Etymology. The epithet is an adjective in Latin and refers to the shape of the process on the embolic disc ( Figs 20C View FIGURE 20 , 22A View FIGURE 22 , 23A View FIGURE 23 , 57F View FIGURE 57 ).

Diagnosis. Males of M. sinuosa   sp. nov. are most similar to those of M. wesolowskae   sp. nov., both with similar length of the embolic disc and PED ( Figs 20C View FIGURE 20 , 22A View FIGURE 22 , 23A View FIGURE 23 , 30C View FIGURE 30 , 32A View FIGURE 32 , 33A View FIGURE 33 , 57D, F View FIGURE 57 ). However, they differ by having a sinuous PED ( Figs 20C View FIGURE 20 , 22A View FIGURE 22 , 23A View FIGURE 23 , 57F View FIGURE 57 ), which is straight in M. wesolowskae   sp. nov. ( Figs 30C View FIGURE 30 , 32A View FIGURE 32 , 33A View FIGURE 33 , 57D View FIGURE 57 ). Also, M. sinuosa   sp. nov. can be distinguished from all currently known Marma   species by having the male palp with a thick RTA ( Figs 20D View FIGURE 20 , 22B View FIGURE 22 , 23 View FIGURE 23 D–E), being narrow (finger-shaped) in the other species ( Figs 30D View FIGURE 30 , 33E View FIGURE 33 , 36D View FIGURE 36 , 37B View FIGURE 37 ), and by having the copulatory openings fused into a single median opening ( Figs 21E View FIGURE 21 , 22G View FIGURE 22 , 24A, C View FIGURE 24 ).

Description. Male (Holotype, UFMG 13526). Total length: 2.96. Carapace 1.61 long, 1.04 wide, 0.85 high. Ocular quadrangle 0.78 long. Anterior eye row 1.08 wide, posterior 0.96 wide. Legs (3=4)12. Length of legs: I 2.49 (0.80 + 0.92 + 0.77); II 2.39 (0.77 + 0.90 + 0.72); III 3.10 (1.09 + 1.04 + 0.97); IV 3.10 (0.96 + 1.04 + 1.10).

Color in alcohol ( Figs 20 View FIGURE 20 A–B): cephalic area totally covered with scales; thoracic area with most concentration of scales in distal-central region; abdomen ventrally with thick longitudinal dark brown stripe; edge of thick dark stripe with pale circles; legs: femur I without dark marks, II with retrolateral surface with proximal and distal dark spot, III–IV with dark distal ring and proximal region with dark proventral spot; tibia I–II without dark marks, III with dark proximal ring, IV with dark proximal ring and distal region with prolateral and retrolateral dark spot; tarsus I almost black, II with black tip, III–IV with dark proximal ring.

Palp: RTA thick with narrow tip ( Figs 20D View FIGURE 20 , 22B View FIGURE 22 ); narrow embolic disc with straight prolateral border and sinuous retrolateral border ( Figs 20C View FIGURE 20 , 22A View FIGURE 22 ); PED sinuous ( Figs 22A, E View FIGURE 22 , 23A View FIGURE 23 ); base of embolus shaft large and bearing a prolateral lobe ( Figs 22C, E View FIGURE 22 , 23C View FIGURE 23 ); tip of embolus ends slightly beyond tip of PED ( Figs 22A, E View FIGURE 22 ); cymbium with retrodorsal depression ( Figs 20D View FIGURE 20 , 23D View FIGURE 23 ).

Female (Paratype, IBSP 87545). Total length: 3.01. Carapace 1.63 long, 1.10 wide, 0.78 high. Ocular quadrangle 0.77 long. Anterior eye row 1.08 wide, posterior 0.98 wide. Legs 3412.
