  • A single juvenile pomacentrid specimen (5.9 mm standard length) was collected from the Korea Strait in October 2010. The specimen is characterized by punctate-stellate melanophores scattered on the operculum and dorso-ventral region in front of the caudal peduncle, the lack of melanophores on the posterior end of the anal fin base, the presence of 14 spines and 14 soft rays on the dorsal fin, and the presence of 2 spines and 12 soft rays on the anal fin. A molecular analysis based on mitochondrial DNA 16S rRNA sequences showed that this specimen is closely related to adult Chromis mirationis (d = 0.002), but that it differs from Chromis notata (d = 0.017). Juvenile C. mirationis differ from juvenile C. notata in having no melanophores on the posterior end of the anal fin base. We propose a new Korean name, "tti-ja-ri-dom" for C. mirationis.

  • Argyreia gyrobracteata Traiperm & Chitchak (Convolvulaceae) is newly recorded in Vietnam. It is similar to A. mekongensis Gagnep & Courch in having a white campanulate corolla but differs from that species by having whitish surface of the abaxial leaf, narrowly lanceolate or linear-oblong, curly, rolled up the bract with a longer length of the petiole and a shorter pedicel. It was previously known only in Thailand, but was recently found in Lam Dong Province, Vietnam, for the first time. The present study provides a detailed description, colorful photos and the distribution of the species. Furthermore, a comparison of the diagnostic characters between this species and a related species in Vietnam, A. mekongensis Gagnep & Courch, is provided.

  • A single specimen of Synodus fuscus belonging to the genus Synodus in family Synodontidae was firstly collected from the coastal waters of Jeju Island, Korea. We newly add this species to the Korean fish fauna and propose its new Korean name, "Mo-rae-kkot-dong-myeol". This species was characterized by having no conspicuous pigmented area on operculum. The dorsal fin base is shorter than 1/2 of the head length. The morphological measurements and counts of Synodus fuscus were described in detail and a key to species of the genus Synodus from Korea provided in this study.

  • A single specimen of Caranx melampygus (113 mm standard length), belonging to the family Carangidae, was firstly collected by a set net from the coastal waters of Jejudo Island, Korea. This species is morphologically similar to C. sexfasciatus except for the posterior end of maxilla not reaching the posterior margin of eye (vs. reaching in C. sexfasciatus) and no black blotch on the upper part of opercle (vs. black blotch). We newly add this species to the Korean fish fauna and propose its new Korean name "Jag-eun-ip-jul-jeon-gaeng-i" for the species because it has relatively smaller upper jaw when compared with C. sexfasciatus.

  • Sargassum filicinum Harvey, a brown alga (Phaeophyceae) native to Northeastern Asia, has been recently reported from the coast of Southern California (USA). Here we report the occurrence and range extension of this introduced species, as we found the alga at La Jolla and Rancho Packard in Todos Santos Bay, Baja California, Mexico. The first collections of S. filicinum correspond to several immature plants, found on September 8, 2005, drifting in the intertidal zone at La Jolla. Later on November 9, 2006, we found a well-established population in Rancho Packard in the middle intertidal zone to 2 m depth. Since S. filicinum is an annual monoecious species with air bladders, the risk there is a high risk of spreading rapidly along the Pacific, as in the case for S. muticum. The population in Rancho Packard extends 500 m along the coast, consisting mainly of young plants with an average length of 30 cm and a density of 5 thallus/m2. This is the first record of this invasive species for the Mexican Pacific coast, and it represents the southern limit along the Pacific coast of North America. This finding suggests that this invasive species has successfully colonized the Pacific coast of North America and its distributional range is still expanding.

  • Three leptocephali (22.2, 22.7, 56.0 mm in total length) collected from the East/Japan Sea were identified by morphological and genetic analyses as belonging to the genus Scolecenchelys (Anguilliformes, Ophichthidae). Morphologically, the specimens were characterized by 148-158 myomeres, 10 gut swellings, dorsal fin origin above middle of the body, and 6 postanal melanophores between the anus and the caudal margin. An analysis of an 849-base pair 12S rRNA sequence of mitochondrial DNA showed that sequences are concordant with those of adult Scolecenchelys fuscogularis (genetic distance = 0.001). Furthermore total number of myomeres is consistent with the total number of vertebrae in adult S. fuscogularis. This study provides the first description of the morphological characteristics of S. fuscogularis leptocephali and their variations with size. The Korean name of S. fuscogularis is "Ga-neun-mul-baem", established by Ji et al. (2012).

  • This article analyzes the record structure, content designation, and the content of UNIMARC, USMARC, and KORMARC formats for authorities, through the comparative investigation, Structure and content designation are almost same with those of the bibliographic formats, being based on those of ISO 2709. The data fields of USMARC and KORMARC are divided into blocks based on the traditional authority card formats, and those of UNIMARC are divided into functional blocks based on the GARE. Record contents of the formers in the fixed-length fields include more elements on the selectioa status and scope of the heading, and those related to the series. And those of the later include more elements for the international exchange. Based on the analysis of the variable fields, it is recommended that KORMARC should include an additional subfield, say $(\blacktriangledown\;j)$ for the processing of the Hanja(Chinese character) data and add the separate classification fields for series.

  • This is the first report of Chaetodontoplus melanosoma, belonging to the family Pomacanthidae, collected in Korea. The specimen (123.1 mm in standard length) was caught in the coastal waters of Jejudo Island by a trammel net on 23 February 2010. This species was characterized by the following morphological traits: 26 dorsal fin rays, 16 pectoral fin rays, 6 pelvic fin, 21 anal fin rays, no blue strips on the body, no markings behind the eye, and an egg-shaped faint black spot on the base of the pectoral fin. We suggest a new Korean name "Geom-eun-cheong-jul-dom" for C. melanosoma.

  • A single specimen (174.5 mm in standard length) of Cantherhines multilineatus, belonging to the family Monacanthidae in the order Tetraodontiformes, was first collected from northern Jeju Island, Korea, in August 2016, using a gill net. This species is distinguished from the congeneric species C. dumerilii by the lack of spines on the sides of its caudal peduncle (vs. two pairs of spines in C. dumerilii) and from C. pardalis in having 9-10 narrow dark longitudinal bands on the cheek and side (vs. dark brown with a network of close-set polygonal spots in C. pardalis). The species also very similar to Stephanolepis cirrhifer, but its first dorsal fin spine is more elongated than the rays of its second dorsal fin rays. We have adopted the Korean common name "Jul-mu-nui-jwi-chi" for C. multilineatus, in accordance with the proposal of Yamada et al. (2009).

  • During June 2017, we collected two postflexion larvae (6.01 and 7.56 mm in standard length [SL]) and two juveniles (7.72 and 9.62 mm SL) belonging to Myctophidae in the waters of Jejudo Island. Those four individuals were identified as Diaphus garmani, which had not been reported in Korea. They were distinguished from Benthosema pterotum by melanophores in the abdominal cavity (absent in D. garmani vs. present in B. pterotum) and the development of photophores (developed in D. garmani vs. rudimentary in B. pterotum) when shorter than 10.0 mm SL. Analysis of 16S rRNA sequences showed that the sequences of four individuals matched those of adult D. garmani (Kimura 2-parameter distance: 0.6-0.8%). This is the first record of larvae and juveniles of D. garmani in Korean waters, and we propose a new Korean name, Gar-ma-ni-sat-bi-neul-chi.
