Abstract
Summary: A new species of Cumulopuntia (C. mollispina) is described and illustrated. The species is a narrow endemic from the Valley of the Rio Yauca, in the Department of Ayacucho near the frontier with the Department of Arequipa. It is known only from a small geographical area with a narrow elevation range of 1,700–1,800m. It is a member of the informal ‘Cumulopuntia sphaerica’ clade (=Sphaeropuntia Guiggi) but differs from all other members by growing as a hemispherical or slightly flattened cushion of tightly packed segments with soft flexible spination. We compare the new taxon with three other Cumulopuntia species: C. leucophaea, C. multiareolata and C. zehnderi, which all grow within 60km of C. mollispina. Zusammenfassung: Eine neue Cumulopuntia-Art, C. mollispina, wird beschrieben und abgebildet. Die Art ist ein enger Endemit aus dem Tal des Rio Yauca im Departamento Ayacucho nahe der Grenze zum Departamento Arequipa. Sie ist nur aus einem kleinen geografischen Gebiet mit einem schmalen Höhenbereich von 1700 bis 1800m bekannt. Sie gehört zur informellen Cumulopuntia sphaericaKlade (=Sphaeropuntia Guiggi), unterscheidet sich aber von allen anderen Vertretern durch ihren halbkugelförmigen oder leicht abgeflachten Polsterwuchs aus dicht gepackten Segmenten mit weicher, flexibler Bedornung. Wir vergleichen das neue Taxon mit drei anderen Cumulopuntia-Arten, C. leucophaea, C. multiareolata und C. zehnderi, die alle im Umkreis von 60km von C. mollispina wachsen.
