Spermatheca. Calyx funnel-shaped, 29 (23–37) [30] long; atrium c-shaped.

Legs. Knobbed or sharp-tipped macroseta: St IV 21 (19–22) [19]. Chaetotaxy: genu II: 2-2/1, 2/0-1; genu III: 1-2/1, 2/0-1.

MALE. (Specimens measured. South Africa: 1 paratype)

Dorsum. Dorsal shield and setal pattern as in female, 253 long and 150 wide. Setae j1 17, j3 22, j4 16, j5 16, j6 18, J2 24, J5 10, z2 18, z3 20, z4 22, z5 18, z6 19, Z4 30, Z5 30, s4 25, s6 24, S2 26, S4 24, S5 22, r3 21, R1 21.

Peritreme. Extending to level of j1.

Venter. Ventrianal shield subtriangular, mostly smooth with few striae anteriorly; because of its position on the microscope slide, length not possible to measure, 122 wide at the anterior corners; with 4 pairs of preanal setae (JV1, JV2, JV3 and ZV2), 4 pairs of lyrifissures (1 anterior to JV1, 1 lateral and almost in line with JV1, 1 lateral and posterior to JV1 and 1 lateral and lightly posterior to ZV2), 1 pair of round preanal pores posteromesad to JV2. Caudoventral setae smooth and sharp-tipped.

Spermatodactyl. Curved distally with a small pointed process near curve, ending in a knob; shaft 19 long.

Legs. Knobbed or sharp-tipped macroseta: St IV 18. Chaetotaxy of genua II and III same as in female.
