Etymology. The epithet, to be treated as a Latin adjective, refers to the dorsal expansion on the male palpal femur (Fig. 45).

Diagnosis. Males of H. femoratus sp. nov. are similar to those of H. miles Simon and H. terraemediae sp. nov. for the dilated femora (Fig. 45) and reduced RTA (Figs 44, 55). However, H. femoratus sp. nov. can be distinguished from those for having a slender tip of the embolus (Fig. 43). Females of H. femoratus sp. nov. are similar to those of H. terraemediae sp. nov. in having digitiform glands curving from the center of the epigyne to the anterior lateral portions, but can be distinguished for the more perpendicular copulation openings (Fig. 46) (the female of H. miles is unknown). Hypaeus terraemediae sp. nov. also seems to have an extra loop in the copulation duct.

Description. Male (holotype, MPEG 21551). Total length: 7.70. Carapace dark brown with yellow spot behind the fovea bearing white setae (Fig. 39), 3.50 long, 2.60 wide, 2.10 high. Ocular quadrangle 2.00 long. Anterior eye row 2.35 wide, posterior 2.20 wide. Black eyebrow. Sparse white setae between ALE and PLE. AME 0.85 in diameter. Clypeus 0.50 high, of same color, with no setae (Fig. 49). Chelicera dark brown with frontal excavation and dilated dorsal portion, which bears a short mastidion (Fig. 50); four teeth on promargin, three on retromagin. Labium and endite dark browm. Endite with projected lateral. Sternum margins dark brown, center yellow (Fig. 41). Palp: femur ventrally curved, dorsally dilated in distal half; tibia with very short RTA and small retrolateral projections; embolus arising from proximal tegulum, slender at distal half. Legs 1432 (10.50/ 9.15/9.00/7.65). Coxae and trochanters yellow. Femora yellow, dark brown distally, lighter in posterior legs. Patella, tibia and metatarsus I dark brown, lighter in posterior legs, tarsi yellow. Length of femur I 3.30, II 2.45, III 3.15, IV 3.00. Patella + tibia I 4.60, II 3.00, III 3.10, IV 3.05. Metatarsus + tarsus I 2.60, II 2.20, III 2.75, IV 3.10. Abdomen pale with a light brown dorsal pattern (Fig. 39); ventrally with median, longitudinal dark brown stripe (Fig. 41). Spinnerets light brown.

Female (paratype MPEG 21529). Total length: 7.10. Carapace light brown with darker cephalic area and dark brown margins (Fig. 40), 3.20 long, 2.40 wide, 1.70 high. Ocular quadrangle 1.71 long. Anterior eye row 1.66 wide, posterior 1.28 wide. Sparse white setae among eyes. No eyebrow. AME 0.80 in diameter. Clypeus 0.20 high, with dark brown margin (as in H. terraemediae sp. nov., Fig. 58). Chelicera with no mastidion, inner portion yellow, base and laterals dark brown (as in H. terraemediae sp. nov., Fig. 58); four teeth on promargin and three on retromargin. Labium and endite light brown. Sternum yellow. Legs 4312 (7.85/7.60/7.25/6.25). Coxae and trochanters yellow. Femora yellow with darker tips. Patellae and tibiae light brown, darker at joints. Metatarsi and tarsi light brown, lighter in posterior legs. Length of femur I 2.25, II 2.00, III 2.60, IV 2.55. Patella + tibia I 3.00, II 2.50, III 2.65, IV 2.70. Metatarsus + tarsus I 2.00, II 1.75, III 2.35, IV 2.60. Abdomen as in male (Fig. 40). Epigyne with a pair of copulation openings, long digitiform gland ducts and long and stout copulation ducts (Figs 46–48, 62–63). Spinnerets light brown.
