Dorsal shield 430 μm long and 215 μm wide, with deep lateral incisions, bearing 17 （16） pairs of simple setae on anterior region and 14 pairs of simple setae on posterior region, not reach insertion of next seta, F2 shorter, S8 the shortest. Dorsal cuticle setae 10 pairs. Sternal shield longer than wide, with 3 pairs of setae and 3 pairs of pores. MSt situated on cuticle behind the shield. Genital shield narrow, slightly expanded posteriorly, genital setae situated on cuticle out of the shield. Anal shield broadly oval, Ad lying behind level of middle of anus, slightly longer than anus, PA slightly longer than Ad. Metapodal shields 1 pair.
