Type material. Holotype ♁, CHINA: Guangxi Zhuang Autonomous Region: Hezhou City, Pinggui district , Guposhan scenic spot (24°37′47.49″N, 111°31′46.89″E, 830 m a.s.l.), 11 May 2021, leg. Yannan Mu. GoogleMaps

Paratypes: 2 ♁ 9 ♀, with same data as holotype GoogleMaps .

Etymology. This species name is a combination of “ octonarius ” and “ macula ”, referring to the eight light markings on the abdominal dorsum; adjective.

Diagnosis. The male of this new species can be recognized by: 1) the strong and upward-extending embolus, 2) the membranous conductor, 3) the retrolateral tibial apophysis with a bifurcated tip, and curved dorsal tibial apophysis extending towards prolateral side of cymbium. The female can be recognized by: 1) the diamond-shaped atrium on the epigynal plate, 2) the widely separated copulatory openings located at the sides of the atrium, and 3) the globular spermathecae that are almost entirely surrounded by the long connecting tubes.

Description. Male (Holotype): total length 2.27, carapace 1.06 long, 0.89 wide; abdomen 1.21 long, 0.84 wide. Eye sizes and interdistances:AME 0.06, ALE 0.08, PME 0.05, PLE 0.06; AME–AME 0.03, AME–ALE 0.01, ALE– ALE 0.15, PME–PME 0.05, PME–PLE 0.04, PLE–PLE 0.23, ALE–PLE 0.03. EAW 0.32, CRW 0.45, EAW/CRW 0.71, CRW/CW 0.51. MOA 0.15 long, anterior width 0.15, posterior width 0.15. CH 0.13, CH /AME 2.17. Labium 0.12 long, 0.17 wide. Sternum 0.61 long, 0.56 wide. Leg measurements: Ⅰ 3.22 (0.88, 0.37, 0.84, 0.78, 0.35), II 2.87 (0.80, 0.36, 0.65, 0.65, 0.41), III 2.56 (0.71, 0.32, 0.49, 0.62, 0.42), IV 3.80 (0.98, 0.36, 0.88, 0.97, 0.61). Spination: femora I–IV d 1, tibia Ⅰ pv 6 rv 5, tibia II pv 5 rv 5, metatarsi Ⅰ–II pv 4 rv 3.

Coloration. Carapace black, fovea round, with several markings resembling flowing water droplets beside fovea. Abdomen black, covered entirely by dorsal scutum, with four pairs of light markings on abdominal dorsum ( Fig. 9A, B View FIGURE 9 ). Legs yellow except black femora; patellae, tibiae and metatarsi I–IV with black annuli ( Fig. 10 View FIGURE 10 ).

Palp as in Figs 11A–D View FIGURE 11 , 13A–C View FIGURE 13 . Femoral apophysis round, protruded near tip of femur. Retroventral tibial apophysis strong, strongly curved, extending towards ventral side, middle parts wider than base and tip bifurcated as U-shaped; dorsal tibial apophysis digitiform, base wide and tip curved towards prolateral side of cymbium. Tegulum as wide as cymbium, diamond-shaped; tegular apophysis triangular, located at retrolateral tip of tegulum. Sperm duct distinct, U-shaped, tapering from retrolateral side of tegulum to embolus. Embolus strong, tip slightly curved, beak-shaped, directed retroventrally. Conductor large, membranous, close to embolus.

Female (One paratype): Total length 2.86, carapace 1.20 long, 1.02 wide; abdomen 1.66 long, 1.37 wide. Eye sizes and interdistances: AME 0.05, ALE 0.08, PME 0.06, PLE 0.07; AME–AME 0.05, AME–ALE 0.01, ALE– ALE 0.17, PME–PME 0.05, PME–PLE 0.04, PLE–PLE 0.24, ALE–PLE 0.04. EAW 0.35, CRW 0.50, EAW/CRW 0.70, CRW/CW 0.49. MOA 0.16 long, anterior width 0.16, posterior width 0.16. CH 0.14, CH /AME 2.80. Labium 0.15 long, 0.19 wide. Sternum 0.71 long, 0.64 wide. Leg measurements: Ⅰ 3.65 (0.97, 0.41, 0.99, 0.88, 0.40), II 3.10 (0.82, 0.38, 0.75, 0.74, 0.41), III 2.85 (0.79, 0.38, 0.54, 0.68, 0.46), IV4.05 (1.03, 0.37, 0.98, 1.02, 0.65). Spination: femora I–IV d 1, tibia Ⅰ pv 6 rv 6, tibia II pv 6 rv 5, metatarsi Ⅰ–II pv 4 rv 3. Other characters as for male, except dorsal scutum absent ( Fig. 9C, D View FIGURE 9 ).

Epigyne as in Figs 12A–B View FIGURE 12 , 13D–E View FIGURE 13 . Epigynal plate weakly sclerotized, posterior edge nearly straight. Atrium diamond-shaped. Median septum thin, Y-shaped. Copulatory openings large, horn-shaped, located at lateral margin of atrium. Copulatory ducts short and thick, straight and connected with oval bursa. Glandular appendages absent. Connecting tube long, thinner than copulatory ducts, nearly surrounding entire spermathecae. Bursa oval, at anterior of the plate. Spermathecae globular, slightly separated. Fertilization ducts located anterior margin of spermathecae.
