“CAE-01 sp. C”— Kury et al. 2022: 81, fig. 7.
Etymology. Species name is the Latin noun vindĭcātor, ōris (avenger) used in apposition, and it refers to the revenge of the character Cajango in the novel Corpo Vivo, in allusion to the generic name.
Type series. BRAZIL, Bahia State: ♂ holotype, 2 ♀ paratypes (MNRJ 9053), Camacan, Highway BR 101, 28.iii.2012, V. Dill leg; 1 ♂ paratype (MZSP 73451), Uruçuca, Parque Estadual Serra do Conduru (14°29’02.8”S 39°06’10.4”W), 27.viii.2014, S. Outeda-Jorge leg.
Diagnosis. Body background color yellow in both sexes, with carapace and area III more strongly shaded in brown; scutal areas only with a pair of paramedian granules each, and a few scattered extra granules (Figs. 10a, c). Anal operculum with a large lanceolate apophysis, stouter in male (Figs 10b, d). Sternite II narrow and rounded. Cx IV of male without retrolateral apical apophysis (Fig. 10b). Fe IV without dorso-basal apophysis (Fig. 12). Basal lobes of VP not projected to the sides (Fig. 13c). Flabellum quadrangular, finely serrated (Fig. 13a).
Description of male holotype. Measurements: CL = 4.2, CW = 5.0, AL = 5.6, AW = 10.7. Pp = 9.7. Legs, I: Fe = 7.0, Ti = 4.3, Mt = 7.4; II: Fe = 15.8, Ti = 11.8, Mt = 15.8; III: Fe = 11.7, Ti = 6.4, Mt = 10.4; IV: Fe = 16.6, Ti = 10.5, Mt = 18.7.
Dorsum. Large and slender animal, with smooth body and elongate legs in predominant yellow hues. DS gamma pyriform, with posterior border slightly concave. Carapace cordiform, with ocularium at its anterior portion, but set far away from anterior margin of scutum. Ocularium only moderately high, armed with two slightly divergent spines. Frontal hump also moderately elevated, with two small acuminate tubercles. Anterior border of scutum with one tubercle each side. Dorsal scutum glossy, except for one row of scattered tubercles on each lateral area and one transverse row on each area I and II, each row with a highlighted paramedian pair. Mesotergum divided into three areas; area I divided into broadly connected halves. Area III with a paramedian pair of blunt tubercles and a few scattered granules.Area V and free tergites each with a transverse row of 4–12 granules.Anal operculum with a very large, median, lanceolate apophysis.
Legs. Cx IV much larger than the others taken together, slanted. Stigmatic area with elongate axis, with short branches, sternite II narrow and rounded. Cx IV oblique, visible beyond scutum in dorsal view, with strong and straight prolateral apical apophysis, provided with a small secondary branch. Retrolateral apical apophysis lacking. Tr IV with two retroapical apophyses forming a V. Fe IV with PV and RV rows of small tubercles increasing in size apically, RL surface with two stouter spines in the middle (RL4 and RL6) and two more distally (RL7 and RL9), other rows formed by minute granules. Tarsal counts 6(3)/14(4)/8/10.
Color (in 75% ethanol). Dorsal scutum, chelicerae and pedipalps and Tr I–III background Light Yellow (#86). Scutum with Brownish Gray (#64) patches covering most of carapace (including ocularium), anterior border of scutum and region around main armature of area III. Chelicerae and pedipalpi with sparse Brownish Gray (#64) reticulation. Tr I–III heavily mottled in Deep Brown (#56). Legs I–III predominantly Brownish Gray (#64). Leg IV background Deep Brown (56) in some regions getting darker to Brownish Black (#65). Anal operculum Brownish Black (#65). Ventral Cx and stigmatic area predominantly Moderate Greenish Yellow (#102) to Moderate Yellow (#87) with honeycombed reticulation in Moderate Olive Brown (#95). Reticulation much denser on sternites.
Male genitalia (Figs. 13a, b, c). Basal lobes of VP leaning upon the truncus, but mediocre, not projected to the sides. MS A1 to A3 and B1 all robust, subequal and arranged into two groups: A1 and B1 more distal than A2 and A3. Solea of glans somewhat projected apically. Flabellum attenuate quadrangular, finely serrated.
Female (Figs. 10c, d, 11d). Very similar to male in habitus and colors, except for: (1) paramedian armature of area III represented by high capitate spines instead of squat blunt tubercles; (2) tubercles on row at lateral areas higher; (3) Cx IV much smaller, mostly hidden under scutum in dorsal view and without strong dorso-apical apophysis; (4) armature of Tr IV much weaker; (5) dorsal scutum outline gamma classical; (6) Fe IV not curved to the median line and without larger individual spines, although still armed with rows of substantial spines.
