Etymology. The specific name comes from the combination of prefix “ tetra- ” and the Latin word “ macroseta ”, meaning “four” and “macrosetae” respectively, and refers to the two pairs of strong macrosetae locating on the cymbium; adjective.

Diagnosis. This species can be easily distinguished from other Wolongia species by the combination of the following characters: 1) brown median stripe of abdominal dorsum with wave-shaped margins ( Figs 29 A, 30A); 2) the longest prolateral seta on Metatarsus I and II about as long as or slightly less than the width of Metatarsus I and II respectively ( Figs 2 I, 32C); 3) femur I with several rows of short median macrosetae prolaterally and ventrally ( Figs 29 C, F; 32A–B); 4) cymbium with two pairs of macrosetae ( Figs 29 E, 31C); 5) cymbial base without a denticle retrolaterally; 6) spermatheca membranous, oval in dorsal view ( Figs 30 C, 32E); 7) copulatory ducts approach spermathecae from posterior-mesal angle ( Figs 30 C, 32E); 8) the distance between terminals of fertilization ducts longer than that between copulatory ducts ( Figs 30 C, 32E). This species resembles W. guoi and W. bicruris n. sp. in short macrosetae on femur I ventrally and prolaterally ( Figs 3 C, F; 6A–B; 15C, F; 18A–B; 29C, F; 32A–B), but differs in: 1) cymbium with four macrosetae versus absent in the latters; 2) absence of a pair of inverted “V”-shaped plates in ventral view of atria which is present in W. guoi ( Figs 16 C, 18D); 3) spermatheca membranous versus strongly sclerotized in W. bicruris n. sp. ( Figs 4 D, 6F).

Description. Male (holotype): Total length 2.05. Cephalothorax 1.05 long, 0.85 wide. Abdomen 1.21 long, 0.91 wide. Carapace yellowish brown, with slightly dark margins. AME 0.08, ALE 0.08, PME 0.09, PLE 0.09, AME-AME=AME-ALE (0.05), PME-PME>PME-PLE (0.07>0.06), LMOA 0.22, AWMOA 0.18, PWMOA 0.21. Clypeus 0.12. Chelicerae yellowish brown, with 5 retromarginal teeth ( Figs 1 I, 31D). Labium dark-brown, width 0.25, length 0.15. Coxae brown. Legs yellow-brown. Femur I with one dorsal longer macroseta and several rows of shorter median macrosetae prolaterally and ventrally ( Figs 29 C, F; 32A–B). Leg measurements: I 5.35 (1.59, 1.83, 1.35, 0.58), II 3.93 (1.22, 1.25, 0.97, 0.49), III 2.29 (0.73, 0.70, 0.51, 0.35), IV 3.20 (1.06, 1.05, 0.78, 0.40). Abdomen oval, widest medially. Dorsum silvery-white, with a brown longitudinal median stripe with wave-shaped margined ( Fig. 29 A). Venter brown, with several pairs of white spots. Cymbium with two pairs of strong macrosetae (the pair near cmp longer than the other pair at the top of cba; Figs 29 E, 31C); conductor with long and thin terminal ( Figs 29 B, 31A).

Female (paratype): Total length 2.40. Cephalothorax 0.95 long, 0.80 wide. Abdomen 1.71 long, 1.36 wide. General appearance and patterns as in male, but femur I without rows of short macrosetae prolaterally and ventrally. Leg measurements: I 4.18 (1.10, 1.34, 1.09, 0.65), II 3.20 (0.90, 1.02, 0.80, 0.48), III 1.92 (0.56, 0.58, 0.41, 0.37), IV 2.80 (0.87, 0.89, 0.63, 0.41). Brown median stripe of the dorsal abdomen narrower anteriorly, wider posteriorly ( Fig. 30 A). Epigynum with larger atrium ( Figs 30 B, 32D); spermathecae membranous, suboval in dorsal view ( Figs 30 C, 32E).

Variation. Males, total length 1.78–2.15 (n=7); females, total length 2.13–2.53 (n=42).

Distribution. China (Yunnan).
