Type material. Holotype: ♂ (MHBU-ARA-00023546; DNA Voucher: KYU037), CHINA: Guangxi Province, Nanning City, Wuming District, Mt. Daming , 21 May 2011, leg. Y. Wang.

Etymology. The specific epithet is in honor of Ms. Linjie Gong (Shanghai), a spider lover who has given tremendous help to the first author in collecting specimens.

Diagnosis. It can be distinguished from all congeners by the presence of a sharp and up-pointed embolic apophysis at the retrolateral side of embolus ( Figs 105 , 108, 109 ).

Description. Male (holotype). Habitus as shown in Figs 100–101 . Carapace length 2.41; abdomen length 2.73; measurements of eyes: AME 0.45, ALE 0.28, PME 0.05, PLE 0.20; measurements of legs: I 4.23 (1.19, 0.85, 0.94, 0.75, 0.50), II 3.67 (1.20, 0.71, 0.67, 0.61, 0.48), III 3.85 (1.22, 0.68, 0.71, 0.78, 0.46), IV 4.37 (1.35, 0.68, 0.95, 0.89, 0.50); leg formula 1432. Carapace dark, cephalon covered by relatively dense yellow setae, with yellowish setal band at each lateral side; front edge of clypeus with one row of sparse white setae; dorsal abdomen with four longitudinal narrow yellow setal bands. Melanic areas on legs I–II distinct.

Palp ( Figs 102–104 ): palpal bulb rather swollen, lobe-like protrusion of tegulum short and stout; embolus straight in ventral view, with a prolateral extension at distal half and one sharp embolic apophysis at retrolateral side, surface of embolus rough; apophysis of embolic disc low ( Fig. 109 ); RTA horn-like in retrolateral view; pro-ventral hump of tibia pointing ventrally, obvious in prolateral view ( Fig. 103 ); ventral femoral bump (VFB) relatively high.

Female. Unknown.

Distribution. China (Guangxi).
