Mammillaria ser. Stylothelae is a well-recognized group in southern Chihuahuan Desert. Some members of this series have been regarded as highly polymorphic species. Recent analyses showed that some populations of those species complex can be accepted as independent species. In this study, we analyzed and compared quantitative and qualitative characters to identify a putative new species. We compared it with close geographical and morphological species of the series. Based on our findings, we described a new endemic species of M. ser. Stylothelae from Querétaro, Mexico. The new taxon is distinctive by the globose growth form, small size, the number of central and radial spines, presence of fibrous roots, naked axils and non-arillate seeds. Additionally, we provided information about habitat and the preliminary status of conservation of the new taxon.
