Material examined. Holotype: ♂, mixed forest (36°49 ʹ 05 ʺ N, 129°01 ʹ 46 ʺ E, alt. 619 m), Jaesan-myeon, Bonghwa-gun , Gyeongsangbuk-do, 23 July 2010, J. C. Lim GoogleMaps . Paratypes: 1$, same data as holotype; 1♂, mixed forest (36°50 ʹ 37 ʺ N, 129°07 ʹ 01 ʺ E, alt. 712 m), Socheon-myeon, Bonghwa-gun , Gyeongsangbuk-do, 23 July 2010, J. C. Lim GoogleMaps .

Etymology. The specific name is a Latin adjective “ flavus ” (yellow), referring to the carapace color of the type specimens.

Diagnosis. The new species is easily distinguished from its congeneric species by the shape of paracymbial branch and process, lamellar characteristica, embolus and female internal genitalia ( Fig. 16 View Fig E-H, K).
