Figs 10E–F, 15, 16

Type material. Holotype ♂: CHINA: Hubei Province: Enshi Tujia and Miao Autonomous Prefecture, Badong County, Yesan’guan Town, the mountain behind Three Gorges distillery (37°30’44.21”N, 110°19’55.33”E, 1203 m elev.), 24 Mar. 2014, leg. Luyu Wang.

Paratypes: 1♂ 8♀, same data as holotype .

Etymology. The species is named for its similarity to Otacilia komurai (Yaginuma, 1952) .

Diagnosis. This new species resembles O. komurai by having a crescent-shaped embolus and a similarly shaped bulb (see Figs 15C, 16C and fig. 3G in Wang et al. 2012), but the male can be distinguished by the long and clavate shaped TA (vs absent, compare Fig. 16C with fig. 3G in Wang et al. 2012) and the triangular tip of the conductor (vs the round tip, compare Fig. 16B–C with fig. 3F–G in Wang et al. 2012). The female can be distinguished by the short connecting tube (vs long, compare Figs 15E–F, 16E–F with fig. 3H–I in Wang et al. 2012).

Eye sizes and interdistances: AME 0.10, ALE 0.10, PME 0.08, PLE 0.10; AME–AME 0.04, AME–ALE 0.01, ALE–ALE 0.23, PME–PME 0.12, PME–PLE 0.06, PLE–PLE 0.39, ALE–PLE 0.08. Eye area 0.51 wide (EAW), cephalic region 0.71 wide (CRW), EAW/CRW 0.72. CRW/CW 0.55. MOA 0.23 long, anterior width 0.23, posterior width 0.30. Clypeal height 0.13 (CH), CH /AME 1.30. Chelicerae with three promarginal and five retromarginal teeth. Carapace yellow, with broad longitudinal gray band, slightly broader than eye area. Abdomen oval, gray, with small dorsal scutum anteriorly, two triangular black spots alongside scutum, and four black chevron stripes posteriorly (Fig. 10E).

Palp as in Figs 15A–D, 16A–D. FA strongly raised, located at middle part. RTA moderate in length and flakeshaped, strongly curved towards cymbium, with blunt tip, several short setae at base (Fig. 15B–D) and small basal apophysis retrolaterally in dorsal view (Fig. 16D). Tegulum diamond-shaped. TA thin and long, tip curved towards cymbium (Fig. 16C). Sperm duct tapering to embolus. Embolus hook-shaped, with wide base. Conductor thick, tip triangular, about half length of embolus.

Female: total length 3.41–4.18 (n=8). One paratype (Fig. 10F) total length 4.18, carapace 1.63 long, 1.42 wide (CW); abdomen 2.55 long, 1.72 wide. Eye sizes and interdistances: AME 0.10, ALE 0.10, PME 0.09, PLE 0.10; AME – AME 0.04, AME – ALE 0.01, ALE – ALE 0.23, PME – PME 0.10, PME – PLE 0.05, PLE – PLE 0.37, ALE – PLE 0.07. Eye area 0.51 wide (EAW), cephalic region 0.72 wide (CRW), EAW/CRW 0.71. CRW/CW 0.51. MOA 0.23 long, anterior width 0.22, posterior width 0.28. Other characters as for male, except lack of dorsal scutum, heavier color and slightly larger body size (Fig. 10F) .

Epigyne as in Figs 15E–F, 16E–F. Epigynal plate with pair of shallow depressions at middle part. Median septum long (Fig. 15E). Copulatory openings located at middle of depressions, separated by about 1.5 times spermatheca diameter. Bursa oval, large. Copulatory ducts short and thick. Connecting tube longer than CD, strongly curved. Spermathecae small, oval, close to each other.
