Etymology. The specific name comes from the Latin adjective “ mutica ”, meaning “blunt”, and refers to the shape of the tip of cymbial ectobasal process.

Diagnosis. This species can be distinguished from other Wolongia species by the combination of the following characters: 1) conductor and embolus almost covering the whole genital bulb in ventral view ( Figs 19 B, 21A); 2) cymbial ectobasal process with a blunt tip, bending to dorsum in retrolateral view ( Figs 19 C, 21B); 3) cymbial base with a denticle retrolaterally ( Figs 19 C, 21B); 4) atrium slightly longer than wide ( Figs 20 B, 22A); 5) spermatheca membranous, three times longer than wide in dorsal view ( Figs 20 C, 22B). Females of this species are very similar to W. odontodes in dorsal view of female genital organ ( Figs 20 C, 22B, 24D, 26C), but can be distinguished from the latter by: 1) atrium slightly longer than wide versus wider than long in W. odontodes ( Figs 24 C, 26B); 2) spermatheca three times longer than wide in dorsal view versus almost as long as wide in W. odontodes ( Figs 24 D, 26C).

Description. Male (holotype): Total length 2.09. Cephalothorax 0.90 long, 0.77 wide. Abdomen 1.25 long, 0.90 wide. Carapace yellowish-brown, with slightly dark margins. AME 0.07, ALE 0.08, PME 0.10, PLE 0.09, AME-AME>AME-ALE (0.05>0.04), PME-PME=PME-PLE (0.06), LMOA 0.23, AWMOA 0.18, PWMOA 0.23. Clypeus 0.10. Chelicerae yellowish-brown, with 5 retromarginal teeth ( Figs 1 F, 21D). Labium dark-brown, width 0.23, length 0.11. Coxae brown. Legs yellow-brown. Leg measurements: I 5.65 (1.61, 1.85, 1.58, 0.61), II 4.22 (1.25, 1.40, 1.08, 0.49), III 2.40 (0.75, 0.74, 0.56, 0.35), IV 3.69 (1.05, 1.03, 0.85, 0.76). Abdomen oval, widest medially. Dorsum silvery-white, with a brown median stripe with wave-shaped margins ( Fig. 19 A). Venter brown, with one pair of white longitudinal stripes. Cymbial ectobase with a short denticle and a robust process bending to dorsum in retrolateral view ( Figs 19 C, 21B); conductor and embolus almost covering the whole genital bulb in ventral view ( Figs 19 B, 21A).

Female (paratype): Total length 2.12. Cephalothorax 0.93 long, 0.80 wide. Abdomen 1.38 long, 1.05 wide. General appearance as in male. Leg measurements: I 4.98 (1.41, 1.61, 1.29, 0.67), II 3.76 (1.10, 1.20, 0.95, 0.51), III 2.03 (0.68, 0.66, 0.45, 0.24), IV 2.97 (0.96, 0.95, 0.71, 0.35). Epigynum with larger atrium ( Figs 20 B, 22A); spermatheca membranous, three times longer than wide in dorsal view ( Figs 20 C, 22B); copulatory ducts very close to each other ( Figs 20 C, 22B).

Variation. Males, total length 1.75–2.05 (n=7); females, total length 1.85–2.88 (n=19).

Distribution. China (Yunnan).
