Four specimens of the odontobutid fish, Odontobutis obscura (Temminck et Schlegel) of the family Odontobutidae were collected for the first time from Koje Island, Kyongsangnam-do, Korea. Odontobutis obscura was easily discriminated from congeners in that this species have no sensory canals at preoperculomandibular and supraorbital pit lines on head and the first band on lateral side of body is extending from the middle of the first dorsal fin. This species distributes in western Japan mainly and Koje island which situates southernmostly in Korean Peninsula. So a new Korean name "Nambangdongsari" is proposed.

The taxonomic research based on extensive investigations and specimen collections throughout all varieties of freshwater and marine habitats of Chinese waters, including mainland China, Hong Kong and Taiwan, which involved accounting the vast number of collected specimens, data and literature (both within and outside China) were carried out over the last 40 years. There are totally 361 recorded species of gobioid fishes belonging to 113 genera, 5 subfamilies, and 9 families. This gobioid fauna of China comprises 16.2% of 2211 known living gobioid species of the world. This report represents a summary of previous researches on the suborder Gobioidei. A recently diagnosed subfamily, Polyspondylogobiinae, were assigned from the type genus and type species: Polyspondylogobius sinensis Kimura & Wu, 1994 which collected around the Pearl River Delta with high extremity of vertebral count up to 52-54. The undated comprehensive checklist of gobioid fishes in China will be provided in this paper.

1983년 7월부터 1995년 10월까지 국내에서 채집된 망둑어아목 어류 4과 28속 51종을 대상으로 몸의 부위에 따른 비늘의 종류와 미병부 측면 비늘의 형태를 조사 비교하였다. Luciogobius grandis, L. guttatus 및 Leucopsarion petersi를 제외한 48종은 비늘을 가지고 있었으며, 비늘은 즐린과 원린의 2종류로 구분되었다. 특징적인 것은 동일 개체 내에서도 어체의 각 부위에 따라 종류, 형태, 크기, 초점의 위치, 구와 융기선수 및 소극수 등이 다르게 나타나지만 속과 종 수준에서 비교적 안정된 특징을 보여주었으며, 비늘의 유무와 그 종류에 따라 망둑어아목 어류는 5개의 group으로 분류되었다. 미병부 비늘의 형태는 5각형, 6각형, 원형 및 타원형으로 구분되었다. 또한 Odontobutis obscura interrupta, O. platycephala 및 Hypseleotris swinhoni는 2∼3열의 소극을 가지고 있고, Eutaeniichtys gilli와 Parioglossus dotui는 비늘의 초점이 중앙에 위치하고 있어 다른 망둑어아목 어류와 차이를 나타내었다.

Gobiids are hyperdiverse compared with other teleost groups, with about 2,000 species occurring in marine, freshwater, and blackish habitats, and they show a remarkable variety of morphologies and ecology. Testing the effectiveness of DNA barcodes on species that have emerged as a result of radiation remains a major challenge in evolutionary biology. Here, we used the cytochrome c oxidase subunit 1 (COI) sequences from 144 species of gobies and related species to evaluate the performance of distance-based DNA barcoding and to conduct a phylogenetic analysis. The average intra-genus genetic distance was considerably higher than that obtained in previous studies. Additionally, the interspecific divergence at higher taxonomic levels was not significantly different from that at the intragenus level, suggesting that congeneric gobies possess substantial interspecific sequence divergence in their COI gene. However, levels of intragenus divergence varied greatly among genera, and we do not provide sufficient evidence for using COI for cryptic species delimitation. Significantly more nucleotide changes were observed at the third codon position than that at the first and the second codons, revealing that extensive variation in COI reflects synonymous changes and little protein level variation. Despite clear signatures in several genera, the COI sequences did resolve genealogical relationships in the phylogenetic analysis well. Our results support the validity of COI barcoding for gobiid species identification, but the utilization of more gene regions will assist to offer a more robust gobiid species phylogeny.
