Stigmella ulmivora (Fologne, 1860) Beirne, 1945

Hofmann (1858) named a species Nepticula ulmella HS. from Regensburg. This name should be regarded as an unavailable name (nomen nudum), since there is no description nor indication. This name is also a nomen oblitum, never cited again until Segerer (1997) synonymised it with S. ulmivora. Thus no further action needs to be taken to reverse precedence to avoid rejecting the junior synonym S. ulmivora or junior homonym Nepticula ulmella Braun, 1917 (now Ectoedemia ulmella).
