Figs 63 – 74

Type material. Holotype: male, DOMINICAN REPUBLIC: Barahona: Highway 44 south of Barahona, 18.138° N, 71.070° W, elev. 50 m, 14 July 2009, coll. W. Maddison, G. B. Edwards, J. Zhang, G. Ruiz, WPM#09-031 (UBC-SEM AR00042). Paratypes: 1 female, same data as holotype (UBC-SEM AR00043); 2 males and 5 females in five vials, same data as holotype.

Etymology. Latin adjective brunnea (brown), referring to the brown markings on the male dorsal abdomen.

Diagnosis. Resembles Anasaitis adorabilis in color pattern, but differs by the lack of the ‘U’-shaped marking on the carapace (Figs 69 – 70), the shape of the embolus and the proximal tegular lobe (Fig. 71), and the longer copulatory ducts (Fig. 74).

Description. Male (holotype, UBC-SEM AR00042). Carapace length 1.4 (variation 1.1 – 1.4, n=3); abdomen length 1.3. Chelicera: dark brown. Palp (Figs 71 – 72): light yellow brown to gray brown. Proximal tegular lobe obvious, retrolateral sperm duct loop wide. Embolus short. Retrolateral tibial apophysis finger-like, tibia without ventral bump. Measurements of legs: I 3.4, II 2.2, III 2.5, IV 2.3. Color in alcohol (Fig. 69): carapace dark brown, with a pair of markings extending to posterior end of carapace composed of yellowish scales; abdomen dark brown, with a middle yellow brown stripe and yellow brown posterior end; ventral abdomen light yellow laterally and gray brown in the middle; legs light yellow brown to yellow brown.

Female (paratype, UBC-SEM AR00043). Carapace length 1.3 (variation 1.1 – 1.3, n=6); abdomen length 1.5. Measurements of legs: I 2.1, II 1.8, III 2.4, IV 2.2. Epigynum (Figs 73 – 74): no obvious window or median septum. Copulatory ducts narrow and short, with accessory gland; spermathecae spherical. Color in alcohol (Fig. 70): similar to that of male, but the middle stripe on abdomen less distinct.

Natural history. Specimens were found on leaf litter in a humid forest.
