Abstract
A pelagic juvenile (74.0 mm in standard length) of Lepidion inosimae was collected by midwater trawl (0–20 m depth) from the transition waters between the Kuroshio and Oyashio fronts off northeastern Japan. The specimen is characterized by an elongate body, a chin barbel, a minute first ray and non-elongated second ray of first dorsal fin, combination of 55 second dorsal fin rays and 52 anal fin rays, and no ventral luminous organ. This is the first report of early life stages in the genus Lepidion.
