Busck (1900) described Aproaerema crotolariella from specimens reared from Crotalaria pumila Ortega, but he misspelled the generic name of the host as “Crotolaria.” Dyar (1901) changed the spelling to A. crotalariella, and this name has been used in other checklists with different generic combinations, Stomopteryx crotalariella (McDunnough, 1938) and Syncopacma crotalariella (Hodges, 1983; Lee et al., 2009). The International Commission on Zoological Nomenclature, ICZN (1999) states that the original spelling of a name is the “correct original spelling” (Art. 32.2) unless it qualifies as an incorrect original spelling due to an inadvertent error, such as a lapsus calami or printer's error (Art. 32.5). The name crotolariella, even though based on the misspelled name of the host genus, is the correct original spelling that Busck used in his text (pg. 226) and explanation of plate 1 (pg. 254). Therefore, it is restored here as the valid name. The subsequent misspelling by Dyar (1903) is an unjustified emendation (Art. 33.2).

I thank Charley Eiseman (Ecological Services, Pelham, MA) for calling attention to this unjustified emendation and Richard Brown (Mississippi Entomological Museum, Mississippi State, MS) and Ronald W. Hodges (Eugene, OR) for their advice in resolving this problem.
