Diagnose: The new species is similar to Hechtia iltisii but it differs by its silvery lepidote blade at base (vs glabrous), smaller spine distance (3.4–13.4 vs 5–30 mm), inflorescence sterile branches absent (vs present), triangular rose petals (vs ovate green) and green anthers (vs yellow).

Etymology: The specific epithet refers to the Herbarium Luz María Villarreal de Puga (IBUG), of the Instituto de Botánica of the Universidad de Guadalajara, where the project Flora of Jalisco is being carried out and the alma mater of the first and fourth authors.
