is also referred to the sect. Spinuligerae and formed the same clade as Hypnea cenomyce. The genetic distance between both sequences was calculated as 0.0-0.1%, which is considered to be intraspecific. This species is distinct by somewhat entangled thallus at the basal part, percurrent axis, short spine-like branchlets densely covering the axis, and medullary lenticular thickenings. The third alga, which forms a species group corresponding to the sect. Pulvinatae, nests in the same clade as Hypnea nidulans (no intraspecific divergence). It shows occasionally epiphytic habitat rather than epilithic habitat of low mat-forming growth and percurrent erect main axes with dense lateral branchlets. Based on these morphological and molecular data, the three Korean species are identified as H. yamadae, H. cenomyce, and H. nidulans. This is the first record of the Hypnea species in Korea.

This study reports a new record of freshwater fish Macrognathus aral (Bloch & Schneider) from Aiechu-Kalikhola tributary of the Maukhola river in Sarpang, Bhutan. The species was found in shoal of the tributary and was identified using its morphometric characters. It can be identified and distinguished from its congeners reported in Bhutan by dorsal fin rays XIX, 47, anal fin rays III, 52, rostral plates 28, pectoral fin rays 19, caudal fin rays 15, soft rayed part of dorsal and anal fin separated by a notch from rounded caudal fin, and presence of four ocelli at the base of dorsal fins. Further studies are needed to better understand its distribution, ecology, and population dynamics in the country. A key to species belonging to Mastacembelidae of Bhutan including the new record is provided.

One Iravadiid shell Iravadia (Fluviocingula) elegantula (A. Adams, 1861), from the brackish waters in Kangwon-do was recorded as new to the Korean molluscan fauna. The shell is typically solid and narrowely ovate-conic. The protoconch is small, planorboid to depressed dome-shaped, typically with a minute first whorl. Including the new records in this study, the family Iravadiidae contained 2 genera and 3 species in the Korean water.

A new record of the eyeshade sculpin Nautichthys pribilovius is described on the basis of a single specimen collected from the East Sea, Korea. The species has 23 second dorsal fin rays, rounded spines on the occiput, a black band through the eye and across the cheek, branched caudal fin rays and a branchiostegal membrane attached to the isthmus. The new Korean name "Gum-eun-tti-nun-hoet-dae-sok" is proposed for the genus Nautichthys, and "Gum-eun-tti-nun-hoet-dae" is proposed for the species N. pribilovius.

Three species of the family Biphyllidae - Biphyllus japonicus Sasaji, 1983, Biphyllus loochooanus Sasaji, 1991 and Biphyllus oshimanus Nakane, 1988 - are reported for the first time in Korea. Descriptions, photographs of the adults and line drawings of the diagnostic characters are provided for all the species recognized in this study.

Sciaphila secundiflora occurs on Jeju Island as a second species of the genus Sciaphila in Korea. This is an important finding in relation to the flora of Korea, as species of the genus Sciaphila are concentrated mainly in Indonesia and Malaysia. Few species are found on the mainland of Asia, in Japan, Taiwan, China (Hainan), tropical Africa, Australia, and on the Pacific islands. In this paper, the species S. secundiflora is described and illustrated as a new record from Korea. In addition, we suggest that the species of the genus Sciaphila should be protected with regard to its habitat characteristics and for its phytogeographic and climatic significance.
