| description | Background and Aims: During explorations in the outer limits of the Natural Protected Area Sierra de Tacuichamona, an endemic-rich area of Sinaloa, Mexico, a new species of Coutaportla (Rubiaceae) was discovered. This paper describes and illustrates Coutaportla helgae, provides an identification key, a distribution map, and discusses the morphological and geographic relationships with the rest of the species of the genus.
Methods: Botanical collections were made during 2021 and 2022, and 15 herbariums and digital databases were reviewed to compare with other species of the genus and to locate possible additional localities. A distribution map was prepared using the polygon of the Sierra Madre Occidental as a base.
Key results: Coutaportla helgae stands out from the rest of the species of the genus by having the smallest flowers of the group. It is morphologically related to C. lorenceana as they are the only species of the genus with subapical placentation and calyx lobes less than half the length of the fruit, but it differs in having smaller flowers, a shrubby habit and distribution in tropical deciduous forest.
Conclusions: With the present discovery, Coutaportla reaches four endemic species to Mexico and five overall, considering C. guatemalensis. Coutaportla helgae contributes new characteristics to the genus by having smaller flowers and growing at lower altitudes than the rest. Additionally, elements are provided to support the conservation of sites with high biodiversity and endemism such as the Sierra Tacuichamona. |

Antecedentes y Objetivos: Durante exploraciones en los límites exteriores del Área Natural Protegida Sierra de Tacuichamona, zona rica en endemismos de Sinaloa, México, se descubrió una especie nueva de Coutaportla (Rubiaceae). El objetivo del presente trabajo es describir e ilustrar a Coutaportla helgae, proveer una clave de identificación y un mapa de distribución, y discutir las relaciones morfológicas y geográficas con el resto de las especies del género. Métodos: Se realizaron colectas botánicas durante 2021 y 2022, y se revisaron 15 herbarios y bases digitales para comparar con otras especies del género y localizar posibles localidades adicionales. Empleando el polígono de la Sierra Madre Occidental se elaboró un mapa de distribución. Resultados clave: Coutaportla helgae se destaca del resto de especies del género al poseer las flores más pequeñas del grupo. Se relaciona morfológicamente con C. lorenceana al ser las únicas especies del género con placentación subapical y lóbulos del cáliz menor a la mitad del largo del fruto, pero se diferencia de esta por tener flores de menor tamaño, corolas blanco-púrpuras, hábito arbustivo y distribución en selva baja caducifolia. Conclusiones: Con el presente descubrimiento, el género Coutaportla llega a cuatro especies endémicas de México y cinco en total, considerando a C. guatemalensis. Coutaportla helgae aporta nuevas características al género, pues posee las flores más pequeñas y crece a menores altitudes que el resto. Adicionalmente, se aportan elementos para apoyar la conservación de sitios altos en biodiversidad y endemismos como la Sierra Tacuichamona.
