description: Genus Atlantodesmus Hoffman, 2000
Atlantodesmus Hoffman, 2000: 102.
Type species: Leptodesmus eimeri Attems, 1898, by original designation.
Iemanja Hoffman, 2000: 106. Type species: I. teresa Hoffman, 2000, by original designation. Synonymized by Bouzan et al. 2017: 271.
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. 5C); presence of folds on the dorsal edge of the prefemoral region of the gonopod (Fig. 6B), 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).
Distribution
Occurring in the Atlantic rain forest (states of Paraná, Santa Catarina, São Paulo, Minas Gerais, Espírito Santo and Bahia) and in the Cerrado (states of São Paulo, Mato Grosso do Sul and Minas Gerais) areas of Brazil. See map in Bouzan et al. (2017).
Composition
Six species: Atlantodesmus eimeri (Attems, 1898), A. itapurensis (Schubart, 1943), A. pickeli (Schubart, 1946), A. pintoi (Schubart, 1946), A. teresa (Hoffman, 2000) and A. sierwaldae sp. nov.
