Other material examined. BRAZIL, Bahia State: 1 ♂ brittle, badly damaged ( MNRJ 18928 ), Ilhéus, Ilha do Barbosa , without further data .

Distribution. Brazil, Bahia State: Camacan, Ilhéus and Una. This species is sympatric with C. pestifer sp. nov. in Ilhéus and with Cajango vindicator sp. nov. in Camacan.

Diagnosis. Body background color in both sexes brown; scutal areas with several granules ( Figs. 3a, c ). Anal operculum with large, rounded apophysis in male, much smaller apophysis in females ( Figs. 3a, c ). Cx IV with retrolateral, apical, spiniform apophysis in both sexes, larger in males ( Figs. 3a, c ). Fe IV of both sexes without dorso-basal apophysis. Basal lobes of VP projected to the sides as triangles ( Fig. 6c ). Flabellum quadrangular, finely serrated ( Fig. 6a ).

Description of male holotype. Measurements: CL = 3.4, CW = 4.2, AL = 4.3, AW = 7.8. Pp = 9.1. Legs, I: Fe = 6.4, Ti = 4.5, Mt = 7.2; II: Fe = 14.9, Ti = 12.0, Mt = 15.3; III: Fe = 11.0, Ti = 6.4, Mt = 11.8; IV: Fe = 14.5, Ti = 11.2, Mt = 20.1.

Dorsum. Large and slender animal, with granulated tegument and elongate legs in predominantly brown hues. DS gamma pyriform, with posterior border slightly concave. Carapace pentagonal, with ocularium at its anterior portion, but set far away from anterior margin of scutum. Ocularium moderately high, armed with two high parallel spines. Frontal hump also moderately elevated, with two small acuminate tubercles. Anterior border of scutum with one tubercle each side. Areas of dorsal scutum all covered with moderate-sized tubercles, each with a larger paramedian pair, growing larger posteriorly, so that the pair in area III is the largest. Mesotergum divided into three areas; area I divided in broadly connected halves. Area V and free tergites each with a transverse row of 6–14 tubercles. Anal operculum with a very large, median, lanceolate apophysis.

Legs. Cx IV much larger than the other coxae taken together, slanted. Stigmatic area with elongate axis, with short branches, sternite II square. Cx IV oblique, visible beyond scutum in dorsal view, with strong, straight and uniramous prolateral apical apophysis and strong retrolateral apical apophysis. 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 proximally (RL1 and RL2, Fig. 5 ), two more in the middle (RL5 and RL6), and one more distally (RL9); other rows formed by minute granules. Tarsal counts 6(3) / 15(4) / 8 / 10.

Color (in 75% ethanol). Background color of dorsal scutum Strong Yellowish Brown (#74), with lighter patches of Moderate Yellow (#87) along the grooves and arborescent in lateral margins of scutum. Mesotergal granules Brilliant Greenish Yellow (#98). Chelicerae and pedipalps Brilliant Greenish Yellow (#98) and densely reticulated in Moderate Olive (#107). Legs I–III up to femora predominantly Light Olive (#106), with lighter granulation. Cx IV background Dark Grayish Red (#20), with apex and rest of podomeres Very Dark Purplish Red (#260). Apical rim of Tr IV Dark Reddish Orange (#38). Ventral Cx and stigmatic area predominantly Strong Greenish Yellow (#99), with dense honeycombed Brownish Gray (#64).

Male genitalia ( Figs. 6a–c ). Basal lobes of VP robust, leaning upon the truncus, projected to the sides as triangles. MS A1 to A3 and B1 all robust, subequal, and set at the rim of basal lobe, forming an arch. D1 set close to E2. Flabellum quadrangular, finely serrated.

Female ( Figs. 3c, d , 4d ). Similar to male in color, proportions, and armature. It differs from male by: (1) armature of Cx IV: weaker prolateral apical apophysis and no retrolateral apical apophysis; (2) Fe IV with only rows of smaller spines; (3) smaller apophysis on anal operculum; and (4) scutal area III with a pair of strong spines instead of low tubercles.
