Diagnosis
Stertinius donglinsiensis sp. nov. can be distinguished from any congeners by having a swollen bulb, dorsally incrassated male palpal tibia, and a longitudinally extended anterior chamber of spermatheca, which is more than two times as long as the posterior chamber (Figs 42, 43A–B), whereas flat bulb, not incrassated male palpal tibia, and a smaller anterior chamber of spermatheca less than two times as long as the posterior chamber in other congeners (Metzner 2023).
Etymology
The species name is derived from the name of the type locality, Donglinsi Park; adjective.

Legs: I 2.47 (0.73, 0.50, 0.58, 0.37, 0.29), II 1.86 (0.59, 0.33, 0.40, 0.27, 0.27), III 1.72 (0.51, 0.28, 0.35, 0.29, 0.29), IV 2.08 (0.71, 0.33, 0.43, 0.34, 0.27).
HABITUS. Carapace red-brown, almost square, covered with dense yellow and white thin setae, with pair of indistinct dark patches medially on eye field (Fig. 43C, F). Chelicerae yellow-red, with two retromarginal teeth and one pillar-shaped, bifurcated retromarginal tooth (Fig. 43G). Legs I with slightly inflated femora and tibiae, covered with brown long setae ventrally on tibiae (Fig. 43H). Abdomen oval, dorsum lustrous, with irregular median dark patch and lateral yellow stripes, covered entirely by big scutum and sparse white scale-like setae; venter dark brown (Fig. 43C–D).
PALP. Tibia incrassated dorsally, with short, curved retrolateral apophysis blunt apically; cymbium longer than wide, with lamellar, sub-triangular baso-retrolateral apophysis; bulb swollen, with sperm duct extended along margin; embolus short, slightly curved, originates from apical edge of bulb and tapered to pointed tip (Fig. 42).
