Etymology: The species name is a noun in apposition and refers to the bird from Greek mythology that rose from its ashes, symbolizing hope. The name alludes to material examined, found after the fire on the collection of Instituto Butantan in May 15, 2010.
Diagnosis: Males of Exocora phoenix n. sp. are distinguished from those of other species in the genus, except from E. proba, by the shape of the lamella characteristica, more rectangular in the proximal part, sinuous and pointed distally, and the shape of the embolic membrane, curved towards the dorsal part, with the proximal part wider and distal part pointed (Figs 1 A–C; 3A, B). Males are distinguished from E. proba by the distal part of the lamella characteristica, bifid in E. proba (Millidge 1991: figs 190, 191). The females are distinguished by the small median projection in the posterior margin of ventral plate of the epigynum; by having the dorsal plate wider in the posterior region, dividing the atrium medially (Figs 1 D; 15A), and by the shape of the copulatory ducts, much longer and sinuous than in the other species (Figs 1 E; 16A).
Description: Male (Holotype IBSP 131228): Total length 2.34. Carapace 1.08 long, 0.9 wide. Orange, with two dorsolateral dark marking. Sternum 0.52 long, 0.62 wide, orange, with dark margins. Clypeus 0.18 high. Chelicerae promargin with two teeth, retromargin with four teeth. Abdomen pale brown, with dark marking and white spots along its surface (Figs 2 A, B). Eyes diameters and interdistances: AME 0.07, ALE 0.11, PME 0.1, PLE 0.11, AME-AME 0.02, PME-PME 0.03, AME-ALE 0.01, PME-PLE 0.04. Eyes, projected anteriorly. Ocular area with bristles (Fig. 2 B). Coxa IV separation 1.22 times their width. Femur I/II/III/IV 1.08/1.0/0.72/ 0.9; patella I 0.36; tibia I 1.1; metatarsus I 1.12; tarsus I 0.62. Legs yellowish, with dark markings on each articles. Tibia I with a thick prolateral macroseta (Fig. 2 C). TmI 0.21. Palpal tibia without apophysis. Protegulum present. Embolic division with small radix. Embolus long and filiform, with posterior origin on the embolic division, curves to ectal side and runs anteriorly, getting into the lamella characteristica, slightly twisted (Figs 1 A–C; 3A, B).
Female (Paratype IBSP 131231): Total length 2.04. Carapace 0.84 long, 0.64 wide. Sternum 0.44 long, 0.5 wide. Clypeus 0.12 high. Chelicerae promargin with 3 teeth, retromargin with 5 teeth. Color pattern same as male (Figs 2 D, E). Eyes diameter and interdistances: AME 0.07, ALE 0.1, PME 0.09, PLE 0.08, AME-AME 0.01, PME-PME 0.02, AME-ALE 0.02, PME-PLE 0.02. Eyes as in male, with fewer bristles in ocular area (Fig. 2 E). Coxa IV separation 1.14 times their width. Femur I/II/III/IV 0.84/0.78/0.6/0.8; patella I 0.26; tibia I 0.76; metatarsus I 0.74; tarsus I 0.52. Legs as in male. Tibia I prolateral macroseta thinner (Fig. 2 F). TmI 0.19. Epigynum prominent, with median projection on the posterior margin of ventral plate. Spermathecae rounded. Fertilization ducts originating in the dorsal part of the spermathecae and oriented mesally (Figs 1 D, E; 15A; 16A).
Variation: Males (n=10): Total length 1.84–2.12; carapace length 0.84–1.04; carapace width 0.66–0.86; femur I length 0.84–1.06. Females (n=10): Total length 1.84–2.3; carapace length 0.78–0.94; carapace width 0.64–0.74; femur I length 0.74–0.92.
