Type material.

Holotype ♂(IZCAS-Ar40911), China: Yunnan: Xishuangbanna, Mengla County, Menglun Township, XTBG, Leprosy Village, 21.8932N, 101.2883E, elevation ca 550 m, 20.IX.2017, Yanfeng Tong leg. Paratypes 4♂1♀(IZCAS-Ar40912-Ar40916), same data as holotype.

Etymology.

The specific name is a noun in apposition and refers to the type locality.

Diagnosis.

Nigorella mengla sp. nov. resembles N. sichuanensis Peng, Xie & Kim, 1993 and Evarcha orientalis (Song & Chai, 1992) by the bifurcated RTA and dorsal embolic apophysis behind the embolus but differs in the following: the palpal tibia is wider than long (vs. longer than wide in N. sichuanensis ); the tegular lobe is folded (vs. straight in N. sichuanensis and E. orientalis ). In the female, the spermathecae are S-shaped (vs. spermathecae coiled in N. sichuanensis ), and the hoods are deeper (vs. unobvious in E. orientalis ).
