Etymology.
The specific name refers to the
type
locality; noun in apposition.
Diagnosis.
The new species is similar to
O. macrospora
Fu, Zhang & Zhang,
2016
in having a stout embolus and a triangular tegular apophysis in the male palp, and by the relative wider median plate, the depressed area and the short copulatory ducts in the female genitalia. It differs from
O. macrospora
by the relatively longer and stronger RTA in the male palp and by the larger depressed area in the female epigyne (compare
Figs 3B
̄D, 4B, C, 5D, E with figs 22̄
26 in
Fu
et al.
2016a
).
Description:
Male. Habitus as in
Fig. 3A
. Total length 3.07, prosoma yellow-brown (
Fig. 3A
), elevated in dorsal view, with irregular dark grey radial strips and arc-shaped dark strips mediolaterally, length 1.52, width 1.34. Eye diameters: AME 0.08, ALE 0.07, PME 0.08, PLE 0.08; interdistances: AME–AME 0.06, ALĒAME 0.03, PME–PME 0.12, ALĒALE 0.15, PLĒPME 0.27, PLĒPLE 0.19, ALĒPLE 0.07, AMĒPME 0.08. MOA 0.23 long, front width 0.22, back width 0.28. Cervical groove and fovea distinct. Chelicerae yellow-brown, stout, with two strong setae near base in frontal view, abundant hairs around promarginal teeth, three promarginal (proximal largest, distal smallest) and six retromarginal teeth (distal largest, others equal in size). Endites yellowish, longer than wide. Labium as long as wide. Sternum longer than wide, yellowish, setae sparse. Opisthosoma elongate elliptical in dorsal view (
Fig. 3A
), length 1.54, width 0.96, yellow-brown, with pair of small oval and larger triangular yellowish spots medially, pair of triangular yellowish spots anterolaterally, and four narrow chevrons on posterior part; venter yellow, with irregular dark spots near spinnerets; weak dorsal scutum in anterior half, extending slightly past midpoint. Legs yellow, with indistinct annulations on distal part of femora, patellae, tibiae and metatarsi; measurements: I 6.15 (1.68, 0.44, 1.79, 1.44, 0.80); II 5.14 (1.39, 0.45, 1.39, 1.18, 0.73); III 4.16 (1.15, 0.29, 0.98, 1.08, 0.66); IV 7.00 (2.00, 0.51, 1.68, 1.92, 0.89). Leg spination: Femur I and II with one dorsal spine; Femur I pv1111, II pv111; Tibia I v22222222, II v2222222; Metatarsus I
v2222
, II pv111, rv1111. Leg formula: 4123. Spinnerets yellow, with abundant setae.

Palp (
Figs 3B
̄D, 5ĀC). Femur with a ventral apophysis. RTA large, finger-like, with 6̄10 strong setae located at the base in ventral view, and with a blunt tip. Spermophor dark brown, strongly sclerotized, around the membranous conductor. Tegular apophysis clearly visible, near the base of embolus, large, triangular. Embolus relatively long, with a blunt apex.
Female.

MOA 0.23 long, front width 0.22, back width 0.27. Opisthosoma (
Fig. 4A
) length 2.22, width 1.59, with two pairs of oval yellowish spots on anterior part, three inverted V-shaped yellowish chevrons on posterior part, and oval yellowish stripe near anus in dorsal view. Legs (
Fig. 4A
