Abstract The Atlantic Forest is known for its richness and diversity of species. Nonetheless, the diversity of millipedes in the biome is still poorly known. In this work, the distribution and the faunal composition of millipedes of the family Spirostreptidae Brandt, 1833 (order Spirostreptida) from the Atlantic Forest are provided. A total of 159 occurrence points were compiled, and 59 species in 17 genera were listed. GymnostreptusBrölemann, 1902 was recovered as the richest genus in the Atlantic Forest with 14 species and one subspecies. The species Plusioporus setiger (Brölemann, 1902) presented the highest number of records, with 22 occurrence points in at least 20 municipalities. A total of 35 species were recorded from only one municipality. Considering all the threats on the biome, this paper is important for our understanding of the Brazilian millipede fauna and can be useful to determine places that require valuations for collecting efforts and conservation policies.
