한국산 매퉁이속(매퉁이과, 홍메치목) 어류의 분류학적 재검토

Abstract

Taxonomic review of the genus Saurida was conducted based on three species (Saurida macrolepis, Saurida microlepis and Saurida wanieso) collected from Korea between 2006 and 2017, and two species (S. elongata, S. macrolepis) loaned from Japan. Saurida undosquamis and S. elongata were not found in this study. Saurida wanieso can be readily distinguished from Saurida tumbil by following characteristics: outer palatine teeth (2 rows in S. wanieso vs. 3-4 rows in S. tumbil) and pectoral fin length (reaching to pelvic - dorsal line in S. wanieso vs. not reaching to pelvic - dorsal line in S. tumbil). In counts, the four Saurida spp. are well distinguished: number of lateral line scales (48-50 in S. macrolepis vs. 54-57 in S. wanieso vs. 61-62 in S. elongata vs. 63-70 in S. microlepis), vertebrate (47-49 in S. macrolepis vs. 51-53 in S. wanieso vs. 57-59 in S. elongata vs. 62-64 in S. microlepis). Molecular analysis using 437 bp mitochondrial DNA cytochrome oxidase subunit I (COI) sequences showed three species were well distinguished. Saurida macrolepis was the most closely clustered with S. wanieso (d=0.159-0.184), and S. wanieso was the farthest clustered with S. microlepis (d=0.189-0.216).
