Epigynium: 31 wide, 18 long, basally with granules, distally with about 14 longitudinal ridges, genital setae (3a) 6 long, Gt­Gt 19 apart.

Male: (n=2) Body 146 long, shield 46 long, 55 wide; genitalia 17 wide, 4 long, genital setae 5 long, Gt­Gt 12 apart.

Type data: Holotype, female, NANTOU: Renai Township; 6­Oct.­1994, C. F. Wang; ex. Stauntonia hexaphylla (Thunb.) Decne. (Lardizabalaceae) . (deposited at NMNS). Paratypes, 8 females, 2 males, data same as for holotype.
