Etymology. The specific epithet is a patronym in honor of Dr. Antonio Domingos Brescovit, by his many contributions to taxonomic and systematic studies on spider of the world.

Diagnosis. Males of Cariamatta brescoviti  sp. nov., resemble those of C. cambridgei (Bryant)  and C. sbordonii (Brignoli)  by their having a long conductor (see Shear, 1978:16–19, figs 25–36; Lehtinen, 1981:69–71, 150, fig. 315a, b) but they can be distinguished from those of all previously mentioned species by a deep furrow in the embolus and conductor base ( Fig. 2DView FIGURE 2), long and straight embolus without apical modifications, and long and knifeshape conductor without basal modifications ( Figs 2BView FIGURE 2, 3BView FIGURE 3). Females can be diagnosed by the epigynum with large seminal receptacles, transversal vulval ducts longer that in C. cambridgei (Bryant)  , C. sbordonii (Brignoli)  and C. blandini Lehtinen  (see Shear, 1978:16–19, figs 32; Lehtinen, 1981:69–71, 150, figs 36, 310; Fig. 3CView FIGURE 3).

Carapace ( Fig. 1View FIGURE 1 D–F): cephalothorax finely reticulated slightly raised and subtriangular-shaped; eyes white, ALE>PLE in size; clypeus high; thoracic region smooth and with radial grooves; Chelicerae with a wide and few develop apophysis on proximal side; endites subquadrangular-shaped with the wide basal edge, narrowing towards the distal edge; labium trapezoidal-shaped and wider that long; sternum rugose with few setae on lateral edges. Legs cuticle striated. Opisthosoma ( Figs 1View FIGURE 1 D–F, 4B): covered with white and black fine setae, mainly on posterior edge; dorsal scutum oval-shaped and smooth; ventral scutum (pulmonar scutum) finely reticulated; lateral scutum long, extending to half of the anal plate; postgenital scutum subrectangular-shaped, long and narrow; preanal scutum rectangular-shaped and wide, with rounded borders. Epigynum ( Figs 3CView FIGURE 3, 4BView FIGURE 4): orifice small and situated on posterior edge of epigynal fold; inner epigynal plate wider than long, seminal receptacles membranous and bean-shaped; vulval ducts long ( Figs 3View FIGURE 3 C–D).

Variation. Males (n=2): total length: 1.00–1.05; carapace length: 0.45–0.50. Females (n=2): total length: 1.12– 1.23; carapace length: 0.43–0.50.

Habitat. The specimens were caught sifting leaf litter, in a semi-humid transitional dry forest (according the tropical dry forest (Bosque Seco Tropical) classes proposed by Etter et al. (2008)), in a fragment of secondary forest, of the Bolivar and Sucre departments. Bolivar presenting an average of temperature 28°C, and an average yearly precipitation close to 1450 millimetres; and Sucre presenting an altitudinal known range of 390 m, with an average yearly precipitation close to 1297 millimetres, 28°C in average of temperature (Rangel-Ch. & Cavajal-Cogollo, 2012), and relative humidity average 83,5%.

Distribution. Only known from its type locality (Bolivar and Sucre departments) ( Fig. 6View FIGURE 6).
