A spatial inventory of freshwater macroinvertebrate occurrences in the Guineo-Congolian biodiversity hotspot

We collated species occurrence records of freshwater invertebrates across the Guineo-Congolian region and present a dataset of 8,809 occurrences consisting of 4 phyla, eight classes, 32 orders, and 1,104 species. We added also the Hydrography90m stream network attributes to the macroinvertebrate occurrence records, such that the data spans across 2,890 catchments and stream orders 1-12. These records are considered valid and can be used for biogeographic analysis of freshwater macroinvertebrates in this important yet understudied freshwater biodiversity hotspot.
