>Andrew G. asserted that the proper genus was Tuba I. Lea, 1833, which is an earlier name for the genus Gegania Jeffreys, 1884.  However, Wenz (1939; p. 663) deemed Tuba I. Lea, 1833 to be invalid because that same genus name, Tuba, was employed for a different set of animals by Fabricius in 1822.<
>The species you're discussing can be called Gegania valkyrie Powell, 1971, and it may also be called Tuba valkyrie (Powell, 1971) if Andrew is correct and Wenz isn't.  <

There's an ICZN ruling in favor of Tuba Lea.  This would make Tuba valkyrie (Powell, 1971) the correct name.  Vaught is an author who used Gegania, which is how her name came into the discussion.
