Note. The original description and figures by Attems (1898), as well the descriptions by Schubart (1954), are highly detailed, making the examination of the type material unnecessary. Also, specimens of A. eimeri  were easily identified among collections, due to its distinct gonopod and unusual tubercles in the dorsal surface of the metazonites, thereby allowing a more comprehensive analysis.

Diagnosis. Males differ from all other species of the genus by the acropodite process not enveloping the solenomere ( Fig. 7View FIGURE 7 A), by presence of a well-defined coxal apophysis in the gonopod ( Fig. 8View FIGURE 8 A, arrow) and dorsal surface of the diplosegments with conspicuous tubercles ( Fig. 7View FIGURE 7 D).

Redescription. Male ( IBSP 4367). Coloration (in alcohol): Head reddish brown. Body reddish brown. Paranota tip with the same color as the body. Legs reddish. Telson brown. Total length: 42.4. Collum 1.43 long, 5.07 wide. Antennomere lengths (1>7): 0.69; 1.63; 1.16; 1.05; 1.36; 1.43; 0.40. Gonopod aperture 1.09 long, 1.65 wide. Telson 1.07. Gonopods: coxae with a distal row of bristles dorsally. With a coxal apophysis ( Fig. 8View FIGURE 8 A). Prefemoral region ventrally positioned. Prefemoral process long, reaching approximately the apex of the solenomere. Apex of the prefemoral process spatula-shaped with a serrated margin ( Fig. 7View FIGURE 7 A). Dorsal side of prefemoral region with several folds. Cingulum reduced ( Fig. 7View FIGURE 7 C). Solenomere elongated and sickle-shaped. Acropodite process flat, blade-shaped, not enveloping the solenomere ( Figs 7View FIGURE 7 A –B).

Female (IBSP 2332). Coloration (in alcohol) and body as in male. Total length 41. Collum 1.83 long, 5.42 wide. Telson 1.13. Cyphopods ( Figs 8View FIGURE 8 C –D) with thick bristles dispersed on each of the valves. Apical part of cyphopod concave, with the intermediate membrane projecting between the valves ( Fig. 8View FIGURE 8 D). Distribution. States of Paraná and Santa Catarina, Brazil, in areas containing the Brazilian Atlantic forest biome ( Por et al. 2005).
