Diagnosis. Adults males of Rupidesmus ruber  differ from those of R. aclys  n. sp. based on combination of gonopodal characteristics: Prefemoral process directed diagonally in relation to acropodite ( Fig. 3AView FIGURE 3). Prostatic groove running marginally on acropodite, with a basal curvature and a sinuous distal curvature ending upon a short prostatic apex ( Fig. 3AView FIGURE 3). Indention located distal to a bulky tab; tab curving ventrally imparting a twisted shape ( Figs. 3A, BView FIGURE 3). Presence of a rounded ventral tip on acropodite ( Fig. 4FView FIGURE 4).

Redescription. Male (Holotype, MZSP 996). Coloration in life, of the specimens described by Schubart (1952), reddish brown (when viewed just before preservation). Coloration (fixed in 70% ethanol): Head ochre. Body light ochre. Paranota tip a little lighter than the color of the body. Legs yellow. Telson ochre. Sternites of body rings 5 to 17 with two pairs of rounded projections between the coxae ( Fig. 5FView FIGURE 5, arrows). Total length: 60.6. Collum 3.27 long, 8.02 wide. Antennomere lengths (1>7): 1.05; 1.89; 1.69; 1.60; 1.78; 1.64; 0.40. Gonopod aperture ( Fig. 5EView FIGURE 5) 1.85 long, 3.08 wide. Telson 1.35 long. Gonopods ( Figs 3A –CView FIGURE 3, 4View FIGURE 4): coxae with two setae on distal dorsal side and with a row of setae on distal ventral side. Spiniform process present on gonocoxae (SP; Fig. 3BView FIGURE 3). Prefemoral region short, 1/4 length of telopodite. Prostatic groove with a basal curvature and a sinuous distal curvature ending upon a short prostatic apex. Prefemoral process small, dagger-shaped and directed diagonally in relation to acropodital branch (PfP; Figs 3AView FIGURE 3, 4DView FIGURE 4). Acropodite flat and massive (A; Figs 3A –CView FIGURE 3), middle part with prominent indentation just distal to a tab at posterior margin which continues to anterior margin ( Figs. 3A, BView FIGURE 3, arrow). Posterior margin in apical region with a rounded acropodital process (AP; Figs 4A, FView FIGURE 4), acropodite ending upon a short prostatic apex ( Figs 4A –B, FView FIGURE 4).

Female ( MZSP 999). Coloration (in 70% ethanol) as in male. Total length 63.7. Collum 3.72 long, 8.10 wide. Telson 1.79 long. Cyphopods ( Figs 5A –BView FIGURE 5) with thick setae dispersed over the whole of the valves. Apical part of cyphopod concave, with the intermediate membrane projecting between the valves ( Fig. 5AView FIGURE 5).

Distribution. Known only from the state of Minas Gerais, in the southeast portion of the limestone karst Bambui Group.
