제주도 남부 해역에서 채집된 Ptereleotris evides (망둑어목: 청황문절과) 한국 첫기록 = First Record of Ptereleotris evides (Gobiiformes: Microdesmidae) from the Southern Jejudo Island, Korea

다국어 초록 (Multilingual Abstract)

A single specimen (30.35 mm standard length) of Ptereleotris evides was collected from the southern coast of Jejudo Island, Korea, in September 2017 during a skin diving outing. Ptereleotris evides is characterized by having a slightly elongated body, six spines on the 1st dorsal fin, one spine and 25 soft rays on the 2nd dorsal fin, 22 pectoral fin rays, one spine and four soft rays on the pelvic fin, one spine and 25 soft rays on the anal fin, and no disc in pelvic fin. This species differs from the congeneric species, P. hanae and P. heteroptera in having no elongated rays on the caudal fin and a black spot at the ventral margin of the caudal peduncle, respectively. Molecular analysis results based on mitochondrial DNA cytochrome c oxidase subunit I (COI) sequences showed that our specimen almost corresponded to P. evides (99.82%) sequences from registered at the NCBI. As this is the first record of P. evides in Korean waters, we propose a new Korean name for it, “Ga-mak-cheong-hwang-mun-jeol”.
