Etymology. The noun in apposition refers to the type locality.

Diagnosis. Males of T. ebano   n. sp. differ from other species of the genus by the presence of two short patellar apophyses in the male palp (Figs. 5D–F, 6D, F). Females resemble those of T. maricao   n. sp. by the large and suboval atrium in the epigynum but can be distinguished by the sharply curved spermathecae (Fig. 5G, H).

Description. Male (Holotype, IBSP 214254). Carapace and chelicerae orange. Labium and endites yellow. Sternum cream. Legs yellow with sparse gray bands. Abdomen dorsally cream with longitudinal gray band, ventrally white (Fig. 5A). Total length 4.7, carapace length 2.2, width 1.7. Clypeus height 0.08. Eye diameters and interdistances: AME 0.08, ALE 0.12, PME 0.14, PLE 0.14; AME–AME 0.06, AME–ALE 0.06, PME–PME 0.10, PME–PLE 0.10, ALE–PLE 0.06. Chelicerae 1.5 long, with 4 promarginal teeth and 8 retromarginal denticles ( Fig. 6A View FIGURE 6 ). Leg measurements: Leg I—femur 3.1/ patella 1/ tibia 3.6/ metatarsus 3.2/ tarsus 1.55/ total 12.45; II—2.8/ 0.9/ 2.4/ 2.7/ 1/ 9.8; III—1.7/ 0.7/ 1.6/ 1.7/ 0.55/ 6.25; IV—2.7/ 1.1/ 2.4/ 2.7/ 0.8/ 9.7. Leg spination: I-II—tibia v2-2 - 0, p1-1-1, r1-1-1, metatarsus v2-2 -0, p1-1-1, r1-1-1; III—tibia v2-2 -0, p1-1-0, r1-1-0, metatarsus v2-2 -2, p1-1-1, r1-1-1; IV—tibia v2-2 -2, p1-1-0, r1-1-0, metatarsus v2-2 -2, p1-1-1, r1-1-1. Palp: ventral patellar apophysis absent, retrolateral patellar apophysis short and triangular, dorsal patellar apophysis triangular, retrolateral tibial apophysis very short and basal retrolateral apophysis rounded, median apophysis with sharp distal area and narrowed in the base; ventral tegular process short, embolus filiform (Figs. 5C–F, 6B–F). Abdomen: length 2.3, epigastric furrow 0.5 from tracheal spiracle, spiracle 0.8 from base of spinnerets.
