Figures 4 , 5 , 6 Leptoneta trispinosa Yin et al. 1984 : 364, fig. 1a-f (♂♀); Song 1987: 105, f. 68 (♂♀); Song et al. 1999: 51, figs 20R, 21L-M (♂♀, reproduction of the original figure); Yin et al. 2012 : 157, fig. 27a-f (♂♀). Material examined. Holotype ♂ ( HNU , Lept- Leptonetela -0001-001 ): China , Hunan Province , Changsha City, Mountain Yuelu , 25.V.1982 , Jiafu Wang leg.; paratypes 3♂ 3♀ ( HNU , Lept- Leptonetela -0001-002-007 ), same data as holotype (information on the label of the type) [Mountain Yuelu: 112°58'N, 28°12'E]. Diagnosis. The male of Leptonetela trispinosa ( Yin et al., 1984 ) comb. nov. is similar to those of Leptonetela hangzhouensis ( Chen et al., 1984 ) and Leptonetela microdonta (Xu & Song, 1983) in having the median apophysis fork-shaped and a similar arrangement of spines on the retrolateral palpal tibia (compare Figs 4B , 6D with Wang and Li 2011 : figs 13B, D, 28B, D), but differs from L. hangzhouensis by the shape of the teeth on the median apophysis (the middle two teeth ca half of the lateral two in length in this species vs ca one-third in L. microdonta ) (compare Fig. 4B with Wang and Li 2011 : fig. 13B), and from L. microdonta by the number and shape of teeth on the median apophysis (four teeth, the middle two teeth ca half of the lateral two in length in this species vs five teeth, the middle three teeth very small, shorter than one fourth of the lateral two in L. microdonta ) (compare Figs 4B , 6D with Wang and Li 2011 : figs 28B, D). The female of Leptonetela trispinosa can be distinguished from that of Leptonetela microdonta by the different twisting of the spermathecae (compare Fig. 5E with Wang and Li 2011 : fig. 29C, D). Figure 4. Leptonetela trispinosa ( Yin et al., 1984 ), comb. nov., holotype male A habitus, dorsal view B palpal bulb, ventral view C palp, prolateral view D palp, retrolateral view. Description. Holotype Male. Body (Fig. 4A ) length 1.80, carapace 0.80 long, 0.80 wide, abdomen 1.00 long, 0.73 wide (data from original description by Yin et al. 1984 : 364). Carapace yellow brown (Fig. 4A ). Six eyes, ALE, and PLE connected to each other by the black bases, PME separated from ALE and PLE. Thoracic median groove short, brown, needle-shaped. Cervical grooves and radial furrows brown, indistinct. Chelicerae tawny, with eight promarginal (teeth gradually becoming smaller and denser from the distal end to the base of chelicera) and four small retromarginal teeth (Fig. 6D ). Endites tawny. Labium brown, fused to sternum. Sternum tawny, peltate. Legs yellow; measurements: I 6.80 (2.01, 0.33, 2.33, 0.83, 1.30); II 6.27 (1.70, 0.30, 1.83, 1.43, 1.01); III 5.02 (1.43, 0.23, 1.43, 1.10, 0.83); IV 6.65 (1.93, 0.23, 2.00, 1.39, 1.10) (data from original description by Yin et al. 1984 : 364). Abdomen pale brown, oval, lacking distinct patterns (Fig. 4A ). Male palp as illustrated in Figs 4B-D , 6A-C . Femur without strong spines. Patella with a small spine dorsally. Trichobothria not found on the dorsal tibia, although they are usually present in the other congeneric species; it is very possible that trichobothria have detached from the body and been lost. Tibia with one seta and five spines retrolaterally (three very strong spines in longitudinal row, other two near distal end of tibia obviously shorter and thinner). Tarsus slightly sunken and contracted at middle resulting in formation of earlobe-shaped process distally (Fig. 4D ); one distal spine, one ventral long spine, one long retrolateral spine, and one long prolateral spines present on distal half of tarsus (Figs 4C, D , 6A, B ). Palpal bulb oval, smooth. Conductor lamellar, membranous, and slightly wide. Embolus membranous, broad, with the distal part slightly curled towards base (Fig. 6C ). Median apophysis fork-shaped, with four teeth, lateral two strong and middle two smaller (Figs 4B , 6C ). Prolateral lobe medium-sized, elliptical (Fig. 6A ). Figure 5. Leptonetela trispinosa ( Yin et al., 1984 ), comb. nov., paratype female A carapace, dorsal view B abdomen, dorsal view C habitus, dorsal view D habitus, ventral view E vulva, dorsal view. Abbreviations: At, atrium; SS, spermathecae stalk; SH, spermathecae. Paratype . Female. Similar to male in general features and body size, but coloration paler (Fig. 5A-D ). Body length 2.17, carapace 0.90 long, 0.73 wide, abdomen 1.27 long, 0.87 wide (data from original description by Yin et al. 1984 : 364). Chelicerae tawny, with eight promarginal and five small retromarginal teeth (Fig. 6E, F ). Leg measurements: I 7.08 (2.00, 0.26, 2.13, 1.69, 1.00); II 5.55 (1.60, 0.20, 1.69, 1.26, 0.80); III 4.62 (1.20, 0.20, 1.33, 1.20, 0.69); IV 5.86 (1.73, 0.20, 1.80, 1.26, 0.87) (data from original description by Yin et al. 1984 : 366). Genital area densely covered with long hairs. Atrium subtriangular, much wider than long. Internal genitalia consists of paired spermathecae and sperm ducts. Spermathecae highly twisted, with distal ends separated slightly far from each other, and also more strongly sclerotized than proximal part (Fig. 5E ). Distribution. Only known from the type locality, Hunan, China (Fig. 9 ). Note. Because of the poor quality of the images in all available references to the female of L. hangzhouensis the females of these two species cannot be compared. Figure 6.
