Diagnosis.Males of Atlantodesmus pintoidiffer from all other species of the genus by the acropodite process with a large, rounded spoon-shaped tip ( Figs 13A–B, 14A–B).
Redescription. Male( Holotype, MZSP 412). Coloration (in alcohol): Head reddish brown. Body brown with a median dorsal white band. Paranota tip white. Legs reddish. Telson white. Total length: 57. Collum 2.09 long, 7.11 wide. Antennomere lengths (1>7): 0.91; 2.40; 2.28; 2.20; 2.20; 1.78; 0.29. Gonopod opening: 1.21 long, 1.78 wide. Telson 1.95. Gonopods: coxae with two bristles in the distal dorsal side. Without coxal apophysis. Prefemoral region ventrally positioned. Prefemoral process long, with narrow stalk about half of total PfP length; apex expanded, calyx-shaped, edge of calyx slightly serrated ( Fig. 13A). The dorsal side of the prefemoral region with several folds ( Fig. 14D). Transition from prefemoral region to acropodite discontinuous. Small incision at the external margin of the telopodite is visible in mesal view. Reduced cingulum visible in ectal view ( Fig. 14C, arrow). Solenomere long and falciform. Acropodite process with a rounded lobe above the base of the solenomere ( Fig. 13A, arrow), acropodite process terminating in a large flat rounded apex ( Figs 13A–B). Female( Paratype, MZSP 929). Coloration (in alcohol) and body as in male. Total length 50. Collum 2.03 long, 6.80 wide. Telson 1.83. Cyphopods ( Figs 15B–D) with numerous dispersed fine bristles on both valves. The apical part of cyphopod is slightly projected, the intermediate membrane projects between the valves ( Fig. 15B). Variation: The body of some specimens can show a whitish yellow coloration, however the median band is present, but weakly developed. In some individuals the apex of the prefemoral process lacks serration.
Distribution.State of Bahia, Brazil, in areas containing the Brazilian Atlantic forest biome ( Por et al.2005).
