Diagnosis. Males of Masteria aimeae  resemble those of M. golovatchi  in having a group of megaspines on tibia I, but differ in the elongated palpal bulb and embolus ( Fig. 20BView FIGURE 20). Females resemble those of those of M. golovatchi  in the spermathecae having a dense basal glandular region and projected base of spermathecae but differ in the unequal size of the lobes, with a less projected base ( Fig. 20DView FIGURE 20).

Description. Male (Holotype). Color: carapace in dorsal view yellowish, carapace in ventral view, legs and abdomen whitish. Body measurements, see Alayón, 1995, p. 2–5. Eyes: six, posterior row slightly recurved. AME absent, ALE 0.05, PME 0.05, PLE 0.06. Basal segment of chelicerae with nine prolateral teeth, and 4–5 smaller mesobasal teeth. Spination: see Alayón, 1995: 2-5. Tibia I with four to six strong prolatero-apical spines and metatarsus with six to eight prolatero strong spines ( Fig. 20CView FIGURE 20). Palpal tibia 2.5 times length of cymbium, with row of dorsal and ventral elongated slender setae. Cymbium as long as wide with five apical spines and two on prolateral lobe. Palpal bulb with curved embolus, largest than length of tegulum ( Fig. 20A –BView FIGURE 20). PLS: basal, medial and apical, 0.35, 0.40, 0.38 long.

Female ( IBSP 167156). Color: carapace in dorsal view yellowish, carapace in ventral view, legs and abdomen whitish. Total length 3.60. Carapace 1.66 long, 1.29 de largura. Abdomen 1.94 long. Fovea 0.13. Clypeus 0.03. Ocular tubercle 0.16 long, 0.22 wide. Eyes: six, posterior row slightly recurved. AME absent, ALE 0.08, PME 0.05, PLE 0.08. Basal segment of chelicerae with 10 prolateral teeth, and 10 smaller mesobasal teeth. Labium 0.19 long, 0.32 wide. Sternum 0.72 wide, 0.85 long. Palp: femur 0.94/ patella 0.60/ tibia 0.79/ tarsus 0.25/ total 2.58; Legs I: femur 1.41/ patella 0.85/ tibia 1.19/ metatarsus 0.91/ tarsus 0.38/ total 4.74; II: 1.07/ 0.66/ 0.79/ 0.79/ 0.60/ 3.91; III: 1.16/ 0.60/ 0.75/ 0.88/ 0.66/ 4.05; IV: 1.57/ 0.75/ 1.25/ 1.29/ 0.82/ 5.68; Leg formula 4132. Spination: palp: patella p1, tibia v1-3 ap, p1, tarsus v1-1; Legs I: femur p1, patella v1-2 ap, p1, tibia v1-1 -3ap, p1-1, metatarsus v1-1 -3ap; II: patella v1-1, p1-1, tibia v1-1 -3ap, p1-1, metatarsus v1-1 -1, p1; III: femur p1, patella v2 ap, p1-1, r1, tibia d1-1, v1-1 -3ap, p1-1, r1-1-1, metatarsus d1-1-1, v3-2 -3ap, p1-1-1, r1-1; IV: femur r1-1, patella v1, p1-1, r1-1, tibia d1-1-1, v1-1 -2-3ap, p1-1, r2-1-1, metatarsus d1-2, v3-3 -3ap, p1-1-1, r1-1.
