Type material. Holotype: ɞ from Floresta da Cicuta, Volta Redonda [23º31' S; 44º06' W], Rio de Janeiro, Brazil, 11–18 June 2001, Equipe Biota leg. ( IBSP 54023). Paratypes: 3ɞ, 2Ƥ, with the same data as holotype ( IBSP 54013; 54018; 54024; MZSP 31776–31777).
Additional material examined. BRAZIL. Rio de Janeiro: 1ɞ, Jacarepaguá, Serra Carioca [22º55' S; 43º21 W] ( MNRJ 126); 2ɞ, 1Ƥ, Volta Redonda, Floresta da Cicuta [23º31' S; 44º06' W] ( IBSP 54025; 54563).
Etymology. The specific name is a combined noun phrase in apposition taken from the Tupi Indian language and means “small keel” (cupepema = keel; ayri = small) and refers to the small subdistal ventral keel on the embolus of the male palp.
Diagnosis. The males of Caayguara cupepemayri sp. nov. resemble those of C. cupepemassu sp. nov. by the general conformation of the male palp, with simple RTA without ventral lobes and embolus with many keels and projections ( Figs 39 View FIGURES 39 – 43 ; 44, vk, sk). They are distinguished by the ventral keel of the embolus that is much smaller than in C. cupepemassu sp. nov. ( Fig. 44 View FIGURES 44 – 48 ; vk) and by the lack of a distal, ventrally bent keel, covering part of the distal region of the embolus. The females resemble those of C. juati sp. nov., C. apiaba sp. nov., C. ajuba sp. nov. and C. cupepemassu sp. nov. by the general conformation of the epigynum ( Figs 26 View FIGURES 24 – 28 , 31 View FIGURES 29 – 33 , 36 View FIGURES 34 – 38 , 41 View FIGURES 39 – 43 ) but are distinguished from the latter by the chalice-shape of the median septum ( Fig. 46 View FIGURES 44 – 48 ).
Description. Male (IBSP 54023): Dorsal shield of prosoma orange, slightly darker along fovea. Chelicerae, legs and pedipalps orange. Sternum pale yellow with orange margins. Labium orange. Endites pale yellow, distally cream colored. Opisthosoma brownish gray. Dorsally two pairs of white marks on anterior half and few white marks scattered medially on posterior half. Ventrally mottled with white spots laterally. Total length 8.7. Prosoma: 3.7 long, 3.2 wide. Opisthosoma: 4.9 long, 2.4 wide. Eye diameters: 0.24, 0.24, 0.16, 0.24; interdistances: 0.16, 0.04, 0.28, 0.24, 0.18, 0.14. Leg measurements: I: 24.5 (6.5, 2.1, 7.2, 6.5, 2.2); II: 27.6 (7.3, 2.2, 8.0, 7.5, 2.6); III: 18.0 (5.3, 1.7, 5.1, 4.4, 1.5); IV: 20.7 (6.0, 1.7, 5.7, 5.6, 1.7). Spination follows the generic pattern. Palp ( Fig. 77 View FIGURES 71 – 82 ): RTA simple with no ventral lobes; dorsal projection short ( Figs 44–45 View FIGURES 44 – 48 ); tegulum with no projections; embolus with prolateral subdistal keel ( Fig. 44 View FIGURES 44 – 48 ; sk); pars pendula inconspicuous.
Female (IBSP 54013): Coloration pattern as in male. Total length 8.4. Prosoma: 3.8 long, 3.5 wide. Opisthosoma: 4.4 long, 2.3 wide. Eye diameters: 0.22, 0.24, 0.18, 0.24; interdistances: 0.20, 0.06, 0.32, 0.30, 0.22, 0.16. Leg measurements: I: 18.7 (5.1, 2.0, 5.4, 4.6, 1.6); II: 21.0 (6.0, 2.1, 5.8, 5.4, 1.7); III: 4.3, 1.6, 3.8, 3.0, 1.2); IV: 16.3 (4.9, 1.6, 4.2, 4.3, 1.3). Spination follows the generic pattern. Epigynum: epigynal field rounded, slightly longer than wide; touching part of lateral lobes shorter than median septum ( Fig. 46 View FIGURES 44 – 48 ). Vulva: pp showing a narrow proximal and 7–8 linearly arranged lobes ( Fig. 47 View FIGURES 44 – 48 ); fd shorter than half pp showing a narrow proximal and 7–8, longitudinal ( Figs 47–48 View FIGURES 44 – 48 ).
Variation. Males (n = 6): total length 7.9–8.9; prosoma 3.4–3.7; femur I 6.1–6.8. Females (n = 3): total length 8.4–9.2; prosoma 3.3–3.8; femur I 4.5–5.1.
Distribution. Only known from Rio de Janeiro, southeastern Brazil ( Fig. 85 View FIGURE 85 ).
