Baker, A. N. 1998. The rediscovery of Echinus elevatus Hutton 1872 in New Zealand, and a new name for Acanthotrema Baker & Rowe 1990 (Echinodermata: Echinoidea). Journal of the Royal Society of New Zealand 28, 281-286.
The rediscovery of the holotype of Echinus elevatus Hutton 1872, and living material of this species in northern New Zealand, indicates it to be a species of Amblypneustes Agassiz, of which the Australian species A. pachistus H.L. Clark 1912. is a synonym. There is no evidence for the presence of Holopneustes inflatus Lutken 1872 in New Zealand waters. The generic name Kermabrissoides is proposed for Acanthotrema Baker and Rowe 1990 (preoccupied).
