Measurements. Body length 445 (holotype), 385–425 (three paratypes); body width 310 (holotype), 285–290 (three paratypes).

Integument. Body color yellow-brownish to brown. Surface of lamellae with rugged granules densely. Podotectum I with thin striae parallel to anterior margin. Process of pteromorphs with irregular granules. Notogaster with foveolae densely, medial-posterior border with irregular circular sculpture.

Prodorsum ( Figs 24–28, 31 ). Rostrum rounded. Longitudinal ridge present near rostrum. Lamellae broad, fused basally. Lamellae cusp with pointed lateral tooth. Lamellar setae (35) setiform, short and thick. Rostral setae (79) with

Notogaster ( Figs 24, 31–32 ). Dorsosejugal suture angular weakly medially. Process of pteromorphs pointed apically. Lateral corner of pteromorphs with well pointed process. Ten pairs of notogastral setae thick, setiform and smooth. Setae c, la, lm, lp and h 3 (38–50) longest; p 3 shortest (17); others of medium size (27–33). Sacculi Sa oval, indistinct; S 1 oblonged, well developed; S 2 rounded, very small; S 3 hardly visible. Lyrifissyre im S-shaped. Opisthosomal gland openings located lateral-posteriorly to h 3.

Gnathosoma ( Figs 25, 31 ). Subcapitulum: 54 × 96. Setae h (15), m (25) and a (10) setiform, smooth.

Epimeral region ( Figs 25, 31 ). Epimeral setal formula 3–1–3–3, setiform, smooth. Setae 1a, 1c and 3b only alveoli present; 2a (13) shortest; 1b, 3a and 3c (21–29) longest; 4a, 4b and 4c (15–17) middle. Setae 3c and 4c inserted laterally. Pedotecta II triangular. Discidia thorn-like.

Anogenital ( Figs 29–30 ). Six pairs of genital setae (g 1 – g 2 19–23, g 3 – g 6 10–16), one pair of aggenital (29). Two pairs of anal (8–10) and three pairs of adanal (10–22) setiform, smooth. Lyrifissures iad located in paranal position, near to anal plates, anterior to ad 3.

Legs ( Figs 33–36 ). Monoda ctylous. Generally similar to other species of Achipteriidae . Formulae of leg setation and solenidia: I (1–5–2–4–20) [1–2–2], II (1–5–2–3–15) [1–2–2], III (2–3–1–3–15) [1–1–0], IV (1–2–2–3–12) [0–1–0]. Seta s of tarsi II and I thick, with strong spines unilaterally. Famulus short, blunt-ended.

Material examined. Holotype male, China, Yunnan, Baoshan, Longyang District , Mt. Gaoligong (25º17’N, 98º48’E), 7 May 2011, Li-Xia Xie , in leaf litter. Paratypes 3 males, same data as holotype. All deposited in Institute of Entomology , Guizhou University , Guiyang City , China ( GUGC) .

Distribution. China (Yunnan).

Etymology. The specific name “ gaoligongensis ” refers to the type locality, Mt. Gaoligong.
