Nigorella orientalis ( Song & Chai, 1992) comb. nov. ( Figs 13A–B View FIGURE 13 , 14A–F View FIGURE 14 )
Pharacocerus orientalis Song & Chai, 1992: 80 , figs 8A–D (♂); Song & Li, 1997: 436, figs 47A–D (♂).
Evarcha orientalis View in CoL : Song et al., 1999: 510, figs 294O, P, 295A, B (♂, ♀ misidentification, transferred from Pharacocerus View in CoL ); Peng, 2020: 138, figs 87a–h (♂, ♀ misidentification).
Type material. Holotype ♂ (IZCAS-Ar9264), China, Hubei Province, Badong County, 19.V.1989, examined.
Diagnosis. This species resembles N. sichuanensis ( Peng, Xie & Kim, 1993) in the bifurcated retrolateral tibial apophysis, but differs by the tegular lobe folded and curved prolaterally (vs. straight and curved retrolaterally in N. sichuanensis ).
Redescription. Male (holotype): Measurements see Song and Chai (1992).
Coloration ( Figs 14A, B View FIGURE 14 ): Carapace brown, yellow-brown medially, black rings around eyes. Clypeus brown with sparse hairs. Fovea longitudinal. Chelicerae, endites, labium and sternum brown. Legs brown with black rings, covered with sparse setae, more obvious in metatarsi and tarsi. Opisthosoma almost oval, dark brown with yellow-brown pattern. Spinnerets black-brown.
Male left palp ( Figs 13A, B View FIGURE 13 ): Patella as long as tibia, tibia longer than wide, retrolateral tibial apophysis bifurcated, ventral branch triangle-shaped, blunt; dorsal branch tip sharp, needle-shaped, almost two times longer than ventral branch. Cymbium flattened, covered with long setae. Tegular almost oval, with sperm duct extending along margin, Tegular lobe curved. Embolus stout, compound terminal apophysis behind embolus, connected to embolus with membrane.
Female. Unknown.
Distribution. China (Hubei, Sichuan, Guizhou).
Comments. The female of Nigorella orientalis comb. nov. described by Yang and Tang (1995) is identical to those of N. sichuanensis ( Peng, Xie & Kim, 1993) , and is actually a misidentification. Peng (2020) included Evarcha sichuanensis (now in Nigorella ) within E. orientalis , but did not propose the synonymy. However, after examining the specimens, we found that they are clearly different in the tegular lobe, and then should be two species.
