| description | Background and Aims: During an expedition to Atoyac de Álvarez, a poorly explored region of Guerrero, specimens of Salvia with characteristics that are uncommon in Mexican taxa were collected. The aim of this work is to describe and illustrate Salvia ayecarrenoi and discuss its morphological affinities.
Methods: Identification keys were employed to determine the collected specimens to sectional level. A morphological comparison with the taxa of the section Siphonantha was made using literature, herbaria collections and databases. The conservation state of the new species was determined based on the IUCN criteria.
Key results: Salvia ayecarrenoi is a species endemic to Guerrero, with a unique character combination: inflorescences up to 46 cm long, violet-colored flowers, ventricose tube, exserted and curved stamens. The latter characteristic is common in South American species, but rare in Mexican taxa. Thus, its morphology is close to section Siphonantha, a group of five taxa from the Northern Andes. The new species shares some morphological characteristics with Salvia sigchosica. However, it differs from it mainly by the absence of nectar guides, the ventricose corolla tube, the cucullate lower lip of the corolla and the upper stigmatic branch well-developed and longer than the inferior branch. According to the IUCN criteria, the new species is Critically Endangered (CR B1a).
Conclusions: With the description of Salvia ayecarrenoi, the number of Mexican species of Salvia subgenus Calosphace increases to 311. The morphological affinities of the new species place it in a South American section. However, other sections with disjunct distribution have resulted non-monophyletic. Thus, it is necessary to re-evaluate the infrageneric classification of the group and the morphological characters used to circumscribe sections, with the aim of achieving more natural groupings. |

Antecedentes y Objetivos: Durante una excursión a Atoyac de Álvarez, una región poco explorada de Guerrero, se recolectaron especímenes de Salvia con características poco comunes en taxones mexicanos. El objetivo de este trabajo es describir e ilustrar a Salvia ayecarrenoi y discutir sus afinidades morfológicas. Métodos: Se emplearon claves de identificación para determinar los ejemplares colectados a nivel de sección. Se comparó morfológicamente con los taxones de la sección Siphonantha usando bibliografía disponible, colecciones de herbarios y bases de datos. El estado de conservación de la nueva especie se determinó con base en los criterios de la IUCN. Resultados clave: Salvia ayecarrenoi es una especie endémica de Guerrero, con una combinación única de caracteres: inflorescencias hasta de 46 cm de largo, flores de color violeta, tubo ventricoso, estambres exsertos y curvados. Esta última característica es común en especies sudamericanas, pero rara en taxones mexicanos. Por lo tanto, su morfología está cercana a la sección Siphonantha, un grupo de cinco taxones de los Andes septentrionales. La nueva especie comparte algunas características morfológicas con Salvia sigchosica. Sin embargo, difiere de ella principalmente por la ausencia de guías de néctar, el tubo de la corola ventricoso, el labio inferior de la corola cuculado y la rama estigmática superior bien desarrollada y más larga que la rama inferior. De acuerdo con los criterios de la IUCN, la nueva especie está en Peligro Crítico (CR B1a). Conclusiones: Con Salvia ayecarrenoi, el número de especies mexicanas de Salvia subgénero Calosphace aumenta a 311. Las afinidades morfológicas de la nueva especie la ubican en una sección sudamericana. Sin embargo, otras secciones con distribución disyunta han resultado no monofiléticas. Por ello, es necesario reevaluar la clasificación infragenérica del grupo y los caracteres morfológicos usados para circunscribir secciones, con el objetivo de obtener agrupaciones más naturales.
