( Fig. 5 A-E)

Materials examined. – Holotype: Female (MHBU-Ar-46), Qiankun (28°37'N 106°16'E), Zihuai Town , Hejiang County, Luzhou City, Sichuan Province, coll. J. X. Zhang, 30 Jul.2003.

Paratype: 1 female ( ZRC •ARA•507), Dagou Natural Reserve (32°367'N 105°13'E), Qingchuan County, Guangyuan City, Sichuan Province, coll. J. X. Zhang, 13 Jul.2003 .

Diagnosis. – This new species resembles Yaginumanis sexdentatus ( Yaginuma, 1967) ( Wanless, 1984a: 153, Fig. 6A- J), but can be distinguished from the latter by: posterior depression of the epigynum with dark surroundings, copulatory openings at the lateral sides of posterior depression, and posterior portion of the spermathecae larger than that of the latter ( Fig. 5D, E ).

Description. – Female. Total length 5.88-7.25. Holotype total length 7.25: cephalothorax 3.06 long, 2.16 wide, 1.62 high; abdomen 4.32 long, 2.70 wide. Carapace ( Fig. 5A ) black brown, eye area darker in color with many white fine hairs and several black long setae, the area behind PLSs earthy yellow. Eye sizes: AME 0.57, ALE 0.30, PME 0.22, PLE 0.29. Anterior eye row 1.80 wide, median row 1.58 wide, posterior row 1.67 wide, eye area 1.43 long, clypeus height 0.13. Chelicerae ( Fig. 5C ) red brown, with a brown patch in the front surface, promargin with 3 teeth and retromargin with 5 teeth. Endites and labium red brown, with distal inner margins of endites and tip of labium white. Sternum yellow, with darker margins. Spination of leg I: metatarsi v 2-2-2; tibiae v 2-2-2, p 0-1-1; patellae p 0-1-0; femora d 0-2-4. Leg measurements: I 5.95 (1.80+2.30+1.17+0.68), II 5.95 (1.85+2.16 +1.22+0.72), III 6.30 (1.80+2.16+1.53+ 0.81), IV 8.15 (2.25+2.75+2.25+0.90). Leg formula: 431=2. Dorsum of abdomen with an indistinct brownish band in the middle of anterior part, lateral sides brown, with some indistinct stripes anteriorly; venter pale yellow, scattered with some brown patches. Epigynum (Fig. D, E) with an oval depression at the back part; copulatory duct short, spermatheca large and bean-shaped.

Etymology. – The specific name is a patronym in honor of F. R. Wanless, who has made great contributions to the study of jumping spiders.
