Anterior and lateral parts of dorsal head with blue pigment. Blue pigment also present on each tergite and coxa ( Figs 35−36 View FIGURES 35−36 ).

Body chaetae long and leaf-like ( Fig. 37 View FIGURES 37−40 ).

Antenna 0.41−0.45 times body length; antennal segment ratio as I: II: III: IV = 1: 1.70−2.22: 1.60−2.00: 2.07−2.85. Apical bulb of Ant. IV bilobed ( Fig. 41 View FIGURES 41−48 ). Distal part of Ant. III with three rods ( Fig. 42 View FIGURES 41−48 ). Distal part of Ant. II with two rods ( Fig. 43 View FIGURES 41−48 ). Eyes 8+8, G and H smaller than others, interocular chaetae as p, s, t mes ( Figs 38 View FIGURES 37−40 , 44 View FIGURES 41−48 ). Dorsal cephalic chaetotaxy with four antennal (An), four median (M) and eight sutural (S) mac ( Fig. 44 View FIGURES 41−48 ). Prelabral and labral chaetae as 4/5, 5, 4, prelabral chaetae ciliate, other smooth, four labral papillae with one minute denticle each ( Fig. 45 View FIGURES 41−48 ). Lateral process (l.p.) of labial papilla E differentiated, thicker than normal chaeta with tip reaching apex of papilla E ( Fig. 46 View FIGURES 41−48 ). Labial triangular chaetae as MREL1L2, all ciliate and R 0.50−0.55 length of M ( Fig. 47 View FIGURES 41−48 ). Subapical chaeta of maxillary outer lobe thin, subequal to apical one; three smooth hairs on sublobal plate ( Fig. 48 View FIGURES 41−48 ).

Th. II with four (m1, m2, m2i, m2i2) mac on T1 area, five (a5, m4, m4i, m4p, m5) mac on T2 area, 24−30 posterior mac, one ms and two se on each side. Th. III with 32−36 mac and two se ( Fig. 49 View FIGURES 49−51 ). Trochanteral organ with 11−13 smooth spiny chaetae ( Fig. 50 View FIGURES 49−51 ). Unguis with four inner teeth, one pair located 0.57−0.59 from base of inner edge of unguis, distal unpaired two respectively at 0.71−0.76 and 0.83−0.91 distance from base. Unguiculus acuminate and outer edge serrate. Tenent hair thick with its tip clavate, longer than inner side of unguis ( Figs 39 View FIGURES 37−40 , 51 View FIGURES 49−51 ).

Abd. IV 2.50−4.28 times Abd. III in dorsal axial length. Abd. I with nine (a2, a3, a5, m2−4, m2i, m4i, m4p), ms antero-external to se. Abd. II with two (a2, a3) mac on A1 arae, four (m3, m3e, m3ea, m3ep) mac on A2 area, one (m5) lateral mac and two se. Abd. III with two (a2, a3) mac on A4 area, one (m3) mac on A5 area and three (am6, pm6, p6) lateral mac, one ms and two se ( Fig. 52 View FIGURE 52 ). Abd. IV with seven central mac, 10 lateral mac ( Fig. 53 View FIGURES 53−59 ). Abd. V with three se ( Fig. 54 View FIGURES 53−59 ). Anterior face of ventral tube with 11−14 ciliate chaetae, line connecting proximal (Pr) and external-distal (Ed) mac oblique to median furrow ( Fig. 55 View FIGURES 53−59 ); posterior face not clearly seen; lateral flap with 2−3 smooth chaetae and 7−8 ciliate chaetae ( Fig. 56 View FIGURES 53−59 ). Manubrial plate dorsally with 6−7 ciliate chaetae and three pseudopores ( Fig. 57 View FIGURES 53−59 ); ventrally with 10−11 ciliate chaetae on each side ( Fig. 58 View FIGURES 53−59 ). Uncrenulated dens 2.43−3.21 times as mucro in length. Mucro bidentate, two teeth subequal and tip of basal spine reaching subapical tooth ( Figs 40 View FIGURES 37−40 , 59 View FIGURES 53−59 ).

Ecology. Found in rotten leaf, mainly composed of Pinus tabuliformis , Quercus liaotungensis and Cotoneaster zabelii .

Etymology. Named after its locality: Gansu Province.

Remarks. The new species is the second Himalanura species reported from China and can be distinguished from the first Chinese species of the genus, H. shanxiensis Zhou & Ma, 2020 in colour pattern, body macrochaetotaxy and other characters. It is similar to these species in macrochaetotaxy of Abd. III: H. baijali Baquero, Mandal & Jordana, 2014 , H. bulunkuli Tshelnokov, 1977 , H. gelmani Tshelnokov, 1987 , H. himachalensis Baquero & Jordana, 2015 (in: Baquero et al, 2015), H. martynovae Tshelnokov, 1977 and H. tundricola Tshelnokov, 1987 , but can be separated from them by apical bulb on antenna, macrochaetotaxy of dorsal head, Th. II−III, Abd I−II and IV ( Table 2 View TABLE 2 ).
