Abstract

A revision of the dioecious genus Chersodoma (Senecioneae, Asteraceae) recognizes nine species, including a new species, C. deltoidea Sagást. & M. O. Dillon, from northern Peru and a status change for a northwestern Argentine endemic, C. glabriuscula (Cabrera) M. O. Dillon & Sagást. Chersodoma is confined to the Andean Cordillera and is the only dioecious member of the Senecioneae in continental South America. A cladistic analysis of a morphological data set supports the monophyly of the genus and the recognition of two previously established subgenera. Subgenus Chersodoma contains three species (C. argentina, C. candida, C. jodopappa) with greatest diversity in the semi-arid puna of northwestern Argentina and adjacent Bolivia and Chile. Subgenus Diclinanthus B. Nord., contains six species (C. antennaria, C. arequipensis, C. deltoidea, C. juanisernii, C. glabriuscula, and C. ovopedata) with greatest diversity in Peru. A key to Andean genera of Senecioneae is provided. A discussion of species relationships and historical biogeography is presented as suggested by morphological parsimony analysis.

Resumen

Se presenta la revisón del género dioico Chersodoma (Senecioneae, Asteraceae) que consta de nueve taxa, incluyendo una nueva especie del norte del Perú: C. deltoidea Sagást. & M. O. Dillon y el cambio de status de una especie endémica del noroeste de Argentina: C. glabriuscula (Cabrera) M. O. Dillon & Sagást. Chersodoma está confinado a la Cordillera Andina y es el único género dioico de Senecioneae en Sudamérica continental. El análisis cladístico de sus caracteres morfológicos nos permite afirmar que es un género monofilético y reconocer sus dos subgéneros previamente establecidos: el subgénero Chersodoma que consta de tres especies (C. argentina, C. candida, C. jodopappa) con gran diversidad en la zona semiárida de la Puna del noroeste de Argentina y áreas adyacentes de Bolivia y Chile y el subgénero Diclinanthus B. Nord. que contiene seis especies (C. antennaria, C. arequipensis, C. deltoidea, C. juanisernii, C. glabriuscula, y C. ovopedata) con gran diversidad en el Perú. Se provee de una clave para los géneros andinos de Senecioneae y se discuten las relaciones y la historia biogeográfica de las especies de acuerdo a la sugerencia de los resultados del análisis morfológico.
