  • One specimen of Albula argentea (296.3 mm in standard length), belonging to the family Albulidae, was collected in a set net in the coastal waters of Jejudo Island, Korea. As the adult A. argentea has not been caught from Korean waters, we described its morphological characters based on the collected specimen and compared them with those of the previous reports on A. argentea and A. koreaus. As a result, the present specimen was characterized by having 68~73 pored lateral line scales (vs. 77~78 for A. koreana), 72~73 vertebrae pored lateral line scales (vs. 77~80) and none streak on the check (vs. yellowish streak). Molecular analysis using the mitochondrial cytochrome b DNA sequences was also conducted to confirm the correctness of species identification and taxonomic status of the sample.

  • To clarify the taxonomic status of five specimens of Albula collected from Korea and Taiwan (Albula sp.), genetic differences among them and other congeneric species were investigated based on mitochondrial DNA cytochrome b sequences. All five specimens of Albula sp. showed identical haplotypes and strongly supported a monophyletic group on phylogenetic analysis. The genetic differences between Albula sp. and ten other species of Albula ranged from 0.100 to 0.164. These values were almost equal to or exceeded the interspecific differences among the latter ten species (0.038-0.206). Morphological comparisons of Albula sp. and another four Indo-Pacific species, A. argentea, A. glossodonta, A. oligolepis and A. virgata, are also presented. Albula sp. could be distinguished from the latter four species in their numbers of pored lateral-line scales, anal fin rays and vertebrae, as well as in several proportional measurements.

  • A single leptocephalus specimen of Albula glossodonta belonging to the family Albulidae under the order Albuliformes, was collected from the southern sea of Korea in May 21, 2019. This species is distinguished from A. vulpes in the number of melanophores at the base of the caudal fin. In addition, our specimen was readily distinguished from A. argentea in having no melanophores on the operculum, at the base of the dorsal fin and in front of the pectoral fin. Also it was well distinguished from A. gilberti in having no melanophores on the operculum, in front of the pectoral fin and on the lateral body. A molecular analysis based on 467 bp sequences of the mitochondrial DNA 16S rRNA shows that the leptocephalus is well matched to A. glossodonta adult (K2P distance=0.002). We report the first occurrence of A. glossodonta leptocephalus in the Korean waters, and propose it's new Korean name, "Nam-bang-yeoeul-myeol".
