Type material. Male holotype and female paratype from Morro do Pai Inácio (12°27’27”S; 41°28’23”W), Lençóis, Bahia, Brazil, 23.X.1999, Freddy Bravo leg., deposited in IBSP 166246; 166247 respectively. Paratypes: male from Carmo do Rio Claro, Minas Gerais, Brazil, X.1947, J.C. de Carvalho, deposited in MNRJ 13163 and female from Parque Nacional da Serra do Cipó, Santana do Riacho, Minas Gerais, Brazil, V.1998, A.J. Santos, deposited in MNRJ.

Etymology. The specific name is a patronymic in honor of Freddy Bravo, the collector of the types from Bahia.

Diagnosis. Males of Umuara freddyi resemble those of Umuara fasciata by the shape of the apophysis of embolic process (see Brescovit, 1997, figs. 242–245), but can be recognized by the retrolateral tibial apophysis long and not bifid ( Figs. 2 D, E). Females resemble those of U. junin by the epigynum with large median hood and curved lateral borders (see Brescovit, 1997, figs. 255–256), but can be distinguished by the more elongated median hood and by the lateral borders not curved basally ( Fig. 2 G).

Description. Male (IBSP 166246). Carapace orange with cephalic area and thoracic groove darker; chelicerae dark brown; labium and endites orange; sternum and legs yellow; abdomen dorsally grayish with scattered gray stripes; spinnerets yellowish ( Fig. 1 A). Total length 5.4, carapace length 2.7, width 2.0. Clypeus height 0.1.

Chelicerae 1.3 long, with four promarginal teeth and eight retromarginal denticles. Leg measurements: Leg I—femur 2.4/ patella 0.9/ tibia 2.5/ metatarsus 2.6/ tarsus 0.9/ total 9.3; II—2.9/ 1.0/ 2.1/ 2.1/ 0.8/ 8.9; III—1.5/ 0.8/ 1.5/ 1.6/ 0.6/ 6.0; IV—2.5/ 0.8/ 2.2/ 2.7/ 0.5/ 8.7.

Palp: tibia with wide furrow below retrolateral tibial apophysis; distal tegular projection elongated; median apophysis curved; embolus short ( Figs. 2 A–F).

Female (IBSP 166247). Coloration as in male except abdomen, grayish ( Fig. 1 B). Total length 6.7, carapace length 2.5, width 2.0. Clypeus height 0.1.

Chelicerae 1.20 long, with three promarginal teeth and eight retromarginal denticles. Leg measurements: Leg I—femur 2.2/ patella 0.7/ tibia 2.1/ metatarsus 1.7/ tarsus 0.7/ total 7.4; II—1.7/ 0.6/ 1.8/ 1.5/ 0.8/ 6.4; III—1.7/ 0.6/ 1.3/ 1.2/ 0.5/ 5.3; IV— 2.2/ 0.7/ 2.0/ 2.2/ 0.6/ 7.7. Leg spination: I—tibia v2-2 -0, p0, r0, metatarsus p0; II—tibia v2-2 -0, p0, r0, metatarsus p0, r0; IV—tibia v1 -p-2-2, metatarsus v2-2 -2. Epigynum: copulatory ducts long and curved; seminal receptacles small; fertilization ducts two times the length of spermathecae; spermathecae separated by half their diameter ( Fig. 2 H).

Variation. Males (n=10): total length 5.0–5.9; carapace 2.25–2.8; femur I 1.6–2.6. Females (n=7): total length 4.4–7.1; carapace 1.8–2.5; femur I 1.5–2.1.
