Abstract The samples obtained during the 2008 Collaborative East‐Antarctic MARine Census ( CEAMARC ) campaign in the S outhern O cean on the TR/V U mitaka Maru contained many specimens of the physonect post‐larval stage known as M ica micula , in varying stages of development, allowing us to complement the existing descriptions. M . micula appears to be endemic to the Southern Ocean, and its possible position in the family P yrostephidae, in particular the species P yrostephos vanhoeffeni , is discussed. For the first time, the definitive nectophores were observed, but they were still too underdeveloped to be assigned conclusively to any known physonect species.
