| description | Background and Aims: During biological explorations in the thorn forest near the coast of Sinaloa, specimens of four taxa not previously reported for this state were collected, including the first record of the genus Castela, being also a species new to science. The objective of this work was to describe and illustrate Castela juyyaania, as well as to report three additional new records for the flora of Sinaloa that share habitat with the new species.
Methods: Botanical collections in northern Sinaloa during 2022 and 2023 were carried out. For the description of the new species the available literature of the genus Castela was reviewed, and specimens from local herbaria and electronic databases were consulted. An identification key to the species of the section Castela in Mexico, distribution map, a table comparing the most similar species and vulnerability assessment (according to the International Union for Conservation of Nature (IUCN)) were prepared. Photos and updated distribution maps are presented for the new records.
Key results: Castela juyyaania is microendemic to the Peninsula El Guachapori in the north of Sinaloa. It grows in thorn forest near the coast, in an area of approximately 25 km2, highly threatened by agricultural expansion. According to the IUCN criteria, it is considered Critically Endangered. It is morphologically similar to the C. erecta complex, but differs in having petiolate leaves, not conspicuously revolute margins, styles present and non-reticulate seeds. The distribution area presents some elements of the Sonoran Desert, including the new records Ebenopsis confinis, Gossypium davidsonii and Malpighia diversifolia.
Conclusions: With the new addition, the genus Castela reaches seven species in Mexico with four endemics, consolidating it as its main center of diversity. The new records and the new species provide valuable elements for the conservation of the highly threatened dry forests in Mexico and Sinaloa. |

Resumen Antecedentes y Objetivos: Durante exploraciones biológicas en el bosque espinoso cercano a las costas de Sinaloa, se colectaron especímenes de cuatro taxones no reportadas previamente para este estado, incluyendo el primer registro del género Castela, el cual se trató de una especie nueva para la ciencia. El objetivo de este trabajo fue describir e ilustrar a Castela juyyaania, así como reportar los tres nuevos registros adicionales para la flora de Sinaloa que comparten hábitat con la especie nueva. Métodos: Se realizaron colectas botánicas en el norte de Sinaloa durante 2022 y 2023. Para la descripción de la especie nueva se consultó la literatura disponible del género, ejemplares de herbarios y bases de datos electrónicas. Se elaboró una clave de identificación para la sección Castela en México, mapa de distribución, lámina comparativa con las especies más relacionadas y evaluación de vulnerabilidad de acuerdo con la Unión Internacional para la Conservación de la Naturaleza (UICN). Para los nuevos registros se presentan fotos y mapas de distribución actualizada. Resultados clave: Castela juyyaania es microendémica de la Península El Guachapori, en el norte de Sinaloa. Crece en bosque espinoso cercano a la costa, en un área de aproximadamente 25 km2, altamente amenazada por la expansión agropecuaria. De acuerdo con los criterios de la UICN, se propone en la categoría de Peligro Crítico. Se relaciona morfológicamente con el complejo C. erecta, de las que se diferencia por presentar hojas pecioladas, margen no conspicuamente revoluto, estilos presentes y semillas no reticuladas. El área de distribución presenta algunos elementos del desierto sonorense, incluyendo los nuevos registros Ebenopsis confinis, Gossypium davidsonii y Malpighia diversifolia. Conclusiones: Con la nueva adición, el género Castela llega a siete especies en México con cuatro endémicas, consolidándolo como su principal centro de diversidad. Los nuevos registros y la especie nueva aportan elementos valiosos para la conservación de los bosques secos altamente amenazados en México y Sinaloa.
