{"Abstract":["We report a dataset of all known and published occurrence records of animals of the phylum Rotifera, including Bdelloidea, Monogononta, and Seisonacea (with the exclusion of Acanthocephala) for Africa and surrounding islands and archipelagos. The dataset includes 27,225 records of 957 taxa (subspecies: 39; species: 819; genus: 81; family: 17; group: 1), gathered from 706 published papers. The published literature spans from 1854 to 2022, with the highest number of records in the decades 1990-1999 and 2010-2019. \n230 records of "species inquirendae", "nomina nuda", and "genera inquirenda" found in the published literature were not included in the dataset. Almost 90 % of the data are georeferenced.<\/p>\nThe African countries with the highest number of taxa are Nigeria, Algeria, South Africa, and Democratic Republic of the Congo, whereas no records are yet available for a dozen countries. The number of species known from each country can be explained mostly by sampling efforts, measured as the number of papers published for each country up to October 2022.<\/p>\nThis detailed literature search increased the number of known rotifer taxa at species, subspecies, form and variety level reported in previous reviews, which were 639 in 1986 (De Ridder, 1986) and 765 (Smolak et al., 2022) in 2022. Of the taxa reported in the current dataset, 167 (18%) are Bdelloidea, 665 (698%) Ploima, 97 (10%) Flosculariaceae, 27 (3%) Collothecacea and one representative of Seisonacea, the marine epizoic rotifer Seison africanus Sørensen, Segers & Funch, 2005 described and recorded only from coastal waters of Kenya (Sørensen et al., 2005).<\/p>\nThe data were structured based on the Darwin Core standard (Wieczorek et al., 2012). The dataset is structured to have in each row each record of a rotifer taxon from a sample from Africa and surrounding islands, as cited in the literature. The columns report the original and updated taxon name, additional taxonomic information together with origin of the data and habitat.\nAll invalid names (i.e. at the level of species inquirenda, nomen nudum, genus inquirendum) were not included in the records uploaded to GBIF. All names were also checked against the backbone of GBIF.<\/p>"]}
