The osteological characters of Aphyocypris chinensis of subfamily Leuciscinae were examined and the systematic position of this species is discussed through comparison with other species of subfamilies Leucisicinae and Cultrinae. Numbers of the dorsal an danal fin ray, having no symphyseal knob and barbels and separation between dermosphenotic and supraorbital, are in acord with those of subfamily Leuciscine, and the abdominal keel and trigemino-facial nerve foramen of the prootic are more closely related with those of subfamily Cultrinae. But several diagnostic characters detected only in this species are as follows ; 4 infraorbitals, the shape of ethmoid, 5-6 hypurals, the broad orbital width, having no extrascapular, incomplete lateral line and considerable small size.

Two leptocephali [total length (TL) 68.2-80.5 mm] from the family Ophichthidae, collected from the waters south of Jeju Island, Korea, were identified using morphology. The two ophichthid leptocephali were identified as belonging to the genus Ophichthus based on morphological characters: 131-132 myomeres; nine gut swellings; dorsal fin origin above the middle of the body; five postanal pigments present from the anus to the caudal margin. Ultimately, both leptocephali were identified as Ophichthus asakusae, as the total number of myomeres was consistent with those of adult O. asakusae. Here, we first describe the morphological characteristics of the O. asakusae leptocephalus, and suggest diagnostic characters for leptocephali belonging to the genus Ophichthus.

Berberis chitria (family Berberidaceae) has a close affinity with B. aristata, used in traditional systems of medicine as a drug 'Daruharidra' for skin disease, jaundice, affection of eyes, and rheumatism. Keeping this in view, in the present study attempts have been made to identify marker characters of B. chitria in order to differentiate the two species. Some of the diagnostic features of the root are patches of pericyclic fibre, pitted sclerieds and berberine containing cells and heterocyclic medullary rays. Besides, the physicochemical characters such as total ash; acid insoluble ash; alcohol and water soluble extractive; tannins; sugar and starch percentages has shown variations. The percentage of berberine as berberine hydrochloride was also calculated through HPTLC densitometric method and it was found little higher than B. aristata and B. asiatica i.e. 3.16%. Thus, this species can be utilized as a possible substitute to Daruharidra.

To reexamine the taxonomic characters of Deutzia coreana, D. tozawae, and D. triradiata, which were belonged to Subsection Coreanae of genus deutzia in Korea, the stellate trichome in the leaf, one of the major diagnostic characters, was investigated with the stereo and scanning electron microscopes. The number of trichome was nearly equal in both sides of the leaf, while the ray was mainly 4 and 5 in D. coreana. However, there was little trichomes in the upper surface of D. tozawae, and in the lower surface of D. triradiata. D. tozawae had 3, 4-rayed trichomes in leaf surfaces, and D. triradiata 3-rayed ones, respectively. As a result, these three species were also distinguishable by the stellate trichomes in the leaf.

Berberis tinctoria (Berberidaceae), commonly known as Nilgiri Barberry is a common allied species to B. aristata, used in India Traditional Systems of Medicine by the name of 'Daruharidra' for skin disease, jaundice, affection of eyes, and rheumatism. Keeping this in view, in the present study attempts have been made to identify marker characters of B. tinctoria. Some of the diagnostic features of the root are patches of pericyclic fibre, pitted sclerieds, crystals, berberine containing cells and heterocyclic medullary rays. Besides, the physicochemical characters such as total ash; acid insoluble ash; alcohol and water soluble extractive; tannins; sugar and starch percentages has also shown some variations. The percentage of berberine as berberine hydrochloride was also calculated through HPTLC densitometric method and it was found almost similar to B. aristata, B. asiatica and B. chitria i.e. 3.36%. Thus it can be explored as a possible source of substitute to B.aristata.

Two species of the chloroperlid stonefly, Alloperla medlata and Sweltsa illiesi, are reported for the first time in Korea. Alloperla mediata can be distinguished by the smaller epiproct and the presence of a median sclerite under epiproct in male, and by the modified subgenital plate in female. Sweltsa illiesi can be distinguished by the presence of a pair of ridges on tergum 9 in male and upward V-shaped pattern on the center of head in adults. The line drawings of diagnostic characters and taxonomic remarks of the two species are provided with keys and comparative characters for adults of Korean Chloroperlidae.

We identified the five root-lesion nematode species, Pratylenchus crenatus, P. fallax, P. kumamotoensis, P. panamaensis and P. penetrans from intercepted in quarantine inspection over the past five years. Their diagnostic characters are including number of lip annuli, stylet length, shape of the labial region, presence or absence of males, structure of lateral fields, shape of spermatheca, length of the post-vulval uterine sac and shape of tail and so forth. We described the photos, measurements and morphological characters.

Two marine harpacticoid copepods are newly recorded from Korea : Eudactylopus specitabilis (Brian, 1923) and E. andrewi Sewell , 1940. Six species are currently recognized in the genus Eudactylopus, multitidue of which were often disputed among authors on their taxonomic status, so we treat here the taxonomic features of the two species above on the basis of specimens from South Sea and East Sea of Korea. E.spectabilis occurred first outside the Mediterranean Sea. and is fully redescribed with illustrations. Important male characters like the shape of leg 2 endopod and leg 5 with its setal arrangement are particularly emphasized as the diagnostic characters.

During a systematic study on Korean nudibranchs, two phyllidiid and two polycerid species were collected and identified with examination of their external morphological characters. As a result of the study, two phyllidiid species, Phyllidia ocellata Cuvier, 1804 and Phyllidiella pustulosa (Cuvier, 1804) were redescribed since there was no descriptions of these species with Korean specimens. And two polycerid species, Thecacera pennigera (Montagu, 1815) and Triopha catalinae (Cooper, 1863) were described as new to Korean fauna. Diagnostic characters of these species are described with illustrations in this study. DNA barcode data from three species examined were also provided for a supplement to morphological identifications.

The subgenus Idioglochina Alexander, 1921 belongs to the genus Dicranomyia Stephen, 1829 and has a special habitat unlike other congeners. The larval stage inhabits marine algae near the intertidal zones. The most distinctive characters are found in the antennae with inner face of flagellar segments extended to produce a serrate form. A total of 30 species of the subgenus Idioglochina are recorded with the distribution is restricted to the Pacific and Indian Ocean regions. In this study, the subgenus and its species D. (I.) tokara (Nobuchi, 1955) are newly added to the Korean fauna. This species was previously recorded in Japan as an endemic species, but it was collected from Jeju Island. A redescription, period of activity, habitat information, and photographs of diagnostic characters of the species are provided. The female ovipositor is photographed for the first time.
