Etymology. This species is named after the spider taxonomist and collector of the type series, Antonio D. Brescovit, in recognition of the importance of his contributions to South American spider systematics.

Diagnosis. ♂♂ differ from other Synotaxus  species by the thin and pointed paracymbium and the patellar apophysis emerging from the base of a conical patellar projection ( Figs. 1View FIGURE 1, 3– 4View FIGURES 3 – 6). ♀♀ resemble S. monoceros (Caporiacco)  and S. bonaldoi  by the presence of a sclerotized internal armature in the epigynum ( Exline & Levi 1965: fig. 28, Fig. 14View FIGURES 11 – 14), which is heart­shaped in S. brescoviti  . ( Figs. 5–6View FIGURES 3 – 6).

Description. ♂ (holotype). Carapace, chelicerae, labium, endites, palps and legs orange, abdomen cream colored. Ocular area overhanging clypeus, with two central curved setae. Legs thin, with numerous setae. Abdomen elongated, pointed posteriorly. Total length 2.5, carapace 1.0 long, 0.9 wide. Patella­tibia I length 4.35, II 2.7, III 1.1, IV 2.2. Abdomen 1.5 long, 0.4 wide. Paracymbium with a basal, prolateral bump and a long, curved retrolateral prong ( Fig. 3View FIGURES 3 – 6). TTA with a long, apical projection ( Figs. 3–4View FIGURES 3 – 6).

♀ (paratype). Body uniformly cream colored. Abdomen shape as in ♂. Total length 5.2, carapace 1.1 long, 0.9 wide. Patella­tibia I length 4.0, II 2.5, III 1.1, IV 2.2. Abdomen 4.1 long, 1.3 wide. Copulatory openings conspicuously delimited laterally ( Fig. 5View FIGURES 3 – 6). Copulatory ducts inconspicuous, apparently absent. Fertilization ducts long and slender, accessory sacs small and posteriorly connected to spermathecae ( Fig. 6View FIGURES 3 – 6).

Variation. ♂♂ from state of Acre (Brazil) have only one larger curved setae on the ocular area, a relatively wider paracymbium and a thinner patellar apophysis. These are tenuous quantitative differences, and the shape and relative size of palpal sclerites are the same from specimens from other localities. Based on this, we consider these specimens as conspecific.

Distribution. Northern and northeastern Brazil ( Fig. 19View FIGURE 19).
