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).

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.

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).
