Type material.

Holotype: ♂, China, Jiangxi Province, Ji’an City, Suichuan county, Nanjiang Town, Xiajiaoling Village, 26°00'39.41"N, 114°01'03.91"E, 979 m, 5 October 2019, leg. Ke-ke Liu et al. Paratypes: 3 ♂, with same data as holotype.

Etymology.

The specific name refers to a famous tea from the type locality, Gougunao, which is planted on the mountainsides of Suichuan County; noun in apposition.

Diagnosis.

The males of the new species resemble those of O. bizhouica sp. nov. in having an ovoid membranous distal tegular apophysis and hook-shaped embolus (Fig. 1C-F), but can be distinguished from it by the sternum with a sharpened end (Fig. 4B) (vs. relatively blunt), the retrolateral tibial apophysis with a submedial apophysis prolaterally (Figs 4E, F, 5C) (vs. with a basal apophysis prolaterally) and the retrolateral tegular apophysis with a slightly curved apex (Figs 4D, E, 5) (vs. straight apex).

Description.

Male (holotype). Habitus as in Fig. 4A, B. Total length 3.49, carapace 1.87 long, 1.44 wide. Eye sizes and interdistances: AME 0.09, ALE 0.09, PME 0.08, PLE 0.09, AME-AME 0.05, AME-ALE 0.03, PME-PME 0.14, PME-PLE 0.07, AME-PME 0.1, AME-PLE 0.18, ALE-ALE 0.26, PLE-PLE 0.41, ALE-PLE 0.13. MOA 0.25 long, frontal width 0.22, posterior width 0.29. Chelicerae (Fig. 4B) with three promarginal (proximal largest, distal smallest) and six retromarginal teeth (distal largest, proximal smallest, others equal in size). Sternum posteriorly pointed. Pedicel 0.10 long. Abdomen (Fig. 4A, B), 1.67 long, 1.00 wide. Leg measurements (Fig. 4A, B): I 6.46 (1.66, 0.57, 2.12, 1.42, 0.69); II 5.07 (1.21, 0.54, 1.59, 1.05, 0.68); III 4.81 (1.25, 0.50, 1.03, 1.29, 0.74); IV 7.74 (2.41, 0.62, 1.71, 2.21, 0.79). Leg spination (Fig. 4A, B): femur I with two dorsal spines, femora II-IV with one dorsal spine each; femora I pv1111, pv111 (right), II pv111; tibiae I v2222222, II v2222222; metatarsi I v2222, II v2222.

Colouration (Fig. 4A, B). Carapace yellow, with radial, irregular dark stripes submarginally and arc-shaped dark stripes around margin. Chelicerae yellow-brown. Endites and labium yellow, mottled. Legs yellow. Abdomen dark brown, with pair of racket-shaped yellowish spots at posterior of dorsal scutum, three light chevron-shaped stripes on sub-medial part, and two yellowish arc-shaped stripes posteriorly; weak dorsal scutum in anterior half; venter with N-shaped marking and pair sloping markings posteriorly.

Palp (Figs 4C-F, 5). Femoral apophysis well-developed, width more than half of femoral length. Patella unmodified. Tibia with large retrolateral apophysis, less than tibial length, apex blunt, bending inwards to base of cymbium, with submedian apophysis prolaterally and basal apophysis retrolaterally. Cymbium width less than half of its length. Bulb broad oval, with U-shaped sperm duct, apophyses absent. Embolus hook-like, thick, with broad triangular base and narrowed groove, apart from retrolateral tegular apophysis and distal tegular apophysis. Retrolateral tegular apophysis clavate, thick, with slightly curved apex, directed anterolaterally, more than basal 2/3 covered by distal tegular apophysis in ventral view. Distal tegular apophysis oval, arising from base of embolus and retrolateral sperm duct.

Female. Unknown.
