Type-material examined: holotype male (Museum ID # Ar. - MHBU-ZJ070804 ), MHBU, precise collecting data see Jia et al (2010) .
Description of the females ( Fig.1b View Figure 1 ) Pedipalpal articles and chelicerae reddish brown. Caparace, abdomen and walking legs yellowish. Body setae straight and acicular.
Carapace. Smooth, 0.95–1.02 times as longer as broad ( Fig. 2b View Figure 2 ) with a total of 35–37 setae, including four on anterior margin and 12–14 on posterior margin; with four distinct simple eyes with flattened lenses; paired lyrifissures near eyes and posterior margin; epistome small, triangular.
Abdomen. Pleural membrane granulated. Tergal chaetotaxy: 12–16: 13–15: 14–16: 16–17: 15–17: 16–17: 18–19: 14–16: 13–16: 13–14: 6–8. haetotaxy of sternites IV–XI: 13–14: 16–19: 19–21: 19–20: 19–20: 18– 19: 16–18: 6–7. Anterior genital sternite with 3–6 medially situated setae, posterior genital sternite with a row of 13–16 longer setae on posterior sternite margin ( Fig. 2g View Figure 2 ).
Chelicerae. Cheliceral palm with seven setae, movable cheliceral finger with one sub-medial seta; fixed cheliceral finger with 6–7 teeth; movable finger with 8–10 small teeth of irregular shape ( Fig. 2b View Figure 2 ) serrula exterior with 41–44 lamellae; serrula interior with 38–40 lamella. Galea with two major bifurcations, from which each one being branched into four ( Fig.2c View Figure 2 ). Rallum eight bladed, all blades with anteriorlydirected spinules, basalmost the shortest, second and third ones at base almost at the same level(Fig, 2d)
Pedipalps. Apex of coxa rounded, with five setae. Trochanter 1.28–1.44, femur 2.49–2.74 times as long as broad, patella 1.70–1.72 times as long as broad, chela (with pedicel) 2.35–2.39 times as long as broad, chela (without pedicel) 2.25 times as long as broad, movable finger 0.77–0.91 times as long as hand (without pedicel). Venom apparatus present only in the fixed chelal finger, venom duct very short. Femur straight, depressed at base, smooth; patella claviform, glossy ( Fig. 2f View Figure 2 ).Chelal fingers shorter than palm. Fixed chelal finger with eight trichobothria, movable finger with four ( Fig. 2e View Figure 2 ), eb and esb situated on lateral margin of hand; ist situated near ib; st slightly closer to t than to sb. Fixed chelal finger with 63–72 rounded teeth, while movable finger bears 62–69 rounded teeth.
