Etymology. The specific name refers to the type locality; noun in apposition.
Diagnosis. Male of this species is very similar to those of Otacilia bawangling Fu, Zhang & Zhu, 2010 (Fu et al. 2010: 645, figs 3ĀF), O. biarclata Fu, He & Zhang, 2015 (Fu et al. 2015: 437, figs 1–20), O. florifera Fu, He & Zhang, 2015 (Fu et al. 2015: 444, figs 21–34), O. jianfengling Fu, Zhang & Zhu, 2010 (Fu et al. 2010: 641, figs 1ĀH, 2A–E) and O. limushan Fu, Zhang & Zhu, 2010 (Fu et al. 2015: 444, figs 35̄51), but differs from all these species by the male palp having a RTA with a thick and strong tip, while females can be distinguished by the elongated bursae located at the strong sclerotized band and the roughly elliptical spermathecae (Figs 11B ̄D, 12C, 13ĀC, E).

Chelicerae yellow, stout, with two strong setae near base in frontal view, abundant hairs along promarginal teeth, three promarginal (proximal largest, distal smallest) and three retromarginal teeth (third largest, others equal in size). Endites yellowish, longer than wide. Labium shorter than wide. Sternum slightly longer than wide, yellowish, setae sparse. Opisthosoma elliptical in dorsal view (Fig. 11A), length 2.03, width 0.94, grey dorsally, with three inverted V-shaped yellowish stripes and two arched stripes on posterior part, oval yellowish stripes in front of the anal tubercle; narrow yellow dorsal scutum in anterior half.

Spinnerets yellow, with abundant setae.
Palp (Figs 11B ̄D, 13ĀC). Femur with ventral apophysis. RTA large, finger-like, with curved and thick apex. Spermophor strongly sclerotized. Tegular apophysis near embolus, showing small triangular tip in ventral view. Embolus relatively short, hook-shaped.

Epigyne (Figs 12B, C, 13D, E) with small copulatory openings hidden behind sclerotized ridges. Bursae elongated, anteromedially located at strong sclerotized band. Copulatory ducts very short, broad, medial. Transparent bursae located anteriorly, large, elongated. Glandular appendages short, located at bands between copulatory ducts and spermathecae. Spermathecae relatively large, roughly elliptical, their posterior part hidden in dorsal view under posterior plate. Fertilization ducts arising sub-apical-medially from spermathecae.
Distribution. Known only from the type locality in Guangxi Zhuang Autonomous Region, China (Fig. 16).
