Type species by original designation: Oliva arctata Marrat, 1871.
A mono-typic genus-group taxon distributed in the Western Indo-Pacific realm (Andaman province) and Central Indo-Pacific realm (Sunda Shelf province).The type species is very similar to Miniaceoliva Petuch & Sargent, 1986, but has a very wide filament channel. As this seems to be the only discriminating character distinguishing it from other Central Indo-Pacific species, the validity of the genus-group taxon is doubtful.
The type species is Oliva arctata Marrat, 1871 (see below).
