New species and species diversity of Desmodesmus (Chlorophyceae, Chlorophyta) in Saga City, Japan
Abstract Desmodesmus spp. are one of the most dominant components of phytoplankton, which are present in most water bodies. However, identification of the species based only on morphological data is challenging. The aim of the present study was to provide a comprehensive understanding of the actual...

| description | Abstract Desmodesmus spp. are one of the most dominant components of phytoplankton, which are present in most water bodies. However, identification of the species based only on morphological data is challenging. The aim of the present study was to provide a comprehensive understanding of the actual distribution of the Desmodesmus species in Saga City, Saga Prefecture, Japan. In the present study, 38 water bodies were surveyed between June 2017 and March 2023. A total of 86 culture strains were established from the samples collected from the 21 sites, and identified by molecular phylogenetic analysis, comparison of ITS2 rRNA secondary structures, and observation of surface microstructure. In total, four new species, including D. notatus Demura sp. nov., D. lamellatus Demura sp. nov., D. fragilis Demura sp. nov., and D. reticulatus Demura sp. nov. were proposed and 17 Desmodesmus species were identified as described species. The present study revealed > 20 Desmodesmus species, exhibiting high genetic diversity in a small area. |
