The samples obtained during the 2008 Collaborative East-Antarctic MARine Census (CEAMARC) campaign in the Southern Ocean on the TR/V Umitaka Maru contained many specimens of the physonect post-larval stage known as Mica 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 Pyrostephidae, in particular the species Pyrostephos 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.
