Type material. Holotype: ♀: CHINA: Hunan Province, Chenzhou City, Yizhang County, Mangshan National Forest Park, Linziping Reservoir, 24°57.3'N, 112°56.11'E, 1040 m a.s.l., 6 December 2017, leg. H.Q. Yin, A.L. He, J.X. Liu, Y.H. Xie, Y. Yang and P. Dong.

Etymology. The specific name comes from the Chinese word 'jiandao', meaning 'scissors', referring to the shape of the duct system resembling scissors; noun in apposition.

Diagnosis. The female of this species is similar to Otacilia komurai (Yaginuma, 1952) but differs from the latter by the rounded copulatory openings, the spermathecae near located on the median line of median plate and the sub-semicircular connecting tube (compare Figs 9B, C, 10 with figs 49̄ 52 in Kamura 2009). Male unknown.

Description: Female. Habitus as in Fig. 9A. Total length 4.06, prosoma yellow, elevated in dorsal view, with many radial, irregular, yellow stripes on the surface, broad dark grey marking along midline, lateral margins with dark grey fringe, length 1.60, width 1.53. Eye diameters: AME 0.08, ALE 0.09, PME 0.09, PLE 0.10; interdistances: AME–AME 0.07, ALĒAME 0.03, PME–PME 0.13, ALĒALE 0.28, PLĒPME 0.06, PLĒPLE 0.38, ALĒPLE 0.16, AMĒPME 0.13. MOA 0.27 long, front width 0.23, back width 0.32. Cervical groove and fovea distinct. Chelicerae yellow, stout, with two strong setae near base, abundant hairs along promarginal teeth, three promarginal (proximal largest, distal smallest) and six retromarginal teeth (distal largest, others equal in size). Endites yellow, longer than wide. Labium longer than wide. Sternum longer than wide, yellow, setae sparse. Opisthosoma elliptical in dorsal view (Fig. 9A), length 1.52, width 0.99, dark brown, with arrow-like dark marking in anterior part, four dark chevron-shaped stripes and long arched dark stripe on posterior part; venter yellow, with four irregular dark stripes. Legs yellow, with annulations on distal parts of femora, patellae, tibiae and metatarsi; measurements: I 7.10 (1.86, 0.62, 2.16, 1.79, 0.67); II 5.79 (1.45, 0.57, 1.63, 1.33, 0.81); III 4.15 (1.12, 0.40, 0.51, 1.07, 1.05); IV 7.93 (2.08, 0.60, 1.85, 2.28, 1.12). Leg spination: Femur I pv1111, II pv111; Tibia I v22222222, II v22222222; Metatarsus I v2222, II pv111, rv1111. Leg formula: 4123. Spinnerets yellow-brown, with abundant setae.

Epigyne (Figs 9B, C, 10) with large, rounded copulatory openings located anteriorly, covered with transparent bursae in dorsal view. Bursae large, broadly bean-shaped. Copulatory ducts relatively short and broad. Connecting tube sub-semicircular. Glandular appendages short, located on anterolateral copulatory ducts, between copulatory ducts and connecting tubes. Spermathecae distinct, pear-shaped, near median line of epigyne, partly covered by posterior plate. Fertilization ducts partly covered by spermathecae.

Distribution. Known only from the type locality in Hunan Province, China (Fig. 16).
