Etymology. The specific name is a noun in apposition that refers to an expression used by people in the Brazilian State of Minas Gerais meaning “large eyes”. The name was used in reference to the size of the eyes in Matta zuiuda  relative to other species in the Quadrilátero Ferrífero Iron Region.

Diagnosis. Matta zuiuda  is separated from most other Matta  species by having two large eyes and ventral cheliceral projections (see Lehtinen, 1981, figs 297, 300; Brescovit, 2005, figs 1, 4). Matta zuiuda  is further separated from M. hambletoni  and M. angelomachadoi  by the less elongate posterior region of carapace ( Fig. 2BView FIGURE 2, compare with Lehtinen, 1981, fig. 297) and by females with a seminal receptacle bearing a slender distal area ( Fig. 1FView FIGURE 1, see Lehtinen, 1981, fig. 310; Brescovit, 2005, fig. 21).

Description. Male (Holotype, IBSP 186527). Cephalothorax and abdomen red-brown. Legs orange with yellow patellae ( Fig. 1AView FIGURE 1). Total length 1.34. Carapace projected, 5.3 long, 0.47 wide, with rugose surface ( Figs 2AView FIGURE 2 ̄B). Sternal surface reticulate. Clypeus oblique, long, five times the diameter of the eyes ( Fig. 2BView FIGURE 2). Eye diameters and interdistances: AME 0.04, AME-AME 0.08; with smooth subocular furrow ( Fig. 2CView FIGURE 2).

Abdomen ovoid with a large sclerotized plate covering the dorsal surface ( Fig. 1DView FIGURE 1); ventrally covered by four sclerotized plates ( Fig. 1AView FIGURE 1). Abdominal plates: a large pulmonary plate with rounded anterior margin, surrounding pedicel and oval book-lung plates, followed posteriorly by a narrow postgenital plate, largest preanal plate, and conical anal plate surrounding spinnerets; laterally with four pairs of narrow plates, most ventral pair shorter than others ( Fig. 4DView FIGURE 4), and a line of four epiandrous spigots ( Fig. 4EView FIGURE 4). Male palp: femur with four long setae and bearing median short and projected plates ( Fig. 4CView FIGURE 4); tibia strongly swollen, rounded posteriorly; cymbium small; bulb pear-shaped, with conductor with elevated border, involving; the base of the long and sinuous embolus, enlarged at the apex, with an acute, laminar projection ( Figs 1BView FIGURE 1 ̄C, 3ĀF).

Vulvae externally with V-shaped receptacle ( Fig. 1EView FIGURE 1); narrow post genital plate and thin copulatory opening ( Fig. 5GView FIGURE 5). Internally with enlarged receptaculum and narrow copulatory ducts; central process straight, elongate and with a globose dorsal fold of the uterus externus ( Fig. 1FView FIGURE 1).

Natural history. Matta zuiuda  is known from caves in the carbonate and ferruginous formations. While all specimens have been collected in caves thus far, we hypothesize that they also occur in the hypogeous edaphic environment.

Distribution. Caves in the State of Minas Gerais, Brazil ( Fig. 30AView FIGURE 30).
