] showing a distinct to no selenizone at all. Accordingly, the absence of a selenizone is not considered significant for generic classification. Equally, the presence and absence of a protoconch varix and details of teleoconch ornamentation vary extensively between species in the same genus and is also insignificant for beta taxonomy (

The shell appears mature due to the descending apertural margin on the last portion of the whorl. The species is known from a single, but well-preserved specimen. The difference in protoconch sculpture, and the absence of any sign of a selenizone despite the sloping aperture indicating maturity, refutes the possibility of a mislocalized specimen from
