Figs 18D–18F , 20A–20D , 21A–21E

Type material. Holotype: ♂ from Pico do Sol , Santuário do Caraça , Reserva Particular do Patrimônio Natural, Santa Barbara, Minas Gerais, Brazil (20.059°S, 43.505°W), 7.X.2010, L.N Perillo leg. (UFMG 6606).

Etymology. The epithet, to be treated as a noun in apposition, is due to the embolus and paraembolic apophysis reminiscent of the sign for “okay ” in LIBRAS, the Brazilian Sign Language.

Diagnosis. The male of R. okay sp. nov. differs from all other known species of Rhyphelia by having an apophysis projecting from the base of the embolus towards the apex of the cymbium ( Fig. 21A ). The female is similar to those of R. otti sp. nov. and R. ruizi for the narrow coupling pocket on the epigyne ( Fig. 21C ), but differs by the shorter copulatory ducts (loops close to spermathecae).

Leg formula: 4132; length of legs: I 3.66 (1.15 + 0.62 + 0.93 + 0.60 + 0.36), II 2.93 (0.96 + 0.48 + 0.60 + 0.53 + 0.36), III 3.56 (1.1 + 0.54 + 0.77 + 0.79 + 0.36), IV 3.80 (1.15 + 0.48 + 0.81 + 0.93 + 0.43). Legs coloration: femora, patellae, tibiae and metatarsi dark brown, tarsi yellow. Tibia I macrosetae well developed, with tips close together. Abdomen, dorsally dark brown with a pattern of transverse clear markings ( Fig. 20A ); ventrally dark brown. Spinnerets dark brown.

Female paratype. Total length: 3.57. Carapace dark brown ( Fig. 20C ); 1.75 long, 1.2 wide, 0.91 high. Ocular quadrangle 0.84; anterior eye row 1.29, posterior 1.15 wide. Chelicera, labium, endite and sternum dark brown ( Fig. 20D ). Palp yellow. Leg formula: 4=312; length of legs: I 3.26 (1.01 + 0.48 + 0.84 + 0.57 + 0.36), II 2.60 (0.86 + 0.38 + 0.55 + 0.45 + 0.36), III 3.40 (1.01 + 0.48 + 0.79 + 0.74 + 0.38), IV 3.40 (1.01 + 0.43 + 0.79 + 0.74 + 0.43). Legs yellow. Macrosetae as in male.Abdomen dorsally dark brown with cream-colored transverse bar at middle and chevrons; ventrally yellow. Egipyne with circular copulatory openings and reniform spermathecae ( Figs 21C–E ).
