Shape of dorsal shield oblong, with length 440-460 and width 280-310 at level of the coxae II (n=3), micropunctation on anterior and lateral surface with reticulate sculptural pattern. Majority of setae on dorsal shield long and pilose in distal half, except setae j1 and z1 which are short, smooth and spine-like, and J5 with pilose margins for entire length. Length of dorsal setae: j1 and z1= 8-9, j2 = 22-24, j2, s2, Z2, Z5 and S5 = 24-26, j3, j4, j6, z2, z4, z5, z6, s4, s6, J2, Z1, Z4, S1, S2, S4 = 30-32, j5, s5, s6, r3, r3, r4 = 34-35, J5 = 16. Dorsal shield with four pairs of lyrifissures (close to z1, s6, S5 and between Z2 and S4), ten pairs of gland pores (close to j3, j4, s5, j6, z6, Z1, Z2, S4, Z4 and two close to J2), and four pairs of microspicules (close to r2, Z2, Z4 and Z5). Peritreme reaches the bases of setae z1.</paragraph>
Venter (Figure 2). Sternal shield 87-95 long and 100-110 wide at level of coxae II, bearing 3 pairs of needle-like setae and two pairs of lyrifissures. Posterior margin
sternal shield concave. Surface with linearly arranged punctures. Measurements of setae: St1 = 34-36, St2 = 30-32 and St3 = 26-28. Cuticle with a thin punctuation. Metasternal seta on metasternal platelet with length 20-23. Posterior margin of genital shield straight. Genital shield with length 75-78 and width 89-93. The length of seta on genital shield 23-26. Apodemes between ventrianal and genital shields absent. Ventrianal shield pentagonal with length 158-162 and width at level of Jv2 145-148, surface reticulated with linearly arranged punctures. Three pairs of ventrianal setae 22-25 long, needle-like, adanal setae needle-like and 22 long. Post-anal seta similar in shape and length to adanal setae. Opisthogaster bearing more than twelve pairs of slightly pilose setae (12-19 long). Sperm access system not visible.
