Figs 10 , 58–59

Type locality. China, Qinghai, Xining.

Material examined. Female on slide, China: Qinghai Province: Xining City: hillside western to Grain Reserve Station, under stones, 1.viii.2009, C Ge leg. (# C9588); female on slide and 2 in alcohol, China, Hebei Province, 39.106°N, 114.377°E, alt. 757 m, 16.vii.2012, among leaves along the streamlet, Z Chen leg. (# HB07161); female on slide and 1 in alcohol, China, Neimenggu Province, the grassland along 105 national highway, 41.447°N, 113.298°E, alt. 1478 m, 16.vii.2012, Z Chen leg. (#NM07233); female on slide, China, Neimenggu Province, Balinyou Qi, marshy grassland, 41.418°N, 118.695°E, alt. 1196 m, 7.viii.2014, Z Chen leg. (# 14NM2).

Additions to original description. Two internal sens of Ant. III organ rod-like. Clypeus chaetae 9, four lateral ones smaller and ciliate ( Fig. 58 ). Labial chaetae as mRel1l2, all smooth except R. Post-labial chaetae H1, X, X2–4 ciliate; X3 sometimes absent. Chaetae along cephalic groove 9, the first (G1) and the third smooth and others ciliate. Lateral flap of ventral tube 6–8 smooth chaetae ( Fig. 59 ). S-chaetotaxic formula 2, 2/1, 2, 2, -, 3 sens, 1, 0/1, 0, 0 ms. Mac m 3ei on Abd. II absent in two newly examined specimens.

Distribution. Qinghai, Neimenggu, Hebei.

Remarks. The chaetotaxic pattern of Abd. I, 5+5 mac with m 2i absent, is unique in the genus. Additional chaetae around H4 were not observed in the newly collected specimens. The differences among three 3+3 eyed species from China were discussed in detail by Wang & Christiansen (2000).
