3809A3436E06FFF3FDBFF8FDFA9BFCD7.taxon	diagnosis	Diagnosis Modified from Bouzan et al. (2017): males of Atlantodesmus differ from other chelodesmid genera by the combination of the following characters: absence of ventral projections on the sternites (except A. itapurensis and A. teresa, which have a pair of projections on the fourth sternite; Fig. 5 C); presence of folds on the dorsal edge of the prefemoral region of the gonopod (Fig. 6 B), except A. pickeli; presence of a cingulum (Fig. 2 E−F); acropodite branching, forming a long, thin, falciform solenomere, and a large acropodite process with a broadened apical region overreaching the tip of the solenomere (Fig. 2 C−F).	en	Bouzan, Rodrigo Salvador, Iniesta, Luiz Felipe Moretti, Brescovit, Antonio Domingos (2019): Cladistic analysis and description of a new species of the Brazilian genus Atlantodesmus Hoffman, 2000 (Diplopoda: Polydesmida: Chelodesmidae).
