Abstract
Notosudid larvae of two genera and five species, Ahliesaurus brevis, Scopelosaurus smithii, S.mauli, S.harryi and S.“sp.II”of Bertelsen et al. (1976), were recorded from the ocean of southern Japan.Japanese names are given to them, together with tropical Indo-Pacific species S.hoedti and except for S.“sp.II”whose species name is not erected due to the absence of metamorphosed specimens.The descriptions confirm those given by Bertelsen et al. (1976), providing some additional information, especially concerning the youngest stages.A marked change in larval pigmentation during notochord inflection is shown.A key to the notosudid larvae recorded from the waters of Japan is provided.
