Abstract
A new species from the montane forests in central Peru belonging to the Pteroidea clade of Solanum is described and illustrated. Solanum stellaticalycinum M. A. Cueva, Treviño & D. Sotomayor, sp. nov. is known only from the Yanachaga-Chemillén National Park and adjacent areas (Prov. Oxapampa, Dept. Pasco, Peru). With simple leaves, it is morphologically similar to S. anceps Ruiz & Pav., a widespread species in South America, and to S. angustialatum Bitter and S. incurvum Ruiz & Pav., both known from the montane forests of northern and central Peru. Solanum stellaticalycinum is distinguished from all these by its purple pedicels and flowers with linear to narrowly triangular calyx lobes, a membranous corolla with lanceolate lobes and ovoid-conical, smooth or slightly rugose fruits. Here we discuss the taxonomic affinities, distribution and conservation status of this new species. We also include a key to all species of Pteroidea with complete distributions at the country level and department level distributions within Peru.
