The post-larvae of the lanternfish were collected during 1975-1976 by the R/V“Jinxing”'from the continental shelf of the East China Sea. This report deals with the distribution and morphology of the post-larvae of 7 species of Myctophidae. They are Diogenichthys panurgus Bolin,Myctophum asperum (Richardson) Gonichthys barnesi Whitely, Diaphus theta (Eigenmann et Bigenmann),Diphus lutkeni Brauer, Ceratoscopelus, townsendi (Eigenmann et Eigenmann) and Benthosema pterota (Alcoek). With the exception of Diaphus theta and Benthosem pterota the five others were never recorded before in Chinese waters. A key for identification of the post-larvae is presented.. The occurrence of these fishes in the East China Sea, particularly Diogenichthys panurgus, Myctophum asperum, Gonichthys barnesi and Diaphus lutkeni are governed by the environmental changes, especially by fluctuation of the Kuroshio.
