Types. Holotype: male from Punta Negra, Maisí  , Guantánamo, Cuba (20 ° 5 ' 37.39 "N, 74 ° 14 ' 11.50 "W), under Agave  sp., Aug. 8, 2000, A. Sánchez col., deposited in IBSP 164682. Paratypes: two females with same data as holotype, deposited in IBSP 164683 and IBSP 164684.

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Specimens of L. maisi  sp. nov. resemble those of L. mogote  sp. nov. and L. taino  by the globose palpal tibiae in the male palp, but can be distinguished by the form of embolus ( Figs. 17−18View FIGURES 17 − 24) and by the hand-like receptacles with 5−6 lobes ( Figs. 47−48View FIGURES 45 − 48).

Description. Male (holotype, IBSP 164682): Carapace orange, darker in cephalic region ( Fig. 19View FIGURES 17 − 24). Chelicerae, labium and legs orange ( Fig. 20View FIGURES 17 − 24). Endites yellow at base and orange distally. Sternum yellowish orange. Palp with cymbium and tibia orange and rest yellow. Abdomen gray. Total length 7.5. Carapace 3.3 long, 3.1 wide. Clypeus 1.1 high. Eye diameters: ALE 0.55, PME 0.5, PLE 0.5. Leg measurements: I: femur 8.0/ patella 1.4 / tibia 9.5 / metatarsus 9.6 / tarsus 1.6 / total 30.1; II: 8.9 / 1.3 / 10.6 / 10.7 / 1.6 / 33.1; III: 7.6 / 1.3 / 7.4 / 10.7 / 1.5 / 28.5; IV: 8.0/ 1.3 / 9.4 / 9.7 / 1.6 / 30. Leg formula: 2143. Sternum 1.9 long, 1.7 wide. Palpal tibia 1.0 long, 0.7 wide. Palp with cymbium almost the same length of tegulum and embolus longer than cymbium ( Figs. 31−32View FIGURES 31 − 38).

Female (paratype, IBSP 164683): Coloration as in male, except abdomen darker ( Figs. 19−20View FIGURES 17 − 24). Total length 8.8. Carapace 3.9 long, 3.1 wide. Clypeus 1.1 high. Eye diameters: ALE 0.55, PME 0.55, PLE 0.5. Leg measurements: I: femur 7.0/ patella 1.3 / tibia 7.1 / metatarsus 7.3 / tarsus 1.2 / total 23.9; II: 7.2 / 1.4 / 7.5 / 7.8 / 1.2 / 25.1; III: 6.2 / 1.4 / 5.2 / 6.7 / 1.1 / 20.6; IV: 6.7 / 1.3 / 5.8 / 7.7 / 1.3 / 22.8. Leg formula: 2143. Sternum 1.8 long, 1.7 wide. Palpal tibia 0.9 long, 0.25 wide. Palpal tarsus 1.1 long, slender at tip ( Figs 21−22View FIGURES 17 − 24). Epigynum as in figs. 47−48.

Variation. Female (n= 4): total length 7.5 −9.0, carapace 3.0− 3.9 long, femur I 6.1 −7.0 long. Palpal tibia 0.75−0.9 long, 0.2−0.25 wide. Palpal tarsus 0.9−1.1 long.
