Description.
Size. Body length up to 2.92 mm.
Coloration. Ground colour pale white to yellow; eye patches dark blue; brown to blue-violet pigment present on whole dorsal body, antennae, legs, ventral tube, and manubrium. Some unpigmented irregular stripes or spots present on dorsal side of body (Figs 57, 58).
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). Sensory organ of Ant. III with two rod-like chaetae (Fig. 60). Sensory organ of Ant. II with 4–5 rod-like chaetae (Fig. 61). 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). Prelabral and labral chaetae as 4 / 5, 5, 4, all smooth, a 0, a 1 longer than a 2; labral papillae absent (Fig. 63). Basal chaeta on maxillary outer lobe slightly thicker than as apical one; sublobal plate with three smooth chaetae-like processes (Fig. 64). Lateral process (l. p.) of labial palp E differentiated, as thick as normal chaeta, with tip almost reaching apex of papilla E (Fig. 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).
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, 77 – 79). 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). Coxal macrochaetal formula as 3 / 4 + 1, 3 / 4 + 2 (Figs 70–72). Trochanteral organ with about 40–70 smooth chaetae (Fig. 73). 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).
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). 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). Abd. V with three sens (Fig. 79). 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); posterior face with 5–9 smooth and numerous ciliate chaetae (Fig. 81); lateral flap with 9–11 smooth and 16–25 ciliate chaetae (Fig. 82). Manubrial plate dorsally with 12–17 ciliate mac and 2–4 pseudopores (Fig. 83); ventrally with 39–60 ciliate chaetae on each side (Fig. 84). Dens with 37–66 smooth inner spines (Fig. 85). 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).
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, 4.
