Diagnosis. Males of Atlantodesmus teresa differ from other species of the genus by the acropodite process covering the solenomere in almost its entire length, in mesal ( Fig. 16 A) and ectal ( Fig. 16 B) views.

Redescription. Male (UFPI 014). Coloration (in alcohol): Head dark brown. Body dark brown. Paranota same color as body. Telson brown. Total length: 74. Collum 3.32 long, 12.56 wide. Antennomere lengths (1>7): 0.73; 2.72; 3.06; 2.75; 2.35; 1.99; 0.25. Gonopod aperture 3.73 long, 2.22 wide. Telson 1.62. Coxae with a row of bristles in the distal dorsal side. Coxal apophysis small. Prefemoral region ventrally positioned and gradually narrowing to tip. Prefemoral process forms a long narrow blade with an acuminate apex ( Fig. 17 D). The dorsal side of the prefemoral region with several folds. Conspicuous cingulum present ( Fig. 17 C). Solenomere long, with pointed tip. Acropodite process covering the solenomere in most of its length, the laminate apex overreaching the solenomere ( Fig. 17 D).

Female (IBSP 4106). Coloration (in alcohol): Head reddish. Body brown. Paranota tip with the same color as the body. Legs reddish. Telson brown. Total length 70.43. Collum 3.17 long, 10.88 wide. Telson 1.88. Antennomere lengths (1>7): 0.52; 2.44; 2.45; 2.26; 2.13; 1.78; 0.19. Cyphopods ( Figs 18 C–D) densely setose. The apical part of cyphopod is projected and pointed, the intermediate membrane is contained between the valves ( Fig. 18 C).

Distribution. States of Minas Gerais and Espírito Santo, Brazil, in areas containing the Brazilian biome Atlantic forest ( Por et al. 2005).
