Description
Although the maximum recorded shell length is 11 mm, it is hypothesised to range from 10mm to 20mm in length.;Original description
"Given that the specific name luctuosa had already been assigned by Hinds to a Californian species within the Pleurotomidae, I found it necessary to introduce cubensis as the new trivial name for this West-Indian shell."
