(Figs. 98–100)

Daidalotarsonemus seitus Attiah (1970): 191; Smiley, 1972: 94; Lindquist, 1986: 320; Lin & Zhang, 2002: 62.

Diagnosis. Female: Gnathosoma: Palpal length about 1/5 length of gnathosoma. Dorsum: Reticulate ornamentation on prodorsum. Tergite C ornamented with longitudinal depressions. Setae v1, sc2, c1, c2 and h unmodified in shape. Setae v1 shorter than sc2 (~ 27 and ~ 32, respectively). Setae c1 as long as c2 (~ 13). Setae c1 inserted anteriad midlength of tergite C. Setae h slightly longer than c1 and c2 (~ 14). Setae d, e and f leaf-shaped. Setae d and f identical in shape (ensiform), but different in length (~ 51 and ~ 42, respectively) and width (~ 7 and ~ 6, respectively). Setae e unique in shape (lanceolate), shorter than d and f, but longer than h (~ 27). Setae f ~14 distant from each other, on tubercles. Venter: Tegula truncate, slightly arched posteriorly.Apodemes distinct, except prosternal apodeme past half-way to sejugal one. Apodemes 2 fused to prosternal apodeme. Poststernal apodeme bifurcated anteriorly. Legs: sensory cluster of tibiotarsus I complete. Seta tc” of tarsus II slender and serrate. Male & larva: unknown.

All dorsal setae serrate, except for c1 and c2. Setae v1, sc2, c1 and c2 slender; d and f ensiform with two veins; e lanceolate with two veins. All inserted on tubercles, except for h. Distances between dorsal setae: v1–v1 27 (26–28), sc2–sc2 59 (58–60), v1–sc2 33 (33–34), c1–c1 50 (48–52), c2–c2 107 (105–110), c1–c2 36 (33–40), d–d 46 (46–47), f–f 14 (14–15), e–f 13 and h–h 24 (23–25). Setae sc2 inserted anteriorly to sc1.

Idiosoma—venter: setae 1a 7; 2a 13 (12–14); 3a 16 (16–17) near anteromedial margins of apodemes 3; 3b 11 on posterior ends of apodemes 4. Apodeme 1 conspicuous, fused to anterior end of prosternal apodeme. Apodeme 2 long and fused to prosternal apodeme. Prosternal apodeme conspicuous from junction with apodeme 1 to midlength between apodemes 2 and sejugal apodeme. Sejugal apodeme uninterrupted. Apodeme 3 extending diagonally from proximity of base of seta 3a to anterior margin of trochanter III. Apodeme 4 extending diagonally from midlength of poststernal apodeme to base of seta 3b. Poststernal apodeme bifurcated anteriorly. Tegula 14 (14–15) wide and 5 (5–6) long; posterior margin slightly arched. Setae ps 15 (14–16) serrate.
