Synonymy:
  • clarefacta Dyar, 1919 (Ozamia) - MONA 1983: [NEW]; TL: Orizaba, Mexico.
  • Taxonomic Notes: Ozamia clarefacta (Dyar, 1919), formerly treated as a subspecies of Ozamia fuscomaculella (Wright, 1916), is raised to full species status, apparently based on color and range, in Neunzig (1997). However, the two apparently cannot be separated by DNA barcode supporting the treatment. Heinrich (1956) treated clarefacta as a "variety (or race)" of fuscomaculella.
