ICZN article 188.8.131.52. In the case of a diacritic or other mark, the mark concerned is deleted, except that in a name published before 1985 and based upon a German word, the umlaut sign is deleted from a vowel and the letter "e" is to be inserted after that vowel (if there is any doubt that the name is based upon a German word, it is to be so treated).
The genus Stensiöina was named in honor of Erik Stensiö, a Swedish paleozoologist.
Loeblich and Tappan (1957) spelled the genus Stensioeina and so does a majority of recent authors.
Several species were published using the spelling Stensiöina and Stensioina.
