Abstract
We present the first cumulative list of freshwater diatoms from Indonesia, encompassing literature extending from 1865 until 2023. A total of 1160 names have been published. With a consideration of homotypic synonyms, the total number of different freshwater diatom taxa reported from Indonesia is over 1050. Genera with the largest number of reported species include Nitzschia (94), Cymbella sensu lato (73), Eunotia (72), Pinnularia (67), Surirella (60), and Gomphonema (48). There are two genera endemic to Indonesian freshwaters, namely Alveocymba and Celebesia, while all but one species of Tetralunata are endemic. Over 30% of the reported taxa are endemic to Indonesia. The flora of Indonesia is similar in size to that reported for all of Europe. The reported freshwater diatom flora of Indonesia, with the desmid flora, when combined, surpasses the number of all other algae reported for Indonesia.
