The equivalence of "US-ian" and the even rarer spelling "Uessian" is maintained by the American Dialect Society:

• 1947, American speech, page 245:

  a year later Benjamin F. Stovall, of Atlanta, Ga., proposed Uessian or US-ian (pronounced you-ess-ian)

The date given, 1937, is at odds with other sources suggesting the 19th century, and contradicted by an earlier mention of "Uessian" in the League of Nations Chronicle, March 30, 1930 (quoted in Allen Walker Read, America: naming the country and its people, 2008:59) as well as by the American Library Association:

• 1948, Richard Sealock, Pauline Seely, Bibliography of place name literature: United States, Canada, Alaska, and Newfoundland, page 39:

  Literary digest 124:2 Nov. 13, 1937 Suggests 'Uessian' (US-ian) instead of 'American' ...

The derived term is attested in the title of the book:

U.S.iana (1650-1950) : a selective bibliography in which are described 11,620 uncommon and significant books relating to the continental portion of the United States
