Remarks. This species was described on the basis of the adult female holotype, one adult female paratype and two adult male paratypes. The following characteristics appear in the original description and illustrations of the species, but do not agree with our observations of the female holotype: margin of epistome smooth between anteromedial and antero-lateral projections; setae j1, j6, z4-z6, s4-s5, r3, r5-r6, J1-J5, Z2-Z5, S1-S5 and Jv5 totally pilose, other setae smooth; genital shield smooth; peritrematal shield ornamented; lyrifissures present only on podonotal shield (one pair) and sternal shield (three pairs). No information was provided about the chelicera, hypostome, tritosternum and leg setal counts. The measurements provided in the original description referred to the length of the idiosoma (320–400), width of idiosoma (200–250), length of setae j1 (cited as i1) (20), j4 (cited as i3) (20), j5 (cited as i4) (20), r3 (cited as r5) (35), J1 (cited as I1) (17), J3 (cited as I3) (25), J4 (cited as I4) (25), Z3 (25), Z4 (30), Z5 (30), S4 (27), S5 (32), Jv5 (cited as V8) (30) and length of other ventral idiosomal setae (25).

For the adult male paratypes, the only characteristics provided referred to details of the spermatodactyl and ventral setae of femur, genu and tibia II, as well as measurements for length (380) and width (230) of the idiosoma.
