Abstract

Background and Aims: Salvia is the most diverse genus within the Lamiaceae family, with approximately 1000 species with a cosmopolitan distribution, Mexico is one of the main centers of diversity, particularly for the subgenus Calosphace. Oaxaca is the state with the highest richness and endemism in the country, and new species continue to be described. During botanical explorations in Santa Catarina Ixtepeji, specimens were collected that did not match the morphological characteristics of any known species of Salvia. The objective of this work is to propose and describe Salvia itziana as a new species to science.
Methods: Specialized literature on the subgenus Calosphace was reviewed, and taxonomic keys were used to determine the section of the specimens. The iNaturalistMX platform was consulted to search for additional photographic records. A morphological description, an illustration of the species, a distribution map, a conservation status assessment, and an identification key for the species of section Scorodoniae present in the state of Oaxaca were prepared.
Key results: Salvia itziana is described as a new species of section Scorodoniae, subgenus Calosphace. Its conservation status is suggested as Critically Endangered (CR). The new species exhibits foliar and floral characteristics different from the other analyzed species. The most conspicuous features at first glance are the broadly ovate leaves and petioles longer than the blade. This species is endemic to Oaxaca and occurs in Quercus forests of the type locality.
Conclusions: Salvia itziana is known only from its type locality, which could be at risk due to its proximity to a human settlement. With this discovery, the number of Salvia species in Mexico increases to 313, and to 113 for the state of Oaxaca.
