Type material.

Holotype: ♂, China, Yunnan: Tengchong County, Jietou Township, 8# boundary post of Yakou (25°80.894'N, 98°62.080'E, 2890 m), 23 May 2006, Xingping Wang, Xianjin Peng leg.

Etymology.

The specific name refers to the type locality; adjective.

Diagnosis.

This new species is somewhat similar to Hitobia yaginumai Deeleman-Reinhold, 2001 (see Deeleman-Reinhold 2001: figs 868-874), especially in opisthosoma having a large dorsal scutum, retrolateral tibial apophysis bearing a tuft of long setae on the base, male palp with a obvious conductor, but can be distinguished from the latter by: 1) embolus erect, the tip reached to the position of 11:00 o’clock approximately (Figs 3, 7) versus encircling along the top of bulb prolaterally, the tip reached to the position of 2:00 o’clock in Hitobia yaginumai ; 2) conductor lamellate in retrolateral view (Figs 4, 8) versus almost semicircular in Hitobia yaginumai ; 3) retrolateral tibial apophysis hornlike and its apex only extending to the quarter of cymbium in retrolateral view (Figs 4, 8) versus hook-like and its apex extending about to the middle part of cymbium in Hitobia yaginumai ; 4) abdominal dorsum only with one transverse white stripe (Fig. 1) versus with two additional short longitudinal white stripes on each side except for one transverse white stripe in Hitobia yaginumai ; 5) chelicerae with 3 promarginal teeth (Fig. 6) versus 2 in Hitobia yaginumai .

Description.

Male: Total length 5.15. Prosoma 2.29 long, 1.67 wide. Opisthosoma 2.72 long, 1.52 wide. Clypeus 0.05 high. Carapace dark brown, long oval, widest at coxae II and III, covered with some white hair. Cervical grooves, fovea and radial grooves dark brown. AER and PER both slightly recurved, wider posteriorly (Fig. 5). Eyes sizes and interdistances: AME 0.08, ALE 0.08, PME 0.07, PLE 0.09, AME–AME 0.04, AME–ALE 0.01, PME–PME 0.09, PME–PLE 0.09, ALE–PLE 0.14. MOA anterior width 0.18, posterior width 0.22, length 0.25. Chelicerae brown, with 3 promarginal teeth and 1 retromarginal (Fig. 6). Endites yellowish brown, almost parallel (Fig. 2). Labium yellowish brown, longer than wide, ligulate (Fig. 2). Sternum colored as labium, covered with some dark bristles, anterior straight and posterior subacute (Fig. 2). Legs femur, coxae I and II dark brown, others yellowish brown. Trochanters I and II without ventral notch, trochanters III and IV with a shallow ventral notch. Legs spinnation: femur: I, II, III d1-1-0, r0-0-1; IV d0-0-1; patella: I, II, III p0-1-0; IV p0-1-0; tibia: I v1-1-1; II v1-1-1; III d1-0-0, p1-0-0, v1-0-0, r1-1-1; IV d1-0-0, v1-0-1, r0-1-0; metatarsi: I v1-0-0; II v1-0-0, p1-0-0; III d1-0-0, p0-1-0, v1-0-0; IV d1-1-0, p0-1-0, r0-1-0, v1-1-0. Legs length: I 4.65 (1.31, 1.72, 1.02, 0.60), II 4.61 (1.29, 1.70, 1.02, 0.60), III 4.28 (1.02, 1.45, 1.21, 0.60), IV 5.84 (1.71, 2.00, 1.53, 0.60). Dorsum of opisthosoma (Fig. 1) dark brown, long oval, with a large scutum about four-fifths of the whole abdominal length and one transverse white stripe posteriorly, covered with white thin hair. Venter brown.

Male palp (Figs 3-4, 7-8): tibia short, with several long prolatral macrosetae, the retrolateral apophysis hornlike and bearing a tuft of long and curved macrosetae on the base. Bulb elongated, widest at middle part. Embolus thin and short, originating from the prolateral top of bulb, erect, the tip reached to the position of 11:00 o’clock approximately in ventral view. Conductor large relatively, membranous, situated retrolaterally at embolus, lamellate in retrolateral view.

Female: Unknown.
