I think wundermanni is a complex which includes boggessi and others from the Western Atlantic. The species was reclassified in 2006 with several new species named based on color patterns that are considered part of the complex. The original wundermanni is considered lost ,I believe. Commonly , in the hobby they are refferred to as wundermanni.
