Head. Antenna not annulated and 0.59–0.64 times length of body. Ratio of Ant. I – IV as 1.00 / 1.28–1.40 / 1.11 – 1.36 / 2.00 – 2.25. Distal part of Ant. IV with many sensory chaetae and normal ciliate chaetae, apical bulb bilobed (Fig. 59 View Figures 59–65 ). Sensory organ of Ant. III with two rod-like chaetae (Fig. 60 View Figures 59–65 ). Sensory organ of Ant. II with 4–5 rod-like chaetae (Fig. 61 View Figures 59–65 ). Eyes 8 + 8, G and H smaller than others, interocular chaetae as p, r, t mes. Dorsal chaetotaxy of head with four antennal (An), five median (M) and eight sutural (S) mac (Fig. 62 View Figures 59–65 ). Prelabral and labral chaetae as 4 / 5, 5, 4, all smooth, a 0, a 1 longer than a 2; labral papillae absent (Fig. 63 View Figures 59–65 ). Basal chaeta on maxillary outer lobe slightly thicker than as apical one; sublobal plate with three smooth chaetae-like processes (Fig. 64 View Figures 59–65 ). Lateral process (l. p.) of labial palp E differentiated, as thick as normal chaeta, with tip almost reaching apex of papilla E (Fig. 65 View Figures 59–65 ). Labial base with MRel 1 L 2, M rarely smooth, R ciliate and 0.50–0.69 length of M, chaetae e and l 1 smooth, L 2 ciliate; some post-labial chaetae (G 1–4, H 2–4, rarely X, X 3 and 1–2 unnamed chaetae) smooth (Figs 66–68 View Figures 66–68 ).

Thorax. Tergal ms formula on Th. II – Abd. V as 1, 0 / 1, 0, 1, 0, 0, sens as 2, 2 / 1, 2, 2, 23–37, 3 (Figs 69 View Figures 69–76 , 77 View Figure 77 – 79 View Figures 79–86 ). Th. II with four medio-medial (m 1, m 2, m 2 i, m 2 i 2), three medio-sublateral (m 4, m 4 i, m 4 p), 32–42 posterior mac. Th. III with 45–57 mac (Fig. 69 View Figures 69–76 ). Coxal macrochaetal formula as 3 / 4 + 1, 3 / 4 + 2 (Figs 70–72 View Figures 69–76 ). Trochanteral organ with about 40–70 smooth chaetae (Fig. 73 View Figures 69–76 ). All tenent hairs pointed and 0.53–0.68 length of inner edge of unguis; unguis with three inner teeth, basal pair located at 0.29–0.35 distance from base of inner edge of unguis, unpaired tooth at 0.59–0.62 distance from base; unguiculus lanceolate, outer edge slightly serrate (Figs 74–76 View Figures 69–76 ).

Abdomen. Range of Abd. IV length as 6.43–7.50 times as dorsal axial length of Abd. III. Abd. I with 11 (sometimes 12) (a 1 a, a 1–3, m 2 i, m 2–4, m 4 i, m 4 p and a 5, an unnamed mac sometimes present) mac. Abd. II with six (a 2, a 3, m 3, m 3 e, m 3 ea, m 3 ep) central, one (m 5) lateral mac. Abd. III with two (a 2, m 3) central, four (am 6, pm 6, m 7 a, p 6) lateral mac (Fig. 77 View Figure 77 ). Abd. IV with two (as, ps) normal sens, 9–12 anterior, 5–6 (A 5–6, B 5–6, Ae 7, A 4 sometimes present) posterior and 19–23 lateral mac (Fig. 78 View Figure 78 ). Abd. V with three sens (Fig. 79 View Figures 79–86 ). Anterior face of ventral tube with 44–55 ciliate chaetae on each side, line connecting proximal (Pr) and external-distal (Ed) mac oblique to median furrow (Fig. 80 View Figures 79–86 ); posterior face with 5–9 smooth and numerous ciliate chaetae (Fig. 81 View Figures 79–86 ); lateral flap with 9–11 smooth and 16–25 ciliate chaetae (Fig. 82 View Figures 79–86 ). Manubrial plate dorsally with 12–17 ciliate mac and 2–4 pseudopores (Fig. 83 View Figures 79–86 ); ventrally with 39–60 ciliate chaetae on each side (Fig. 84 View Figures 79–86 ). Dens with 37–66 smooth inner spines (Fig. 85 View Figures 79–86 ). Mucro bidentate with subapical tooth larger than apical one; tip of basal spine reaching apex of subapical tooth; distal smooth section of dens almost equal to mucro in length (Fig. 86 View Figures 79–86 ).

Etymology.

Named after its locality: Huaping Natural Reserve, Guangxi Guangxi Zhuang Autonomous Region.

Ecology.

Found in the leaf litter.

Remarks.

The new species is very similar to H. guangxiensis sp. nov. and H. acutus Jing & Ma, 2022 in the colour pattern, smooth post-labial chaetae, inner teeth on unguis and central chaetae on Abd. IV posteriorly, but can be separated from them by the tenent hair, central chaetae on Abd. IV anteriorly and smooth chaetae on the posterior face of the ventral tube. The detailed character comparisons are listed in Tables 3 View Table 3 , 4 View Table 4 .
