Etymology. An adjective from the Greek ( brimodes = stern or indignant), due to the thick eyebrow, and their habit of holding the legs tight against the body, as if a person frowning and with arms crossed.

Diagnosis. Male differs from that of M. intentus by having a shorter embolus (Fig. 28; compare to Fig. 6). Female is the only one known in the genus (Figs 33–34).

Description. Male (holotype). Total length: 3.60. Carapace 2.30 long, 1.65 wide, 1.35 high, dark brown, with dense black eyebrow and a pair of lines of white scales around cephalic region (Figs 10–11, 14, 16). Ocular quadrangle 1.20 long. Anterior eye row 1.60 wide, posterior 1.40 wide. Clypeus 0.20 high, with dense, narrow stripe of white setae along border (Figs 12, 14). AME 0.50 in diameter. Chelicera dark brown, small, vertical, with a small mastidion on the face, near the fang articulation (Figs 14, 16); slightly excavated between mastidion and teeth; five separate small teeth on promargin and six teeth on a common base on retromargin; fang with a retrolateral flap form- ing a spoon-like structure (Fig. 15). Palp light brown, with curved femur bearing five dorsal spines, long patella and short embolus (Figs 18, 28–29). Endite light brown, tip curved outwards, with a ventral distal protuberance (Figs 30–31). Labium and sternum dark brown, sternum convex. Legs 1324 (Figs 19–22). Total length of leg I: 4.95 (1.55 + 2.20 + 1.20); II: 3.80 (1.25 + 1.50 + 1.05); III: 4.35 (1.65 + 1.60 + 1.10); IV: 3.50 (1.15 + 1.20 + 1.15). Leg I–II dark brown, fading towards the yellow tarsi; III–IV with dark brown femora, but proximally clear; remaining articles yellow, stained of dark brown on joints. Abdomen dark brown, with poorly defined, narrow stripe of white setae on the anterior border; dorsally with lighter chevrons on posterior half (Figs 10–11, 16); ventrally dark, with four longitudinal light lines. Spinnerets light brown.

Female (paratype). Total length: 3.40. Carapace 1.87 long, 1.37 wide, 1.00 high. Color pattern as in male (Fig. 13). No eyebrow. Ocular quadrangle 1.00 long. Anterior eye row 1.35 wide, posterior 1.25 wide. Clypeus 0.10 high, with no modified setae (Fig. 17). AME 0.45 in diameter. Chelicera with five separate small teeth on promargin and four teeth on a common base on retromargin. Palp short (Fig. 23). Legs 3142 (Figs 24–27). Total length of leg I: 3.05 (0.95 + 1.25 + 0.85); II: 2.64 (0.88 + 1.00 + 0.76); III: 3.36 (1.26 + 1.21 + 0.89); IV: 2.77 (0.92 + 0.92 + 0.93). Epigyne with short copulatory ducts (Figs 33–34).

Variation. Males with smaller palps also have smaller mastidia.

Distribution. Known only from the type locality (Ecuador).
