Treatment

Leclercera yanjing sp. nov. Figs 30 View Figure 30 , 55L View Figure 55 , 58 View Figure 58

Types.

Holotype: ♀ (IZCAS), China, Tibet Autonomous Region, Shannan, Cona County, Lemenba Ethnic Village, along the road between Lewang Bridge to Zhisimuzha scenic area, 27°49.5710'N, 91°43.7560'E, elevation ca 2793 m, 1.VI.2016, J. Wu leg.

Etymology.

The species name is a noun in apposition derived from the Chinese pinyin “yǎnjìng” (spectacles) and refers to the structure of the spermathecae resembling a pair of spectacles (Fig. 30A View Figure 30 ).

Diagnosis.

Females of L. yanjing sp. nov. can be distinguished from other congeners by a unique curved ‘x’ spot on the external genitalia (Fig. 30B View Figure 30 ) and the spermathecae which resemble a pair of aviator glasses (Fig. 30A View Figure 30 ) (vs. absence of such characteristics in congeners).
