Males of Thaloe maricao n. sp. resembles T. leboulet n. sp. and T. tricuspis (see Brescovit, 1993 , fig. 7) by the palpal patella having three distal projections, but differ by the bifid retrolateral patellar apophysis and by the hook shape median apophysis in the male palp ( Figs. 1 C–F, 2C–F). Females are readily recognizable by the narrow epigynal borders, short and dentate at tip, and very long spermathecae ( Figs 1G, H ). Description. Male ( Holotype , AMNH). Carapace orange with black border eyes. Chelicerae, labium, endites and sternum orange. Legs orange with metatarsus and tarsus yellowish. Abdomen yellow dorsally and cream ventrally ( Fig. 1A ). Total length 4.5, carapace length 2.1, width 1.8. Clypeus height 0.1. Eye diameters and interdistances: AME 0.08, ALE 0.10, PME 0.12, PLE 0.12; AME–AME 0.08, AME–ALE 0.06, PME–PME 0.12, PME–PLE 0.10, ALE–PLE 0.06. Chelicerae 0.9 long, with 4 promarginal teeth and 6-7 retromarginal denticles ( Fig. 2A ).

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, r-1-1-1; IV—tibia v2-2 -1p, p1-1-0, r1-1-0; metatarsus v2-2 -2, p1-1-1, r1-1-1. Palp: ventral patellar apophysis elongate, retrolateral patellar apophysis bifid and dorsal patellar short, retrolateral tibial apophysis short and rounded, basal retrolateral tibial apophysis finger shape, ventral tegular process inconspicuous, embolus filiform ( Figs. 1 C–F; 2C–F). Abdomen: length 2.5, epigastric furrow 0.5 from tracheal spiracle, spiracle 1 from base of spinnerets. Female ( Paratype , AMNH). Coloration as in male, except dorsum of carapace and dorsum of abdomen darker ( Fig. 1B ). Total length 4.6, carapace length 2.1, width 1.6. Clypeus height 0.08.

Abdomen: length 2.5, epigastric furrow 0.8 from tracheal spiracle, spiracle 2 from base of spinnerets. Epigynum: narrow copulatory ducts; spermathecae large anteriorly and narrow and curved posteriorly; globular seminal receptacles, and elongated fertilization ducts ( Figs 1G, H ). Variation. Males (n = 10): total length 4.1–6; carapace 1.7–2.5; femur I 2.4–3.3. Females (n = 10): total length 4.5–5.5; carapace 1.8–2.3; femur I 1.9–2.6. Distribution. Known to Puerto Rico and Virgen Islands (Fig. 7).
