Diagnosis. Female dorsal shield suboval, attenuated between setae s4 and Z1; surface distinctly imbricate. Dorsal setae smooth and pointed, except Z5 barbed. Setae j3 twice as long as j1; setae j5 0.8 times as long as j4; setae r3 1.5 times as long as R1; setae S2, Z4 and Z5 similar in length. Dorsal adenotaxy reduced, with two pairs of dorsal solenostomes (gd4, gd6); poroidotaxy with the complement of sixteen poroids. Peritremes broad (8 µm wide), reaching the space between setae j1–j3. Sternal shield striated longitudinally, with three pairs of setae; setae st4 on piriform plates placed close to the posterolateral projections of sternal shield. Ventrianal shield pentagonal, with laterals concave, narrower at the level of pre-anal pores; transversally striated in the anterior part, almost smooth posteriorly; three pairs of pre-anal setae; pre-anal pores punctiform, well separated each other (42–55), posterior or posteroantiaxial to setae JV2. Atrium of the spermatheca globose and oval-shaped, longitudinally forked, almost as wide as base of calyx; calyx subconical, 10–12 long, 9–10 wide at the junction with the vesicle. Cheliceral fixed digit with three subapical teeth; movable digit with one small denticle, difficult to discern in some females. Genu II with eight setae (2 2/0, 2/1 1); one short (25–29), curved and pointed macroseta on basitarsus IV. Male spermatodactyl T-shaped (15 long); ventrianal shield striated, forming several cells on the anterior part; six pairs of pre-anal setae; pre-anal pores punctiform. Same dorsal adenotaxy, cheliceral dentition and leg setation than in female.
