The gempylid fish genus Epinnula is reviewed and two species are recognized. The type species E. magistralis is considered restricted to the western Atlantic Ocean and a new species from the Pacific Ocean is described. The new species, Epinnula pacifica sp. nov., can be distinguished from E. magistralis by 17 or 18 dorsal-fin rays (vs. 15 or 16 in E. magistralis), 15 or 16 anal-fin rays (vs. 13 or 14), 247-268 total scales on lower lateral line (vs. 285-330), a deeper body, relatively high dorsal fin as reflected by the relatively long fin spines and rays, longer dorsal-fin and anal-fin bases, longer pectoral fin, and longer pelvic fin and pelvic spine.
对蛇鲭科鱼类Epinnula属进行了综述，并确认了两个物种。模式种E. magistralis被认为仅限于西大西洋，并描述了一个来自太平洋的新物种。新物种Epinnula pacifica sp. nov. 与E. magistralis的区别在于，背鳍鳍条有17或18根（而E. magistralis为15或16根），臀鳍鳍条有15或16根（而E. magistralis为13或14根），体侧下部有247 - 268片总鳞片（而E. magistralis为285 - 330片），身体更深，背鳍相对较高，表现为鳍棘和鳍条相对较长，背鳍和臀鳍基部较长，胸鳍较长，以及腹鳍和腹鳍棘较长。
