description: <i>Atypus pedicellatus</i> sp. nov. (Figs 56–67) <b>Type material.</b> Holotype male, CHINA: Yunnan Province, Yangbi County, 25°36’N, 99°54’E, Mt Cang, Xueshanhe, 6 May 2001, Z. Z. Yang leg. (MHBU); paratypes: 6 females, same data as for holotype; 1 male and 1 female, same locality as for holotype, 16 May 2001, Z. Z. Yang leg.; 2 females, Yunlong County, 25°54’N, 99°18’E, 28 April 2002, Z. Z. Yang leg.; 19 males, Dali City, Fengyi, 25°30’N, 100°18’E, Mt Gong, 14 June, 2002, Z. Z. Yang leg.; 1 female, Yunnan Province, longchuan County, 24°16’N, 97°54’E, 10 August, 2002, Y. Z. Li leg. (MHBU). <b>Diagnosis.</b> Males of <i>A. pedicellatus</i> closely resemble those of <i>A. suthepicus</i> Schwendinger 1989 in the shape of their palpal organ but differ by the sternum being wider than long and by the oval posterior pair of sigilla (Figs 58, 64); males also possess a relatively longer conductor with a lower upper distal corner, a longer (Fig. 66) and more pointed lower distal corner (Fig. 67); females differ in the larger and almost rounded receptacula, basal stalks of median pair of receptacula being as long as the long diameter of the receptacula, and the pore patches being small and rounded (Figs 59–62). <b>Etymology.</b> The specific name is taken from the adjective Latin “pedicellatus” and refers to the shape of the receptacular stalks. <b>Description.</b> Male (holotype). Total length (including chelicerae) 14.94. Carapace 4.50 long, 4.68 wide; abdomen 5.94 long, 4.05 wide. Carapace with shallow grooves and pits, dark red brown, with dark border and lines. Eye tubercle black. Eye region occupying nearly onethird width of pars cephalica. Both eye rows recurved and almost equal in width. Eye diameters: AME 0.25, ALE 0.25, PME 0.15, PLE 0.18. Distances AME–AME 0.23, AME–ALE 0.07, PME–PME 0.63, PME–PLE 0.00. MOA 0.50 long, front width 0.68, back width 0.90. Fovea transverse, narrow, occupying about 1/10 of carapace width at that point. Chelicerae black brown, with 12 teeth on promargin and granular texture on pro­ and retrolateral faces. Anterior lobe of coxa of pedipalp dark red brown, inner margins with two irregular rows of cuspules. Sternum dark red brown, with black border, 3.15 long and 3.24 wide. Posterior pair of sigilla oval. Abdomen blackish brown, with dorsal scutum red brown. ALS 0.53 long, PMS 0.88 long, PLS 2.65 long (basal joint 0.60, median 0.75, subapical 0.70, apical 0.60 long). Palpal femur with furrow. Legs red brown, patella III, IV, Tibia, metatarsus and tarsus lighter in color. Only femur I with granular texture. Metatarsus IV with five dorsal spines. Leg formula: 4123. Male palp (Figs 65–67): conductor long, its upper distal corner low, lower distal corner long and pointed. Female. Total length (including chelicerae) 19.89. Carapace 5.31 long, 5.31 wide; abdomen 9.45 long, 4.14 wide. Carapace as in male. Eye region occupying nearly onethird of width of pars cephalica. Eyes arrangement as in male. Eye diameters: AME 0.25, ALE 0.28, PME 0.20, PLE 0.20. Distances AME–AME 0.35, AME–ALE 0.15, PME– PME 0.98, PME–PLE 0.00. MOA 0.50 long, front width 0.85, back width 1.28. Fovea transverse, deep and narrow, occupying about 1/10 of carapace width at that point. Chelicerae reddish brown, with 11 teeth on promargin. Anterior lobe of pedipalp coxa reddish brown, with many cuspules on inner margins and inner half of ventral side. Sternum wider than long, with sigilla as in male. Abdomen dark yellow brown, tergite orange. ALS 0.70 long, PMS 1.28 long, PLS 3.86 long (basal joint 0.88, median 1.10, subapical 1.00, apical 0.88 long). Legs yellow brown.
