Anathallis manausensis (Orchidaceae, Pleurothallidinae), a new species from the Brazilian Amazon

Abstract

A new species is proposed in the genus Anathallis. It is described, illustrated and compared with its relatives. A key to the Amazonian species of Anathallis is presented. We propose a new combination in the genus Lankesteriana.

A new species of Anathallis (Orchidaceae: Pleurothallidinae) from Brazil

“…However, these figures include a number of species recently transferred to Stelis Sw. (Chiron, Guiard & van den Berg 2012, Karremans 2014 and to Lankesteriana Karremans (Karremans 2014(Karremans , 2015. Following this narrower concept and including the new species described herein, some recent additions not yet listed in Brazilian Flora 2020 (Chiron, Guiard & Bolsanello 2013, Krahl et al 2016 and excluding a number of obscure names and synonyms, the current accepted Anathallis names for the Brazilian flora is approximately 72 species.…”

<i>Catasetum tavaresii</i> (Catasetinae), a new species from Central Brazilian Amazon

“…The genus is restricted to the Neotropical region, where it is widely distributed, occurring from Mexico to Southern Brazil and Northern Argentina (Romero & Carnevali 2009). The Amazonian biome is considered the center of diversity for the genus (Romero & Carnevali 2009) and the Brazilian Amazon is particularly noteworthy, hosting a total of 77 species (Krahl et al 2021a,b, 2022a,b, 2023a,b,c,d, Petini-Benelli 2023, Petini-Benelli & Chiron 2020, Valsko et al 2019, in addition to housing rare species of the genus (Krahl et al 2023e).…”

“…The state of Pará, the second largest Brazilian state entirely located in the Brazilian Amazon, houses a total of 32 Catasetum species, accounting for approximately 40% of the Amazonian and Brazilian species (Krahl et al 2021a,b, 2022a,b, 2023a,d, Petini-Benelli 2023. Therefore, this work aims to increase the species richness of the state of Pará by describing a new taxon of Catasetum from the extreme west of the state.…”
