Abstract A new deep sea balanomorph,
Tetrachaelasma
tasmanicum sp. nov., is described. This new record is based on numerous
disarticulated plates, from dredge samples around deep-sea seamounts on the
South Tasman Rise. This is the deepest known occurrence of the Balanomorpha,
and the first record of
Tetrachaelasma from the Pacific realm. An
overview of the biogeography, including aspects of the palaeontology of deep
sea balanomorphs is provided. A map showing station localities and a list of
deep sea cirripedes recovered from the South and East Tasman Rise during the
1995
Rig Seismic cruise, are included.
