Figs 10 F, 11F, 12F, 13F, 14A, 16E

Type material. Female holotype from Serra da Gandarela , Rio Acima, Minas Gerais, Brazil (20º5´31” S, 43º41’0” W, 1636m), 14.II.2015, A.J. Santos coll., deposited in UFMG 16876 .

Etymology. The specific name is taken from the type locality, Serra da Gandarela , a mountain range that contribute to the aquifer system of the central Minas Gerais mountains, and which is threatened by mining activities.

Diagnosis. Females can be distinguished by the sinuous anterior ridge, with the middle part projected anteriorly, by the ACT very coiled, and by the secondary spermathecae about two thirds the diameter of the primary ones ( Figs 10 F, 11F, 12F, 13F).

Legs and palps brown, lighter in patellae, tibiae, metatarsi and tarsi. Femur I with a lighter area in the prolateral proximal part. Sternum and labium brown. Endites light brown with white anterior border. Opisthosoma pale gray. Eye sizes and interdistances: AME 0.08, ALE 0.1, PME 0.07, PLE 0.08, AME–AME 0.06, AME–ALE 0.02, ALE–PLE 0.05, PME–PME 0.06, PME–PLE 0.06. MOQ 0.48 wide. Leg spination: femora: I, II d1-1-1, p0-0-1; III d1-1-1, r0-1-1, p0-1-1; patellae: III, IV p0-1-0, r0- 1-0; tibiae: I v0-0-1p; II vlr-2-0; III, IV d1-0-0, p1-1-0, v1 p-2-2, r2-2-0; Metatarsi: I, II v2 -0-0; II, IV p1d-2- 1v, v2-2 - 2, r1d-1d-2.

Male: Unknown.

Material examined. Only the holotype.
