| description | Background and Aims: Amphilophium is a genus of Neotropical lianas belonging to the family Bignoniaceae, with a diversity of 47 species. Four species occur in Megamexico, which are morphologically characterized by hexagonal stems and capsular fruits with convex valves. The recent collections of Amphilophium in Veracruz state (Mexico) led to the identification of A. pilosum, previously reported only from Honduras. The present study aims to amend the morphological description and broaden the known distribution extension of A. pilosum.
Methods: Botanical material of Amphilophium pilosum from the dry forest of the central region in Veracruz State (Mexico) was collected and herborized. The population localized in the municipality Actopan was periodically visited to record the phenology of the species. Herbarium specimens of Amphilophium paniculatum throughout its distribution range, which is the most related species in morphological and phylogenetic terms, deposited in national and foreign herbaria, were examined in physical and digital collections. In addition, for comparative purposes, the specimens of all species of the genus with distribution in Megamexico were reviewed.
Key results: An amended description of Amphilophium pilosum is presented, accompanied by a complete illustration that includes the fruit for the first time, as well as details about the character states considered diagnostic for this species. Additionally, we include a dichotomous key and distribution maps for Amphilophium species distributed in Megamexico.
Conclusions: Mexico represents the northernmost country where Amphilophium pilosum is located. The record of this species increased the diversity of the genus Amphilophium in Mexico to five species, which highlights the importance of the taxonomic studies that focus on the biological diversity. |

Antecedentes y Objetivos: Amphilophium es un género de lianas neotropicales de la familia Bignoniaceae con una diversidad de 47 especies. En Megaméxico se localizan cuatro de ellas, las cuales morfológicamente se caracterizan por presentar tallos hexagonales y frutos capsulares con valvas de forma convexa. Colectas recientes de Amphilophium en el estado de Veracruz (México) derivaron en la identificación de A. pilosum, previamente reportada únicamente para Honduras. El objetivo de este trabajo es enmendar la descripción morfológica y presentar la ampliación del rango de distribución conocido de A. pilosum. Métodos: Se colectó y herborizó material botánico de Amphilophium pilosum en el bosque seco de la región central del estado de Veracruz en México. Se realizaron visitas periódicas para registrar la fenología de la especie en una población ubicada en el municipio Actopan. Se revisaron ejemplares botánicos depositados en herbarios nacionales y extranjeros de manera física y digital de Amphilophium paniculatum en todo su rango de distribución, la cual es la especie más afín en términos morfológicos y filogenéticos. Además, con fines comparativos, se revisaron los ejemplares de todas las especies del género con distribución en Megaméxico. Resultados clave: Se presenta una descripción enmendada de Amphilophium pilosum acompañada de una ilustración que incluye por primera vez el fruto y detalles sobre los estados de carácter considerados como diagnósticos para esta especie. Adicionalmente, se presenta una clave dicotómica y mapas de distribución para las especies de Amphilophium presentes en Megaméxico. Conclusiones: México representa el país más septentrional donde se encuentra Amphilophium pilosum. El registro de esta especie aumenta la diversidad del género en México a cinco especies, por lo que se resalta la importancia de continuar con los trabajos taxonómicos que documentan la diversidad biológica.
