( 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.

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.
