Additionally, four new species belonging to Atlantochodaeus are described: Atlantochodaeus everardoi n. sp. and Atlantochodaeus paulseni n. sp., both recorded from Rio de Janeiro State; Atlantochodaeus hucheti n. sp. from Espírito Santo, Minas Gerais, Rio de Janeiro, and São Paulo States, and Atlantochodaeus oliviae n. sp. from Minas Gerais State. Detailed descriptions of these species are accompanied by a differential diagnosis and a distribution map. A dichotomous key for all South American genera of Ochodaeidae and the species of Atlantochodaeus is provided to aid in identification. A comprehensive comparative morphology study regarding Parochodaeus pectoralis (LeConte, 1868) (type species of Parochodaeus) and the Atlantochodaeus species are discussed and illustrated. A discussion about gland, mycangium and stridulatory apparatus of Ochodaeinae are also provided. These findings emphasize the richness of the Atlantic Forest and underscore the importance of detailed taxonomic studies in revealing its biodiversity.en© The Author(s) 2025.
