摘要
Thrissina splendida sp. nov., described from 19 specimens collected from the coastal areas of Korea and China, is closely related to Thrissina adelae (Rutter 1897), both species having a long maxilla with the posterior tip beyond the pectoral-fin insertion and the snout tip above the eye center level, and similar ventral scute and fin-ray numbers. However, the former is characterized by lower total gill raker numbers on the first, second, third, and fourth gill arches, higher numbers of longitudinal series scale rows, transverse scales, and vertebrae, a shorter snout and lower jaw, a shorter distance between the dorsal and anal-fin origins, and 4th and 5th anal-fin rays, and distinct paired dark lines along the dorsum from the occiput to the caudal-fin base.
