Paratypes 1♂ (IZCAS-Ar42940), Menglun Township, 55 km from Xishuangbanna National Nature Reserve, artificial Ficus microcarpa forest (21°54.97'N, 100°16.05'E, ca 610 m alt.), 21.viii.2011, Q. Zhao leg.; 1♀ (IZCAS-Ar42941), 55 km from Xishuangbanna National Nature Reserve, seasonal rainforest (21°57.70'N, 101°12.52'E, 670 ± 30 m alt.), Q. Zhao and Z. Chen leg.; 1♀ (IZCAS-Ar42942), Mengyang Township, seasonal rainforest off Baihuashan tunnel (22°09.53'N, 101°55.21'E, 860 ± 12 m alt.), 16. xii.2012, Q. Zhao and Z. Chen leg.

Etymology.

The species name is a patronym in honor of Ms Junxia Zhang, who has contributed greatly to the taxonomy of jumping spiders worldwide; noun (name) in genitive case.

Diagnosis.

Laufeia zhangae sp. nov. closely resembles L. aenea Simon, 1889 from China, Korea, and Japan in general habitus and copulatory organs, but it can be easily distinguished by the following: 1) embolus lacks a branched projection (Fig. 12C ) versus branched projection present in L. aenea ( Ikeda 1998: fig. 6); 2) tibia with a subtriangular ventral apophysis (Fig. 12C ) versus ventral apophysis indistinct in L. aenea ( Ikeda 1998: fig. 6); 3) copulatory openings slit-like (Fig. 13A ) versus openings oval in L. aenea ( Ikeda 1998: fig. 7); 4) copulatory ducts with proximal conical accessory glands (Fig. 13B ) versus glands indistinct in L. aenea ( Ikeda 1998: fig. 8).

Eye sizes and inter-distances: AME 0.36, ALE 0.25, PLE 0.22, AERW 1.18, PERW 0.88, EFL 0.78. Legs: I 3.61 (1.13, 1.50, 0.58, 0.40), II 2.96 (0.90, 1.13, 0.53, 0.40), III 2.96 (0.95, 1.08, 0.53, 0.40), IV 3.01 (0.90, 1.13, 0.58, 0.40). Carapace squarish, red-brown to dark brown, covered with dense, white setae, and golden setae on anterior eye bases and clypeus. Fovea dark, longitudinal. Chelicerae dark red to dark, with two promarginal teeth and one retromarginal fissidental tooth with two cusps. Endites red-brown to dark, broadened distally, bearing dense, dark setae at ental margins. Labium dark, almost linguiform. Sternum yellow, covered with pale, thin setae. Legs pale yellow to dark brown. Abdomen suboval, with large, irregular, dark brown patch and two pairs of muscle depressions, covered with short, white, thin setae; venter brown to dark brown, dotted laterally, with pair of dotted lines medially.

Palp (Fig. 12A-D ): tibia short, about 1.5 times wider than long in retrolateral view, with strongly sclerotized, subtriangular ventral apophysis pointed apically, and tapered retrolateral apophysis slightly curved, extending antero-prolaterally to a blunt tip in retrolateral view; cymbium about 1.7 times longer than wide in ventral view, with sparse, long, white scales at dorsum of proximal portion; bulb longer than wide, with subtrapezoid posterior lobe; embolus strongly sclerotized, short, curved towards retrolateral side distally, with a pointed tip directed towards about 1:00 position, and a tapered, blunt basal tooth.

Female (Fig. 13A, B, E ). Total length 3.15. Carapace 1.67 long, 1.26 wide. Abdomen 1.64 long, 1.13 wide. Clypeus 0.03 high. Eye sizes and inter-distances: AME 0.33, ALE 0.23, PLE 0.19, AERW 1.05, PERW 0.87, EFL 0.69. Legs: I 2.66 (0.83, 1.20, 0.38, 0.25), II 2.36 (0.78, 0.95, 0.38, 0.25), III 2.60 (0.85, 0.95, 0.50, 0.30), IV 2.89 (0.88, 1.10, 0.58, 0.33). Habitus similar to that of male except paler.

Epigyne (Fig. 13A, B ): wider than long, with pair of shallow hoods anteriorly; copulatory openings anteriorly located, slit-like; copulatory ducts swollen at origin, extending posteriorly to connect with the base of ental sides of posterior chambers of spermathecae, with proximal, conical accessory glands; spermathecae divided into two sub-spherical chambers; fertilization ducts anterior to anterior chamber of spermathecae, extended transversely.

Distribution.

China (Yunnan), Vietnam.
