Type material. Holotype: male, DOMINICAN REPUBLIC: La Vega: P. N. Armando Bermúdez, 19.06 – 19.07 ° N, 70.86 – 70.88 ° W, elev. 1120 – 1250 m, 8 – 9 July 2009, coll. W. Maddison, G. B. Edwards, J. Zhang, J. Brocca, WPM#09-018 (UBC-SEM AR00071). Paratypes: 1 female, same data as holotype (UBC-SEM AR00072); 1 male, same data as holotype; 1 female and 1 male, DOMINICAN REPUBLIC: La Vega: near Manabao, 19.076° N, 70.827° W, elev. 980 m, 8 – 10 July 2009, coll. W. Maddison, G. B. Edwards, J. Zhang, J. Brocca, WPM#09-017; 12 females and 8 males, same data as previous.

Etymology. Latin adjective flavus (yellow), referring to the yellow palp of the male.

Diagnosis. Similar to Truncattus cachotensis in shape of the epigynum and palp, but differs in the narrower median septum of the epigynum (Fig. 261), the large secondary spermatheca (Fig. 262) and the long retrolateral tibial apophysis (Fig. 259).

Description. Male (holotype, UBC-SEM AR00071). Carapace length 1.3 (variation 1.1 – 1.4, n=11); abdomen length 1.4. Chelicera (Fig. 260): yellow brown. Palp (Fig. 259): femur, patella and tibia light yellow; cymbium brown. Retrolateral sperm duct loop narrow. Retrolateral tibial apophysis long and thin; ventral tibial bump obvious. First leg with ventral fringes on tibia and patella. Measurements of legs: I 2.5, II 1.9, III 2.1, IV 2.4. Color in alcohol (Fig. 257): carapace dark brown to red brown with narrow lateral marginal stripes composed of white setae, posterior part with white setae medially; abdomen gray brown with light yellow markings in the middle, posterior end dark brown; venter light yellow; first pair of legs dark brown with tarsus light yellow, other legs light yellow to brown.

Female (paratype, UBC-SEM AR00072). Carapace length 1.1 (variation 1.0–1.2, n=14); abdomen length 1.7. Measurements of legs: I 1.7, II 1.6, III 1.7, IV 2.1. Epigynum (Figs 261–262): window small, with opening to copulatory duct at posterior end. Copulatory ducts short, with accessory gland; secondary spermathecae obvious; primary spermathecae oval. Color in alcohol (Fig. 258): similar to that of male, but first pair of legs lighter in color.

Natural history. Specimens were found on tree trunks.
