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 7A View FIGURE 7 , 15A View FIGURE 15 , 57 View 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 7F View FIGURE 7 , 9C View FIGURE 9 , 15E View FIGURE 15 , 16A View 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 14C View FIGURE 14 , 15G View FIGURE 15 , 58B View 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 6C View FIGURE 6 , 7H View FIGURE 7 , 58A View FIGURE 58 ). Also, females of M. linae   sp. nov. have homogeneous primary spermathecae with distal portion projecting anteriorly ( Figs 14 View FIGURE 14 C–D, 15F–G, 58B), whereas primary spermathecae have di l ated initial portion, tapering towards fertilization ducts in M. baeri   ( Figs 6C View FIGURE 6 , 7 View 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 13 View 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 13 View FIGURE 13 C–D); thin embolic disc with both edges straight ( Figs 13C View FIGURE 13 , 15A View FIGURE 15 ); PED approximately with same length of exposed portion of embolic disc, emerging from prodistal part of embolic disc ( Figs 15A, E View FIGURE 15 ); tip of embolus ending more distally than tip of PED ( Figs 13C View FIGURE 13 , 15A View 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 14 View 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 14 View 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.
