Description. Male. Total length 5.8–6.5. Holotype total length 5.8, cephalothorax 3.0 long, 2.4 wide, 1.5 high; abdomen 3.2 long, 2.4 wide, 2.3 high. AME diameter 0.23. ALE 1.0, PME 0.89, PLE 0.89 times AME diameter. AME separation 0.44 times their diameter, PME separation 0.69 times their diameter. AME-ALE separation 0.56 times AME diameter, PME-PLE separation 0.88 times PME diameter. Clypeus height 2.0 times AME diameter. Sternum 1.6 long, 1.5 wide, with distal end sharp. Labium wider than long. Chelicerae with 5 prolateral and 4 retrolateral teeth ( Fig. 17 ). Cheliceral stridulatory striae absent. Legs with black annuli. Femora I–IV with 1 dorsal setae and femur I with another 1 prolateral seta. Patellae I–IV with 2 dorsal setae at the base and distally respectively. Tibiae I–IV with numerous setae. Metatarsi I–IV with 1 trichobothrium dorsally and Tm I 0.27. Lengths of legs: I 16.3 (4.3+5.3+4.7+2.0), II 13.2 (3.5+4.3+3.6+1.8), III 8.1 (2.7+3.0+2.2+1.2), IV 10.7 (3.0+3.4+2.9+1.4). Leg formula: I, II, IV, III. Femur I 1.43 times length of cephalothorax. Abdomen oval, dorsum with black and silvery patterns. Tibia of male palp with about 10 macrosetae and retrolateral trichobothria, especially with a thumb–shaped spine. Paracymbium distinct. PCS modified into a shallow cavity. CP with a separated thumb–shaped apophysis and a line of about 4 setae and every seta with distinct tubercle. Embolus short, broad and with sharp distal end. A sharp apophysis situated at the base of embolus. PEP forming an indistinct gap distally which encloses the distal end of embolus. Embolic flap film-like, arising from the area where the embolic process (PEP) connects to the embolus (Fig. 22). Conductor distinct, membranous ( Figs 18 –21). Weintrauboa pollex sp. nov. , 21.

The specimen from September 26 measured in total length 7.7, cephalothorax 3.0 long, 2.0 wide, 2.0 high; abdomen 4.7 long, 3.0 wide, 3.2 high. AME diameter 0.2. ALE 1.0, PME 0.88, PLE 1.0 times AME diameter. AME separation 0.19 times their diameter, PME separation 0.45 times their diameter.

Chelicerae with 4 prolateral and 4 retrolateral teeth (Fig. 23). Tm I 0.28. Lengths of legs: I 16.3 (3.2+3.8+3.0+1.7), II 13.2 (2.8+3.3+2.6+1.5), III 8.1 (2.2+2.3+1.9+1.1), IV 10.7 (2.6+2.8+2.4+1.3). Leg formula: I, II, IV, III. Femur I 1.27 times length of cephalothorax. Abdomen with black and silvery patterns (Figs 24–25). Other characters similar to those of male. Epigynum short. Copulatory openings situated on the posterior of the dorsal epigynum. Spermathecae fist–shaped, widely separated by copulatory ducts. Fertilization ducts oriented posteriorly (Figs 26–29).
