Type material.

Holotype ♂(IZCAS-Ar40396), China: Yunnan: Xishuangbanna, Mengla County, Menglun Township, XTBG, Leprosy Village, 21.8932N, 101.2883E, elevation ca 550 m, 21.IX.2017, Zhigang Chen leg. Paratypes 1♂1♀(IZCAS-Ar40397, Ar40398), same data as holotype.

Etymology.

The species is named after Mr. Ye Xu, who helped us greatly with this research; noun (name) in genitive case.

Diagnosis.

Euophrys xuyei sp. nov. can be easily distinguished from other species by the following characters: male palpal tibia slightly longer than RTA in retrolateral view, tapering to a slightly hooded tip; bulb with tegular lobe covering tibia; embolic terminus flat, with small cusps; epigyne with copulatory openings on each side of median septum located posteriorly; copulatory ducts around spermathecae; accessory glands adjacent to copulatory openings.

Description.

Male (Figs 5A-C , 6C, D, F, G ). Total length 3.03. Carapace 1.70 long, 1.21 wide. Abdomen 1.52 long, 0.98 wide. Clypeus 0.06 high. Eye sizes and inter-distances: AME 0.41, ALE 0.26, PLE 0.23, AERW 0.94, PERW 0.86, EFL 0.64. Legs: I 2.92 (0.89 + 1.11 + 0.51 + 0.41), II 2.35 (0.79 + 0.81 + 0.37 + 0.38), III 2.81 (0.92 + 0.88 + 0.61 + 0.40), IV 3.08 (0.92 + 0.98 + 0.72 + 0.46). Carapace dark brown, cephalic part almost square, thoracic part sloping abruptly, with scattered white setae laterally. Fovea longitudinal, bar shaped. Clypeus dark brown. Chelicerae brown, with two promarginal teeth and one retromarginal enlarged tooth. Endites, labium and sternum colored as chelicerae but paler. Sternum slightly longer than wide, covered with dark setae. Legs yellow to black. Abdomen elongated oval, speckled laterally, with several chevrons posteriorly, covered with white setae; venter yellow-brown with spots.

Palp (Fig. 5A-C ): Patella and tibia dark brown, slightly longer than wide, ventral tibial bump stout; RTA slightly shorter than tibia in retrolateral view, tapering to a slightly hooded tip; cymbium dark brown, longer than wide, widest medially, dorsally with a few short, stout spines in the middle; bulb longer than wide, with sperm duct relatively stout, meandering retrolaterally and tapering prolaterally; tegular lobe distinct, covering tibia; embolus with coiled base; embolic terminus flat with small cusps and thin membrane.

Female (Fig. 6A, B, E ). Total length 3.72. Carapace 1.84 long, 1.36 wide. Abdomen 2.02 long, 1.36 wide. Clypeus 0.07 high. Eye sizes and inter-distances: AME 0.47, ALE 0.28, PLE 0.25, AERW 0.82, PERW 0.77, EFL 0.56. Legs: I 3.00 (0.97 + 1.14 + 0.47 + 0.42), II 2.65 (0.90 + 0.92 + 0.44 + 0.39), III 3.20 (1.10 + 1.02 + 0.66 + 0.42), IV 3.69 (1.10 + 1.19 + 0.89 + 0.51). Habitus similar to that of male except paler.

Epigyne (Fig. 6A, B ) slightly wider than long, windows large, separated by median septum; copulatory openings on each side of median septum located posteriorly; copulatory ducts wrap around spermathecae; accessory glands adjacent to copulatory openings; spermathecae spherical; fertilization ducts originating from the median anterior edge of spermathecae, extending almost transversely.

Distribution.

Known only from the type locality in Yunnan, China.
