Leptodesmus pickeli Schubart, 1946: 166 View in CoL , fig. 1 (Male holotype, originally recorded as Bairro da Casa Verde, São Paulo, however the correct location is Jardim São Bento, São Paulo (46°38′ 0″ W, 23°33′ 0″ S) GoogleMaps , São Paulo, Brazil; 1939, Dom B. J. Pickel leg., deposited in IBSP 29 View Materials , examined).

Diagnosis. Males of Atlantodesmus pickeli differ from all other species of the genus by the presence of a small triangular lobe above the base of the solenomere ( Fig. 12 View FIGURE 12 A, arrow) and prefemoral process densely serrated in its distal part ( Figs 12 View FIGURE 12 A–B).

Additional material examined. None.

Redescription. Male (Holotype, IBSP 29). Coloration (in alcohol): Head reddish brown. Body dark brown. Paranotal tips yellow. Telson brown. Total length: 60. Collum absent. Antennomere lengths (1>7): 0.97; 2.32; 2.20; 1.95; 2.18; 1.60; 0.31. Gonopod aperture 3.14 long, 3.87 wide. Telson missing. Gonopods: coxae with two bristles on the distal dorsal side. Coxal apophysis not acute. Prefemoral region ventrally positioned. Prefemoral process long, narrow in the base and dilated at its apex, with densely serrated margins ( Fig. 12 View FIGURE 12 A). Reduced cingulum present ( Fig. 12 View FIGURE 12 B). Solenomere tip acute. Triangular lobe above the base of the solenomere, visible in mesal view ( Fig. 12 View FIGURE 12 A, arrow). Acropodite process forming a large hood, with serrated distal mesal margin ( Figs 12 View FIGURE 12 A–B).

Female (IBSP 4433). Coloration (in alcohol) and body as in male. Total length 60. Collum 2.59 long, 8.08 wide. Telson 1.80.

Distribution. Known only from the city of São Paulo, São Paulo, Brazil, in areas containing the Brazilian biome Atlantic forest ( Por et al. 2005).
