Type material. Holotype: MARTINIQUE: Marin : ♂, Martinique [14.5390, ‑61.0361], 8–21 June 2013, A. Sanchez leg. ( IBSP 271305 View Materials ) GoogleMaps . Paratypes: MARTINIQUE: 1♀, Anse Mitan [14.5390, ‑61.0361], Trois Ilets, 10–11 June 1960, C. & P. Vaurie leg. ( AMNH) GoogleMaps ; GUADELOUPE: Basse-Terre : 1♀, Matouba [16.0403, ‑61.6902], 1 July 1960, C. & P. Vaurie leg. ( AMNH) GoogleMaps .

Additional material examined. DOMINICA: Saint George: 1♀, Fresh Water Lake (NE of Laudat) [15°20’39.04”N, 61°18’38.33”W], 22 March 1956, I.F.G. Clarke leg. ( USNM) GoogleMaps ; Saint Luke: 1♀, South Chiltern [Estate] (N of Soufrière) [15°15’8.72”N, 61°21’32.09”W], 25 March 1964, D.F. Bray leg. ( USNM) GoogleMaps .

Etymology. The specific name refers to the type locality of the holotype; noun in apposition.

Diagnosis. Males of M. martinique spec. nov. resemble those of M. abuna spec. nov. ( Figs 103–106 View FIGURES 103–106 ) by the palp with embolus bearing small, tubercle-like subdistal projection and large membranous area ( Fig. 199 View FIGURES 196–202 ). They are distinguished from the latter species by the PTA triangular, RTA abruptly narrowed medially and embolus without prolateral bulge at base ( Figs 196–198 View FIGURES 196–202 ) (PTA distally rounded, RTA gradually tappering and embolus bulging prolaterally at base in M. abuna spec. nov.). Females resemble those of M. trinitatis comb. nov. ( Figs 269–274 View FIGURES 269–274 ) and M. tumatumari spec. nov. ( Figs 280–282 View FIGURES 280–282 ) by the vulva with GP arising from ducts close to spermathecae, not at first turn. They are distinguished from both species by the MS subrectangular, with lateral margins medially constricted ( Fig. 200 View FIGURES 196–202 ) (MS widest medially with lateral margins not constricted in M. trinitatis and M. tumatumari spec. nov.).

Description. Male (holotype): Total length 11.3. Prosoma 5.4 long, 5.3 wide. Opisthosoma 5.8 long, 3.6 wide. Eyes: diameters: 0.41, 0.36, 0.25, 0.35; interdistances: 0.25, 0.10, 0.45, 0.50, 0.33, 0.20. Legs: I: 31.2 (8.6, 3.2, 8.4, 8.8, 2.2); II: 33.8 (9.4, 3.3, 9.4, 9.5, 2.2); III: 21.8 (6.5, 2.8, 5.5, 5.4, 1.6); IV: 24.1 (7.2, 2.4, 6.2, 6.4, 1.9). Spination follows the generic pattern except tibia III: d1-0-1, tibia IV: d0; metatarsus IV: r1-1-2. Palp: PTA as wide as long; RTA roughly 2 times longer than wide (retrolateral view); cymbium with small retroproximal projection; subtegulum visible between 9–10 o’clock in ventral view; tegulum slightly projectiong over conductor base; conductor widest at base, distally fanned embolus subdistally curved ( Figs 196–199 View FIGURES 196–202 , 203–205 View FIGURES 203–207 ).

Female (paratype, Guadeloupe): Total length 17.8. Prosoma 7.1 long, 7.2 wide. Opisthosoma 10.2 long, 6.2 wide. Eyes: diameters: 0.51, 0.45, 0.35, 0.42; interdistances: 0.37, 0.31, 0.65, 0.72, 0.40, 0.25. Legs: I: 30.3 (8.5, 3.8, 8.0, 7.8, 2.2); II: 33.1 (9.5, 3.9, 9.0, 8.6, 2.1); III: 23.1 (7.1, 3.2, 5.8, 5.2, 1.8); IV: 25.9 (8.0, 3.0, 6.5, 6.4, 2.0). Spination follows the generic pattern except metatarsus IV: r1-1-2. Epigyne: EF slightly longer than wide; MAB barely conspicupous embedded in EF; MS 1.5 times longer than wide, extending over posterior margins of LL; EP triangular, roughly as long as wide, opening at posterior margin of MS; LL touching posteriorly ( Figs 200 View FIGURES 196–202 , 206 View FIGURES 203–207 ). Vulva: internal ducts with FW dilated, postero mediad; GP 3 times longer than wide, anteriad; SP elongated with few grooves; FD antero laterad ( Figs 200–201 View FIGURES 196–202 , 207 View FIGURES 203–207 ).

Variation. Females (n = 2): total length 15.3–17.8; prosoma length 5.9–7.1; femur I length 7.0–8.5.

Distribution. Known from the Lesser Antilles ( Fig. 315 View FIGURES 315–318 )
