Etymology. The specific name is a combined noun phrase in apposition taken from the Tupi Indian language and means “large keel” (cupepema = keel; assu = large) and refers to the very large subdistal ventral keel on the embolus of the male palp.

Diagnosis. The males of Caayguara cupepemassu  sp. nov. resemble those of C. cupepemayri  sp. nov. by the general conformation of the male palp, with simple RTA without ventral lobes and embolus with many keels and projections ( Figs 39View FIGURES 39 – 43, 44View FIGURES 44 – 48). They can be distinguished from the latter by the very long and wide ventral keel and distal, ventrally bent keel, covering part of the distal region of the embolus ( Fig. 39View FIGURES 39 – 43; vk, dk). The females resemble those of C. juati  sp. nov., C. apiaba  sp. nov. and C. ajuba  sp. nov. by the general conformation of the epigynum ( Figs 26View FIGURES 24 – 28, 31View FIGURES 29 – 33, 36View FIGURES 34 – 38, 41View FIGURES 39 – 43). They are distinguished from the latter by the touching part of lateral lobes being shorter than half the large rounded median septum in the epigynum ( Fig. 41View FIGURES 39 – 43) and by the vulva with pp showing an narrow proximal part, almost as long as the multilobed part, and by the very short fertilization ducts ( Fig. 42View FIGURES 39 – 43).

Description. Male ( IBSP 54056): Dorsal shield of prosoma orange with brown fovea. Chelicerae, legs and pedipalps orange. Sternum cream colored with pale orange margins. Labium and endites pale orange, distally lighter. Opisthosoma dorsally brownish gray, mottled with brown spots and with pair of anterior white marks. Ventrally cream colored. Total length 8.1. Prosoma: 3.3 long, 3.3 wide. Opisthosoma: 4.7 long, 2.6 wide. Leg measurements: I: 22.9 (6.0, 2.1, 6.7, 6.0, 2.1); II: 25.4 (6.7, 2.1, 7.5, 6.7, 2.4); III: 16.8 (4.8, 1.7, 4.7, 4.2, 1.4); IV: 19.2 (5.5, 1.6, 5.2, 5.2, 1.7). Spination follows the generic pattern. Palp ( Fig. 76View FIGURES 71 – 82): RTA simple with no ventral lobes ( Fig. 40View FIGURES 39 – 43); dorsal projection small, slightly triangular (Figs 3940; dp). Tegulum with small triangular projection ( Fig. 39View FIGURES 39 – 43; tp). Embolus with inconspicuous pars pendula.

Female ( IBSP 54054): Coloration pattern as in male. Total length 11.2. Prosoma: 3.9 long, 3.6 wide. Opisthosoma: 7.0 long, 2.6 wide. Eye diameters: 0.22, 0.22, 0.16, 0.24; interdistances: 0.20, 0.06, 0.34, 0.30, 0.20, 0.14. Leg measurements: I: 19.0 (5.1, 2.2, 5.3, 4.8, 1.6); II: 21.4 (5.9, 2.3, 6.1, 5.4, 1.7); III: 14.4 (4.4, 1.7, 3.8, 3.4, 1.1); IV: 16.4 (5.0, 1.7, 4.2, 4.0, 1.5). Spination follows the generic pattern. Epigynum with large rounded median septum ( Fig. 41View FIGURES 39 – 43), epigynal field rounded, slightly wider than long ( Fig. 41View FIGURES 39 – 43). Vulva: pp long and slender with 8–9 linearly arranged lobes on posterior half ( Fig. 42View FIGURES 39 – 43).

Variation. Males (n = 10): total length 7.3–8.7; prosoma 3.1–3.8; femur I 5.8–6.3. Females (n = 10): total length 8.4–12.8; prosoma 3.2 –4.0; femur I 4.1–5.4.

Distribution. Southeastern and southern Atlantic Forest, from central eastern Minas Gerais to northern Rio Grande do Sul ( Fig. 85View FIGURE 85).
