Total length 3.16, prosoma (Fig. 14 A) yellow-brown with dark grey mottling, elevated in dorsal view, with radial, irregular dark stripes on the surface, length 1.55, width 1.28. Eye diameters: AME 0.11, ALE 0.10, PME 0.09, PLE 0.10; interdistances: AME – AME 0.05, ALE ̄ AME 0.03, PME – PME 0.11, ALE ̄ ALE 0.45, PLE ̄ PME 0.05, PLE ̄ PLE 0.52, ALE ̄ PLE 0.07, AME ̄ PME 0.08. MOA 0.25 long, front width 0.22, back width 0.30. Cervical groove and fovea distinct. Chelicerae yellow-brown, stout, with two strong setae near base in frontal view, abundant hairs along promarginal teeth, three promarginal (first largest, third smallest) and two retromarginal teeth (equal in size). Endites yellowish, longer than wide. Labium slightly wider than long. Sternum longer than wide, yellow-brown, setae sparse. Opisthosoma elliptical in dorsal view (Fig. 14 A), length 1.52, width 0.99, dark brown, with arched stripe close to anal tubercle. Leg femora yellow-brown, other segments yellow, without annulations; measurements: I 7.65 (1.85, 0.61, 2.35, 1.83, 1.01); II 5.87 (1.49, 0.57, 1.65, 1.36, 0.80); III 4.84 (1.32, 0.45, 1.10, 1.25, 0.72); IV 7.82 (2.11, 0.56, 1.91, 2.16, 1.08).

diagnosis
Diagnosis. The male palpal bulb of the new species is similar to O. limushan Fu, Zhang & Zhu, 2010 (Fu et al. 2015: 444, figs 35 ̄ 51), but it can be easily distinguished from all known Otacilia species by the bifurcate RTA (Figs 14 B ̄ E, 15). Female unknown.
distribution
Distribution. Known only from the type locality in Guangxi Zhuang Autonomous Region, China (Fig. 16).
etymology
Etymology. The specific name is taken from the family name of Prof. Changmin Yin, in honour of her great contribution to Chinese arachnology; noun in genitive case.
