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.
Diagnosis. The male palpal bulb of the new species is similar to O. limushan Fu, Zhang & Zhu, 2010 ( Fu et al. 2015: 444, figs 35̄51), but it can be easily distinguished from all known Otacilia species by the bifurcate RTA ( Figs 14B View FIGURES 14 ̄E, 15). Female unknown.
Description: Male. Habitus as in Fig. 14A View FIGURES 14 . Total length 3.16, prosoma ( Fig. 14A View FIGURES 14 ) 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, ALĒAME 0.03, PME–PME 0.11, ALĒALE 0.45, PLĒPME 0.05, PLĒPLE 0.52, ALĒPLE 0.07, AMĒPME 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. 14A View FIGURES 14 ), 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). Leg spination: Femur I and II with single dorsal spine; Femur I pv1111, II pv111; Tibia I v22222222, II v22222222; Metatarsus I v2222, II pv111, rv1111. Leg formula: 1423. Spinnerets yellow-brown, with abundant setae.
Palp ( Figs 14B View FIGURES 14 ̄E, 15). Femur with ventral apophysis. RTA large, strong, bifurcate. Spermophor sclerotized. Tegular apophysis arising from tegulum in disto-retrolateral position. Embolus relatively short, hook-shaped.
Distribution. Known only from the type locality in Guangxi Zhuang Autonomous Region, China ( Fig. 16 View FIGURE 16 ).
