摘要

The dimorphic soft coral genus Minabea Utinomi, 1957, originally described from Japan, is here recognized as a monotypic taxon and restricted to the type species, which is designated as Minabea phalloides (Benham, 1928). Minabea ozakii Utinomi, 1957, previously recognized as the type species, cannot be morphologically differentiated from M. phalloides, and is therefore considered a synonym. In light of the present situation in which Benham's and Utinomi's type specimens cannot be located, and Benham's type locality is uncertain, recently collected material from New Zealand is here described in detail. Eight other taxa, including one new species, which superficially resemble Minabea, are allocated to a new genus, which is morphologically distinct and has an Indo-West Pacific distribution. The new species has recently been discovered from Okinawa and the Philippines. The Indian Ocean Specimens upon which the species Alcyonium indicum Thomson and Mackinnon, 1905, and Bellonella indica Thomson and Henderson, 1905, were based have been reexamined, and it has been determined that they are conspecific and belong to the new genus. These are compared with the new species. In addition, newly-collected material of a recently described Melanesian species has allowed for an assessment of phenotypic variability, which is most marked of any species in the genus. Revised keys and a table comparing the nine species in the two related genera, along with a discussion of variability and distribution, are also included.
