Diagnosis.
This species is characterized by having all dorsal setae serrate, except J5, smooth; Seta z2 closer to j3 than to z3; ventrianal shield pentagonal; seta JV5 serrate and knobbed; calyx of spermatheca bell-shaped; atrium small, incorporated in calyx.
FEMALE. (
2 specimens
measured). Idiosomal setal pattern: 12A:8A/JV:ZV.
Dorsum. Dorsal shield, 282 (277–288) long and 156 (152–160) wide, reticulate. Apparently with 5 pairs of solenostomes. Setae j1 17 (14–19), j3 22 (21–24), j4 17 (16–18), j5 18, j6 23 (22–24), J2 26 (24–27), J5 9 (8–10), z2 19, z3 24, z4 25 (24–26), z5 20 (19–21), Z4 34 (32–37), Z5 50 (46–53),

R1
22 (21–24). Setae serrate and sharptipped, except J5, smooth; and Z5, knobbed
.
Peritreme. Extending to level of j1.
Venter. Sternal shield too weakly sclerotized to be illustrated and described; distances between ST1–ST3 53, ST2–ST2 51. Genital shield smooth; distance between ST5–ST5 50 (48–51). Ventrianal shield smooth, pentagonal, with anterior margin straight, 94 long, 67 (59–75) wide at level of ZV2, 60 (56–64) wide at level of anus, with 4 pairs of pre-anal setae (JV3 present); elliptical pre-anal pores slightly posterior and mesad of JV2. With 2 pairs of metapodal shields. Caudoventral setae smooth; except JV5, serrate and knobbed.
Chelicera. Movable digit 24 long, with 2 teeth; fixed digit 22 long, apparently with 3 to 4 teeth.
Spermatheca. Calyx bell-shaped, 13 (11–14) long,
10 in
diameter; atrium small, incorporated in calyx.
Legs. Macroseta knobbed: Sge IV 6, Sti IV 13, St IV 16. Leg IV with 4 and 3 knobbed setae on genu and tibia. Chaetotaxy: genu II: 2-2/1, 2/0- 1; genu III: 1-2/1, 2/0-1.
