The new cyanobacterial species Cyanoarbor violascens was found and described from subaerophytic habitats (wet lateritic soils) in the northwest region of São Paulo State, Brazil. The phenotypic generic features of the population were confirmed and the genus Cyanoarbor Wang 1989 was revised with four species recognized. Cyanoarbor rupestris Wang was first described from subaerophytic habitats in China. Cyanoarbor violascens Branco sp. nov. is here described from subaerophytic habitats (wet lateritic soils) in the northwest region of São Paulo State, Brazil, differing from other species by violet-coloured sheaths, cell sizes and ecotopic preference. Additionally, material previously identified as Chlorogloea cf. microcystoides from Nepal was recognized as belonging to Cyanoarbor and is here described as C. himalayensis M. Watanabe et Komárek sp. nov. Chlorogloea gessneri Schiller is transferred to the genus Cyanarbor, as C. gessneri (Schiller) nov. comb. All four species can be differentiated based on a combination of morphological characters and biotopic preferences. Descriptions and an identification key of the four species of this genus are provided.

Cyanoarbor violascens é uma nova espécie de cianobactéria encontrada e descrita a partir de material subaéreo (solos lateríticos úmidos) encontrado na região noroeste do estado de São Paulo, Brasil. As caracterísitcas genéricas da população foram confirmadas e o gênero Cyanoarbor Wang 1989 foi revisado, considerando-se quatro espécies. Cyanoarbor rupestris Wang foi descrito em habitats subaerofíticos da China. Cyanoarbor violascens Branco sp. nov. é aqui descrita com base em material coletado em habitats subaerofíticos (solos lateríticos úmidos) na região noroeste do estado de São Paulo State, Brasil, diferenciando-se de outras espécies pelas bainhas violetas, dimensões celulares e ecologia. Adicionalmente, material previamente identificado como Chlorogloea cf. microcystoides do Nepal foi considerado pertencente ao gênero Cyanoarbor e é aqui descrito como C. himalayensis M. Watanabe et Komárek sp. nov. Chlorogloea gessneri Schiller é transferida para Cyanoarbor gessneri (Schiller) nov. comb. Todas as espécies consideradas podem ser diferenciadas pela combinação de caracteres morfológicos e ecológicos. São apresentadas as descrições das quatro espécies, bem como uma chave para identificação.
