[Botany • 2021] Catasetum kamatawara (Orchidaceae: Catasetinae) • A New Species, Lectotypification and New Records in Catasetum from Peruvian Amazon

Catasetum kamatawara Damián, Mitidieri & Bonilla

in Damián, Mitidieri, Bonilla & Huayllani, 2021.
We describe and illustrate Catasetum kamatawara from the Loreto Department of the Amazonian wetlands in Peru. An extensive comparison with several related species is presented including Catasetum cotylicheilum which is morphologically close to our species but differs mainly in having a three-lobed labellum with a three-dentate apex formed by its obtuse apices of lateral lobes and mid-lobe (vs. unlobed labellum with obtuse-rounded apex), and the presence of 4–5 transversely verrucose keels (vs. elevated, smooth callus). Additionally, we also report C. boyi, C. longifolium and C. semicirculatum which have not been previously reported for the Peruvian orchid flora. Finally, we propose a lectotype for the rare C. peruvianum based on the original illustration of the species.

Etymology: The specific epithet makes references to the Niapitsara kamatawara Conservation Association based in Parinari (Loreto), which aims to conserve the Amazonian wet-lands called “aguajales”, dominated by the palm Mauritia flexuosa (aguaje). Members of this association belong to Kukama-Kukamiria, an indigenous Amazonian commu-nity which inhabits inside the basin of the Marañon, Huallaga, Ucayali, and Amazonas rivers. The language of Kukama-kukamiria is known by the same name and reflects the deep knowledge of animals and plants of their territories including at least 120 terms for birds, more than 100 for fish, and 25 referring to various species of palms (Vallejos and Amias 2015). The term “niapitsara kamatawara”, after which the association is named, means “working man”. According to the Peruvian Ministry of Culture, the Kukama-kukamiria language is at high risk of extinction due to its currently low rate of native speakers. Therefore, the epithet chosen is an attempt to revive the traditional use of this ancestral language.
