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, 15A, 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, 9C, 15E, 16A). 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, 15G, 58B), 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, 7H, 58A). Also, females of M. linae sp. nov. have homogeneous primary spermathecae with distal portion projecting anteriorly (Figs 14 C–D, 15F–G, 58B), whereas primary spermathecae have di l ated initial portion, tapering towards fertilization ducts in M. baeri (Figs 6C, 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.

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