Description of female, color in alcohol. Body dark-colored, pedipalps and endites reddish-brown ( Figures 5–7 View Figures 5–10 ). Cephalothorax longer than wide, with greater height above the PLE and divided by a large furrow covered with white hairs proximal to the PLE; dark brown ocular quadrangle, delineated by a very faint dark band, scattered iridescent scales ( Figure 5 View Figures 5–10 ); sternum octagonal in shape ( Figure 6 View Figures 5–10 ). Chelicerae are light-yellow, vertical, and small, with four large teeth on the retrolateral margin, three small prolateral teeth, three large teeth on the prolateral margin, and a small inconspicuous prolateral medial tooth, with small, curved fang with small denticles on the inner margin, and a small tubercle on the base ( Figure 12 View Figures 11–12 ). The abdomen is globose, with a faint white transverse band proximal to the anterior margin and a dorsal hump scattered with white hairs, and a longitudinal central olive-green ventral band ( Figures 5, 7 View Figures 5–10 ). The first and second pair of legs are light-yellow with a dark brown dorsal band, the metatarsi dark brown, and the apical region of the segment lighter; the third and fourth pair of legs are dark brown, each segment with a light-yellow apical region, except for the metatarsi and tarsi which are light yellow ( Figures 5, 7 View Figures 5–10 ). Epigynum sclerotized, reddish-brown, circular, with a clear gonopore (Go, Figures 13–15 View Figures 13–14 View Figures 15–16 ), connected directly with the copulatory ducts (CD, Figures 14–16 View Figures 13–14 View Figures 15–16 ), which immediately curve, and then continue straight until they fold back on themselves, forming the spermathecae (Sp, Figures 14–16 View Figures 13–14 View Figures 15–16 ) until reaching the end, culminating in the fertilization duct (FD, Figures 14–16 View Figures 13–14 View Figures 15–16 ).

Measurements for three females: TL= 4.1–4.3; CL= 1.72–1.75; CW= 0.95–0.98; AL= 2.12–2.15; AERW= 0.88–0.91; PERW= 0.84–0.87; LOQ= 0.76–0.79; PMEP= 0.41–0.43; eyes of the second row separated from the ALE by 0.15–0.17 mm and from the PLE by 0.17–0.19 mm. Spination: Leg I: F= d 0-0-1p*; P= 0; T= v 0-0-2; M=0-2-2. Leg II: F= d 0-0-1p*; P= 0; T= v 0-0-2; M=v0-2-2. Leg III: F= d 0-0-1p*; P= 0; T= v 0-0-2; M=v0-2-2. Leg IV: F= d 0-0-1p*; P= 0; T= v 0-0-2; M=v2-2-2.

Description of male, color in alcohol. Body dark-colored; pedipalps and endites reddish-brown ( Figures 8– 10 View Figures 5–10 ). Cephalothorax longer than wide ( Figures 2–4 View Figures 1–4 ), divided by a large furrow covered with white hairs proximal to the PLE; dark brown ocular quadrangle, delineated by a very faint dark band, with scattered iridescent scales ( Figures 8–10 View Figures 5–10 ); sternum octagonal in shape ( Figure 9 View Figures 5–10 ). Chelicerae light yellow, vertical, and small, dentition as in the female, fang small and curved with small denticles on the inner margin and a small tubercle at the base ( Figure 11 View Figures 11–12 ). Abdomen with scattered white hairs, with a faint white transverse band proximal to the anterior margin, and a longitudinal central olive-green ventral band ( Figure 10 View Figures 5–10 ). The first pairs of legs are light yellow, except the femur, patella, and tibia light brown, with a dark brown band on each side ( Figure 8, 10 View Figures 5–10 ); the second pair of legs is light yellow, with a dark brown dorsal band, metatarsi and tarsi light yellow ( Figure 8, 10 View Figures 5–10 ); third and fourth pair of legs dark brown, each segment with a light-yellow apical region, except for the tarsi which are light yellow ( Figure 8; 10 View Figures 5–10 ). The pedipalp is small and globose, with a simple bulb ( Figures 17–18 View Figures 17–20 ), embolus short and thin, occupying a fossa on the prolateral side of the bulb ( Figures 21–22 View Figures 21–24 ); the sperm duct (SD) begins in the upper part of the bulb and continues through the retrolateral side and surrounding the bulb ( Figures 19–20 View Figures 17–20 ); the retorlateral tibial apophysis (RTA) is well developed, visible in a ventral view ( Figures 23–24 View Figures 21–24 ).

Measurements for two males: TL= 3.9–4.0; CL= 1.75-1.86; CW= 0.91–1,01; AL= 1.92–2,02; AERW= 0.93– 1,03; PERW= 0.81–0.91; LOQ= 0.55–0.65; PMEP= 0.35–0.37; eyes of the second row separated from the ALE by 0.16–0.18 mm and from the PLE by 0.17–0.19 mm. Spination: Leg I: F= d 0-1p*-0; P= 0; T= v 2-0- 2; M=0-2-2. Leg II: F= d 0-1p*-0; P= 0; T= v 2-0-2; M=v0-2-2. Leg III: F= d 0-0-1p*; P= 0; T= v 0-0-1r; M=v0-2-2. Leg IV: F= d 0-0-1p*; P= 0; T= v 0-0-1r; M=v2-2-2.

Habitat and distribution. Erica eugenia is a myrmecomorph. In the Brazilian Cerrado it was found in the phytophysiographic province of the Cerrado sensu strictu, near nests of ants of the genus Crematogaster Lund 1831 , in low densities ( Figures 25–26 View Figures 25-26 ). Therefore it can be considered a rare species in the Cerrado, which is consistent with previous records. Despite being a common species in some localities, it is usually a rare species ( Rubio et al. 2018). This is the only species described for the genus Erica , with a known distribution that extends from Argentina to southeastern Brazil, Panama (Bugaba, Champion), and Peru ( Figure 27 View Figure 27 ). The present study extends its known distribution to the central region of the Brazilian Cerrado. Some differences that I have observed suggest, however, that the record of this species from Argentina represents a different, undescribed species (G. D. Rubio, unpublished data).
