Streblospio shrubsol..ei..ii

Dear all,
   
    Buchanan (1890) described new spionid worms from England and called them after a person who collected the worms, Mr. Shrubsole, as Hekaterobranchus shrubsolii (later referred to as Streblospio shrubsolii).
    "shrubsolii", with double "i" at the end, has widely been accepted by taxonomists and was also spelled this way by Olga Hartman (1959) in her " Catalogue of the Polychaetous Annelids of the World".
    My question is should we continue using this incorrect spelling or change the name to "shrubsolei", as it is required by the ICZN?
   
    Waiting for opinions!
