Two new species of Werneria (Compositae, Senecioneae) are described from the highlands of central Peru on the basis of morphological evidence, namely W. huascarana and W. rockhauseniana. In addition, the misinterpreted taxonomic entity W. weberbaueriana is properly circumscribed according to the protologue. A neotype is designated for the name W. weberbaueriana. A key to the Werneria species occurring in the Peruvian department of Ancash is also presented. When data are certain, conservation status is assessed.
