Venter ( Figure 31 ): epimeral formula 3-1-4-1. Genital area with only four pairs of aggenital setae. Three pairs of anal setae, ps 1–2 dorsally situated. Cupule ih mediolaterally located on an imaginary line connecting fourth pair of aggenital setae and ps 3. All ventral setae and aggenital setae stout, except for the slender ag 4.

Gnathosoma ( Figure 32 ): palp chaetotaxy (tarsus to trochanter) 5-1-1-0. A solenidion may be present but could not be detected. Palp tibiotarsus with seta pζ stout and apparently forked distally, seta d setose.

Legs ( Figures 33, 34 ): chaetotaxy of leg segments: tarsi 8(ω)-6(ω)-5-5, tibiae 4(ϕ)-2-2-2, genua 3-3-2-1, femora 3-2-2-2, trochantera 1-1-1-0.
