We statistically evaluated a population found on the Nebrodi Mountain (NE Sicily) to verify if the observed morphological differences with the already known taxa justified the description of a new one. It resulted in being sufficiently distinct to deserve recognition at the species level.<h4>New information</h4><i>Centaureavaldemonensis</i>, a new species endemic to Sicily is described and illustrated here. It is confined to the Nebrodi Mountains (NE Sicily). The distinction of this taxon from the others belonging to the <i>C.busambarensis</i> complex has been supported with the aid of statistical analyses on morphological characters.
