( Figs. 15, 45C,D, 51)
Type material: BRAZIL. Santa Catarina: Itajaí, R. Pinto-da-Rocha, A.B. Kury & A. Giupponi leg., 9.iii.1999, ma holotype, 1 ma & 1 fe paratypes & 2 im ( MNRJ 4488 View Materials ) ; idem, 2 ma & 4 fe paratypes ( MNRJ 4489 View Materials ) ; idem, 1 ma & 1 fe paratypes ( MZSP 28666 View Materials ) .
Diagnosis: E. garibaldiae resembles E. caparaoensis + and E. manero +, which have a conical, short, blunt prolateral basal apophysis on the male trochanter IV, and can be distinguished by: The presence of PAM; ocularium high, with similar-sized tubercles; median spine of scutal area III of medium size, not surpassing groove V; trochanter IV with short prolateral apical apophysis dorsally inserted; femur IV with 2 ventro-apical spines and without rows of high, pointed tubercles.
Etymology: The name honors an important revolutionary, Anita Garibaldi, who was born in the same state where this species was collected.
Description: Male (holotype): Dorsum ( Fig. 15A,B): Measurements: SL 4.20; SMW 3.80; femur I 1.90; II 3.70; III 2.80; IV 3.50. Median paracheliceral projection smaller than PAM. Ocularium far from anterior scutal margin; high, with 15 tubercles. Carapace with 23 scattered tubercles. Scutal area I with 14–20 scattered tubercles on each side; II with 46; III with 40 and a median spine of medium size, not surpassing groove V; IV with 29 tubercles. Posterior margin of dorsal scutum and free tergites I–III with a row of 12, 15, 16, 16 tubercles, respectively. Anal operculum with 31 tubercles.
Venter: Coxa I with 13–19 tubercles, median and distal ones largest; II with 34–35, distal ones largest; III– IV irregularly tuberculate.
Chelicera: Segment I with 3 tubercles.
Pedipalpus: Trochanter dorsally inflated, with 6–7 tubercles. Femur dorsally with 3 aligned tubercles; ventrally with 1 large basal tubercle, 2 small scattered ones. Tibial setation: Prolateral IiIi, retrolateral IiiIii/ IiIi. Tarsal setation: Prolateral IIi, retrolateral IiIi.
Legs ( Fig. 15C–I): Coxa IV densely tuberculate, with 1 oblique prolateral apical apophysis, this conical, long, blunt, curved posteriad and ventrad, swollen ventro-basally and slightly subapically. Trochanters I–IV with scattered tubercles; IV prolaterally with 1 basal apophysis, this conical, short, blunt, swollen in the middle; 1 conical, short apical apophysis dorsally inserted; retrolaterally with 1 large blunt median tubercle. Femur I with small PDS, RDS, ventrally with 2 rows of slightly enlarged tubercles; II–III with small PDS, medium RDS; II ventrally with 2 rows of tubercles slightly increasing in size distally; III sinuous, ventrally with 2 rows of tubercles increasing in size distally, 1 large pointed prolateral apical tubercle; IV sinuous, with medium PDS, RDS, prolateral one smaller; ventrally with 2 rows of tubercles, prolateral ones increasing in size distally, 2 apical spines. Tibia III ventrally with 2 rows of tubercles increasing in size subapically, retrolateral ones becoming high, pointed; IV with 2 ventro-apical spines, prolateral one larger. Metatarsus I with 1 retroventral apical seta. Tarsal segmentation: 6, 7, 6, 6.
Penis ( Fig. 45C,D): Stylus smooth, apex slightly swollen; without medio-ventral trichomes and angular medio-ventral projection. Ventral process of glans curved; apex blunt, thin. Ventral plate with concave sides; with 3 pairs of curved distal setae; 2 ventral pairs of distal tubercles; 1 pair of short, straight median setae; 4 pairs of straight basal setae.
Coloration: Brown; dark brown on legs. Light brown on tarsi.
Female (paratype; MNRJ 4488): Dorsum: Measurements: SL 4.00; SMW 3.40; femur I 1.70; II 3.20; III 2.40; IV 3.00. Posterior margin of dorsal scutum and free tergites II–III with rows of 10 and 22, 8 and 19, 7 and 15 tubercles, respectively; I with an irregular row of 25 tubercles. Pedipalpus: Tibial setation: Prolateral and retrolateral IiIi. Legs: Coxa II with 1 tubercle on prolateral margin, 3 on retrolateral; IV densely tuberculate, with 1 oblique prolateral apical apophysis, this conical, short, pointed. Trochanter IV with scattered tubercles, with 1 large retrolateral apical tubercle. Femur II with rows of similar-sized tubercles; III ventrally with 2 rows of tubercles slightly increasing in size distally, 2 large apical tubercles; IV ventrally with 2 rows of tubercles slightly increasing in size distally, 1 short prolateral apical spine, 1 large retrolateral apical tubercle. Tibia III ventrally with 2 rows of tubercles slightly increasing in size subapically. Metatarsus I with 2 ventro-apical setae. Tarsal segmentation: 6, 7, 6, 6.
