Material examined.

Holotype ♂ ( HNU, Lept- Leptoneta -0001-001 ): China, Hunan Province, Lingxian County , 5.XII.1982, leg. Jiafu Wang (information on the label of the type) [Lingxian is an old place name and now belongs to Hengyang City.

Diagnosis.

Male is similar to that of Leptoneta huanglongensis Chen et al., 1982 in having a long tibial apophysis (TA) of palp, but differs by the detailed characters of TA (claviform, gradually more transparent from the base to the tip, with a small spine on its tip in this species vs finger-shaped and bifurcate distally in L. huanglongensis ) (compare Figs 1B, C, E View Figure 1 , 2B View Figure 2 , 3A, B View Figure 3 with Chen et al. 1982: fig. 3).

Description.

Holotype Male. Body (Fig. 1A View Figure 1 ) length 2.20, carapace 0.85 long, 0.70 wide, abdomen 1.35 long, 0.75 wide (data from original description by Yin et al. 1984: 366). Carapace brown. Six eyes, ALE and PLE connected to each other by their black bases, PME separated from ALE and PLE. Thoracic median groove deep brown, needle-shaped. Cervical grooves and radial furrows deep brown, indistinct. Chelicerae yellowish brown, with ten promarginal (teeth gradually becoming smaller and denser from distal end to base of chelicera) and five retromarginal teeth (Fig. 3C View Figure 3 ). Endites deep brown. Labium deep brown, fused to sternum. Sternum deep brown, peltate. Legs deep yellow; measurements: I 8.20 (2.15, 0.30, 2.50, 2.00, 1.25); II 5.40 (1.50, 0.25, 1.60, 1.30, 0.75); III 4.35 (1.25, 0.25, 1.20, 1.10, 0.55); IV 6.60 (1.75, 0.25, 2.10, 1.60, 0.90) (data from original description by Yin et al. 1984: 367). Abdomen brown, ovoid, with wide, horizontal wave stripes (Fig. 1A View Figure 1 ).

Male palp as illustrated in Figs 1B-E View Figure 1 , 2A, B View Figure 2 , 3A, B View Figure 3 . Femur with 10 ventral spines and five dorsal spines (Fig. 3A View Figure 3 ). Patella with several irregularly arranged setae besides distinct dorsal spine (Fig. 1D, E View Figure 1 ). Tibia with two trichobothria dorsally (Fig. 3A View Figure 3 ), with distal special apophysis (TA) and distal spine retrolaterally. TA clavate, gradually more transparent from base to tip, with small spine on its tip (Fig. 2B View Figure 2 ). Tarsus slightly sunken and contracted at middle position, with one distal long spine, three long dorsal spines, two long retrolateral, and two long prolateral spines on distal half, and one long dorsal spine on basal half (Figs 1D, E View Figure 1 , 2A, B View Figure 2 ). Palpal bulb oval, with smooth surface. Conductor membranous, long, upright. Embolus smooth and small, similar color as conductor. Median apophysis needle-shaped, starting at anterior margin of palpal bulb prolaterally (Figs 1B View Figure 1 , 3B View Figure 3 ). Prolateral lobe (PL) medium-sized, elliptical (Figs 1D View Figure 1 , 2A View Figure 2 ). Cymbium not branched distally (Figs 1A-C View Figure 1 , 2A, B View Figure 2 , 3A View Figure 3 ).

Female. Unknown.

Distribution.

Only known from the type locality, Hunan, China (Fig. 9 View Figure 9 ).

Remarks.

According to Platnick (1986, 2007) and Le Peru (2011), all Leptoneta species are limited to the western Mediterranean region and all those from outside the Mediterranean region are probably misplaced. Also, as stated by Tong and Li (2008), the Chinese Leptoneta species should probably be included in one or more new genera. The original designation of Leptoneta monodactyla Yin et al., 1984 is retained in this work pending comprehensive revisionary work.
