Males of this species resemble those of A. karschi in the shape of their palpal bulb, but differs in males by metatarsus IV having spines dorsally, by the longer conductor situated far away from tegular process in retrolateral view and with its upper margin almost straight in prolateral view, and by the rounded upper distal corner of the conductor ( Figs 96, 97 ); females differ by the almost equal­sized four pyriform receptacula and the oval lateral patches of pores ( Figs 90–92 ).

Chelicerae red brown, with 13 teeth on promargin and granular texture on pro­ and retrolateral faces. Anterior lobe of pedipalp coxa red brown, inner­margin with row of nine cuspules. Labium and sternum red brown, with black border, 2.79 long and 3.15 wide. Second and third pair of sigilla small. Abdomen oval and dark brown, anterior half with four pale yellow brown cambered bands dorsally, dorsal scutum red brown. ALS 0.40 long, PMS 0.63 long, PLS 2.11 long (basal joint 0.53, median 0.40, subapical 0.50, apical 0.48). Palpal femur with furrow. Legs thin, covered with short and thin hairs and few spines. Legs III, IV, tarsi and metatarsi of legs I, II yellow brown. Femora, patellae and Tibiae of legs I, II red brown. Femur I with granular texture, femur II lacking this texture. Metatarsus IV with five dorsal spines. Leg formula: 4123. TABLE 15. Leg measurements of Atypus suiningensis Zhang 1985 , male.

Male palp ( Figs 95–98 ): conductor longer and far away from tegular process in retrolateral view, upper corner rounded and upper margin almost straight in prolateral view. Female. Total length (including chelicerae) 17.10. Carapace 5.58 long, 5.22 wide; abdomen 7.56 long, 5.13 wide. Carapace similar to that of male in shape, coloration and pattern. Eye tubercle lower in male. Eye region occupying nearly one­third of width of pars cephalica. Eye diameters: AME 0.27, ALE 0.24, PME 0.20, PLE 0.20. Distances AME–AME 0.20, AME–ALE 0.14, PME–PME 0.71, PME–PLE 0.03. MOA 0.55 long, front width 0.71, back width 1.12. Fovea transverse, occupying about 1/10 of carapace width at that point. Chelicerae red brown, with 13 teeth on promargin, lacking granular texture. Anterior lobe of pedipalp coxa similar to that of male, but with more cuspules. Sternum darker than that of male, wider than long. Sigilla as in male. Abdomen oval, dark yellow brown, with small and pale orange dorsal tergite. ALS 0.61 long, PMS 1.16 long, PLS 4.12 long (basal joint 0.75, median 1.02, subapical 1.12, apical 1.05).

Vulva ( Figs 90–92 ): atrium relatively long, with oval lateral patches of pores; all four receptacula pyriform and almost equal in size, lacking obvious basal stalks. Variation. Size range of mature females: carapace length 5.58–5.76, width 5.22–5.40, total length 17.10–17.64, n=25; size range of mature males: carapace length 4.05–4.06, width 3.78–3.96, total length 11.07–12.69, n=4. Habitat. Found abundantly in pursewebs attached to the bases of the China firs and rocks. The total length of tubes of mature females is 27.0–28.0 mm (n = 2), and the aerial portion is 22.5–23.0 mm. Distribution. China : Hunan , Zhejiang . Remarks. This species was originally described by Zhang (1985) from specimens collected in Suining County, Hunan Province , China . Unfortunately he did not provide more valuable characters than vulva structure and narrower conductor. By examining the specimens collected from the type locality, we redescribe this species and provide more relevant illustrations for identification.
