A Systematic Revision of the Indo-Pacific Clupeid Fishes of the Genus Sardinella (Family Clupeidae)

抄録

Notes. Many systematists during the past century erroneously regarded this species to be homologous with S. sirm, undoubtedly because the body shapes of the two species are very much similar. However, S. leiogaster is definitely different from S. sirm in having a shorter maxillary like that of S. clupeoides, in having the dorsal inserted midway between the tip of snout and the upper end of caudal base, in having a lower number of gill rakers, and in lacking a series of dark-blue rounded spots along the dorsolateral part of the body.
Distribution. Sardinella leiogaster occurs in the tropical Indo-Pacific waters. It has been reported from the Red Sea in the west, to the Philippines in the east; and from the coasts of the Asian Continent in the north to the shores of the Celebes in the south.
