Maynard (1920a: 80) first used the binomen Strophiops santesoni in error as one of three taxa that, in rare cases, may have a shell encircled by a band of color.  As this character is not diagnostic of S. santesoni, this passage cannot be considered a description of the taxon and the usage is a nomen nudum.   This usage also include a clearly incorrect reference to a subsequently published figure (Maynard, 1920b:fig. 59) that was captioned "S. nuda Mayn."   Earlier on the same page is another reference to fig. 59 that correctly refers to it as S. nuda.  Maynard (1920d:112) published a correction to the first usage on page 80, stating "for santesoni read persuasa."  This statement makes it clear that the intended figure reference was fig. 59* (Maynard, 1920b), which is captioned "S. persuasa M. & C. x2, banded below suture."  The next usage of the name S. santesoni appeared in a discussion of sinistrality in Cerions (Maynard, 1920a:81).  Again, the text notes that this rare character is present in both S. santesoni and S. inconstans, and the usage is a nomen nudum.  However, it does include a reference to a subsequently published illustration (Maynard, 1920c:fig. 62) that was captioned "S. santesoni."

 As the publication of the association of a new species group name (Maynard, 1920a:81) with an illustration (Maynard, 1920b:fig. 62) of the taxon being named prior to 1931 was interrupted, the name Strophiops santesoni became available only when the requirements of the relevant Articles (Articles 10.1.1 and 12.2.7, ICZN, 1999:9, 17) have been met.  The name Strophiops santesoni Maynard, 1920 became available July 10, 1920 upon publication of figure 62, prior to the intended description of this species (Maynard and Clapp in Maynard, 1921b:139, Plate 36, figs. 3, 4;  pl. 15, fig. 5).  Due to Maynard's unintended taxonomic act, both the date of publication and the authorship of Strophiops santesoni were altered.
