Palp

Cymbium with a projection; prolateral side of paracymbium unpigmented and unsclerotized, numerous setae and spines at the tip of paracymbium ( Fig. 6F, G ). Contrategulum has two marginal apophyses with smooth margin and blunt distal end ( Fig. 6H ). Tegulum with a dentate, wide edge ( Fig. 6F, G ). Conductor with a spiniform apex and a small apophysis at posterior part, parallel with embolus ( Fig. 6G ). Embolus largely sclerotized, with a wide and flat opening, and distal embolus slightly sclerotized ( Fig. 6G ).

Female ( Fig. 6A ). Carapace and opisthosoma of female similar to male, except coloration lighter than male; chelicerae robust, with promargin of cheliceral groove with between ten and 12 strong denticles of variable size; legs with strong hairs and spines; opisthosoma with 12 tergites, similar to male; seven spinnerets. Measurements: BL 10.68–14.48, CL 5.48–7.05, CW 4.52– 6.00, OL 5.77–7.62, and OW 4.13–5.68; ALE > PLE > PME > AME; palp 9.51 (3.40 + 1.70 + 2.00 + 2.41), leg I 11.43 (3.85 + 1.95 + 2.08 + 2.25 + 1.30), leg II 11.08 (3.40 + 1.95 + 1.96 + 2.45 + 1.32), leg III 11.81 (3.46 + 2.05 + 1.92 + 2.70 + 1.68), and leg IV 17.46 (4.95 + 2.48 + 3.05 + 4.68 + 2.30).

Posterior part of genital area rectangular ( Fig. 6B– E ), with pair of receptacular clusters with genital stalks ( Fig. 6B, C ), or with paired receptacular clusters fused into a big cluster ( Fig. 6D, E ).

Variation
