Etymology. The species is named after the Brazilian arachnologist Lina Maria Almeida Silva, the first to bring us specimens of this species from Bahia, Brazil.

Diagnosis. Males of M. linae  sp. nov. are most similar to those of M. baeri  , both with a short process on the embolic disc (PED), but they differ by having a thinner embolic disc ( Figs 7AView FIGURE 7, 15AView FIGURE 15, 57View FIGURE 57 A–B). Besides, the embolus in M. linae  sp. nov. emerges from a more proximal portion of the embolic disc, and consequently is longer than in M. baeri  (best visualized after clarification techniques using clove oil; Figs 7FView FIGURE 7, 9CView FIGURE 9, 15EView FIGURE 15, 16AView FIGURE 16). Females of M. linae  sp. nov. differ by having the copulatory openings close together and aligned with the distal portion of primary spermathecae ( Figs 14CView FIGURE 14, 15GView FIGURE 15, 58BView FIGURE 58), whereas they are separated by approximately three times the girth of the copulatory duct and placed anterior to the primary spermathecae in M. baeri  ( Figs 6CView FIGURE 6, 7HView FIGURE 7, 58AView FIGURE 58). Also, females of M. linae  sp. nov. have homogeneous primary spermathecae with distal portion projecting anteriorly ( Figs 14View FIGURE 14 C–D, 15F–G, 58B), whereas primary spermathecae have di l ated initial portion, tapering towards fertilization ducts in M. baeri  ( Figs 6CView FIGURE 6, 7View FIGURE 7 G–H, 58A).

Description. Male (Holotype, MPEG 34356). Total length: 4.08. Carapace 2.09 long, 1.37 wide, 1.02 high. Ocular quadrangle 0.84 long. Anterior eye row 1.33 wide, posterior 1.10 wide. Legs 1342. Length of legs: I 5.20 (1.56 + 2.02 + 1.62); II 3.73 (1.17 + 1.34 + 1.22); III 4.42 (1.44 + 1.48 + 1.50); IV 4.29 (1.34 + 1.42 + 1.53).

Tibia I p0-1-0, r0, v2-2-2; II p0-1-0, r0-1-0, v1r-2-2; III p0-1-1-0, r1-1-1-0 (or 0-1-1-0), v1p-0-0-2; IV p0-1-1-0, r1-1-1-0, v1p-0- 0-2; Metatarsus I p1di, r0, v2-2; II p1-1, r1di, v2-2; III d1p-0-0, p1-0-2, r1-0-2, v2-0-2; IV p1-1-2, r1-1-2, v1p-0-2 (or v2-0-2).

Color in alcohol ( Figs 13View FIGURE 13 A–B): scales uniformly distributed on carapace; abdomen ventrally pale; legs: femur I with dark distal ring and with prolateral and retrolateral dark stripe, II with dark distal ring and with proximal region with prolateral and retrolateral dark spot, III with dark distal ring and proximal region with dark proventral spot, IV with dark distal ring and proximal region with dark prolateral spot; tibia I–II without dark marks, III–IV with proximal and distal dark ring; tarsus I totally black, II without dark marks, III–IV with dark proximal ring.

Palp: RTA finger-shaped ( Figs 13View FIGURE 13 C–D); thin embolic disc with both edges straight ( Figs 13CView FIGURE 13, 15AView FIGURE 15); PED approximately with same length of exposed portion of embolic disc, emerging from prodistal part of embolic disc ( Figs 15A, EView FIGURE 15); tip of embolus ending more distally than tip of PED ( Figs 13CView FIGURE 13, 15AView FIGURE 15).

Female (Paratype, MPEG 34346). Total length: 3.62. Carapace 1.85 long, 1.19 wide, 0.88 high. Ocular quadrangle 0.80 long. Anterior eye row 1.21 wide, posterior 0.98 wide. Legs (4=3)12. Length of legs: I 2.84 (0.93 + 1.04 + 0.87); II 2.72 (0.91 + 0.98 + 0.83); III 3.78 (1.29 + 1.29 + 1.20); IV 3.78 (1.18 + 1.26 + 1.34).

Leg macrosetae: femur I d1-1-1, p1di, r0; II–III d1-1-1, p1di, r1di; IV d1-1-1, p0, r1di; patella I–II 0; III–IV p0, r1; tibia I–II p0-1-0, r0, v1r-2-2; III p1-1-1-0 (or p0-1-1-0), r0-1-1-0 (or r1-1-1-0), v1p-0-0-2; IV p0-1-1-0, r1-1-1- 0, v1p-0-0-2; metatarsus I p1di, r0, v2-2; II p1-1, r1di, v2-2; III d1p-0-0, p1-0-2, r1-0-2, v2-0-2; IV p1-1-2, r1-1-2, v1p-0-2.

Color in alcohol ( Figs 14View FIGURE 14 A–B): carapace and abdomen as in male; legs: femur I–II with dark distal ring and proximal region with prolateral and retrolateral dark spot, III–IV with dark distal ring and proximal region with dark prolateral spot; tibia I–IV with dark proximal ring and distal region with prolateral and retrolateral dark spot; tarsus I–II without dark marks, III–IV with dark proximal ring.

Epigyne ( Figs 14View FIGURE 14 C–D, 15F–G, 17A–D): copulatory openings separated by less than 1/2 their diameter, placed at same level as primary spermathecae; copulatory ducts very short; proximal copulatory duct slighty shorter than distal section; primary spermathecae with homogenous diameter and anteriorly projected.
