Diagnosis. Mallinella brachiata sp. nov. can be recognized by the reduced dorsal pattern on the opisthosoma ( Figs 108–109 View FIGURES 108–113. 108 ). Males are distinguishable by the lack of an oblique mesal ridge and of an apico-prolateral process on the TA; a mesal tooth on the TA being largest among all males of the tuberculata -group. Females can be easily recognized by the W-shaped epigynal plate.

Etymology. The specific epithet is a latinized adjective of the Greek noun (βραχƖων = arm) and refers to an apico-retrolateral arm on the TA.

Description. Male (holotype). Total length 7.53; prosoma 3.74 long, 3.08 wide; opisthosoma 3.79 long, 2.86 wide. Eye sizes and interdistances: AME 0.20, ALE 0.16, PME 0.15, PLE 0.16, AME–AME 0.12, AME–ALE 0.14, PME–PME 0.14, PME–PLE 0.26; MOQ: 0.52 long, 0.38 anterior width, 0.40 posterior width. Leg measurements: I 10.46 (2.87, 3.22, 2.30, 2.07), II 10.23 (2.64, 3.22, 2.53, 1.84), III 10.35 (2.76, 3.10, 2.76, 1.72), IV 12.00 (2.80, 3.92, 3.69, 1.59).

Coloration ( Fig. 108 View FIGURES 108–113. 108 ). Carapace reddish brown anteriorly, orange-brown posteriorly. Chelicerae dark brown. Sternum yellowish orange. Legs yellowish. Dorsum of opisthosoma sepia. Dorsal pattern: first and second pairs represented by two short, transverse bands; third pair by triangular patch; from fourth pair onwards fused, forming pale anal ring. Dorsal scutum yellowish brown, narrowed, edge vaguely defined.

Palp ( Figs 147–151 View FIGURES 147–155. 147–151 ). RTA digitiform in ventral view, gently curved in lateral view, apex sharply pointed; dorsal tubercle triangular, apex blunt. Cymbial fold approximately 1/3 length of cymbium. Tegular spine relatively large, broad at base, apex sharply pointed, directed anteriad. Membranous area on tegulum with inflated median hump, clearly visible in lateral view. TA elongated, terminally with broad and sharply pointed apico-prolateral fold; apico-prolateral process indistinct; apico-retrolateral arm curved in ventral view, pointed dorsad in lateral view; mesal tooth triangular, indented in prolateral view. Embolus originating at 270°, with shallow longitudinal groove over entire length; mesal ridge with triangular subapical flange; lateral ridge longer than mesal one, apex truncated.

Female (paratype, MHNG TH–11). Total length 8.96; prosoma 4.25 long, 2.80 wide; opisthosoma 4.07 long, 3.09 wide. Eye sizes and interdistances: AME 0.17, ALE 0.15, PME 0.15, PLE 0.15, AME–AME 0.14, AME–ALE 0.28, PME–PME 0.20, PME–PLE 0.37; MOQ: 0.56 long, 0.46 anterior width, 0.48 posterior width. Leg measurements: I 9.29 (2.68, 2.80, 2.35, 1.45), II 8.25 (2.64, 2.80, 1.68, 1.13), III 9.34 (2.71, 2.97, 2.19, 1.45), IV 10.01 (2.80, 2.88, 2.68, 1.63).

Legs yellowish, femora distally and proximally with dark brown annulation. Dorsum of opisthosoma dark sepia. Dorsal pattern reduced, represented by three small triangular patches and large anal ring.

Genitalia ( Figs 116 View FIGURES 114–121. 114 , 152–155 View FIGURES 147–155. 147–151 ). Epigynal plate W-shaped, with deep and broad anterior median incision. Spermathecae digitiform, abruptly curved backwards.
