( Figs 1–6 ) Type material Holotype female, Gongshan County ( N 27°43’ , E 98°39’ ), Yunnan Province , 2 May 2004 , Zhi­Sheng Zhang and Zi­Zhong Yang leg., ( MHBU ) ; paratypes : 2 males , 3 females , same data as holotype, ( MHBU : one male and three females) and ( DLC : one male) ; 2 females , Pianma ( N 26°01’ , E 98°37’ ), Lushui County , Yunnan Province , 9 May 2004 , Zhi­Sheng Zhang and Zi­Zhong Yang leg., ( DLC ). Etymology The specific name is a patronym in honor of Prof. Ying­Qiu Tang (College of Life Sciences, Lanzhou University), for her help during our study on Chinese spider fauna, name in genitive case. Diagnosis This new species resembles Badumna hirsuta Thorell, 1890 Thorell 1890 : 323 ; Kulczynski 1908; Lehtinen 1967 : 218, fig. 99) and B. insignis (L. Koch, 1872) ( Forster 1970 : 66, figs 144–147; Yaginuma 1967 : 170, figs E–F, sub Ixeuticus robustus ) in the general structure of the epigyne and palpal organ. However, the latter differs from described Badumna species in having the typical keel­like retrolateral ventral tibial apophysis replaced by a small, more medially placed blunt apophysis ( Figs 4–6 ). B. tangae is also characterised by ALE largest, rather than AME, which are smallest or subequal to PME ( Fig. 1 ); epigynal transverse ridge deeply triangular and copulatory ducts coiled into three rings ( Figs 2–3 ); male palpal tibia with a small apico­medially placed retrolateral ventral apophysis. Description Female ( holotype ): Body length 6.03: prosoma 2.70 long, 2.02 wide; opisthosoma 3.51 long, 2.16 wide. Carapace silvery yellow brown, head pale orange with longer brown hairs, thoracic area with radiating dark stripes laterally and shorter brown hairs. Fovea a longitudinal narrow slit. From above, anterior eye row slightly recurved, posterior eye row procurved. All eyes with black rings. Eye diameters: AME 0.11, ALE 0.17, PME 0.13, PLE 0.15. Distances between eyes: AME–AME 0.11, AME–ALE 0.11, PME–PME 0.23, PME–PLE 0.23. MOA 0.40 long, front width 0.33, back width 0.46. Clypeus height 0.11. Chelicerae yellow brown, with three promarginal and two retromarginal teeth, condyle distinct and pale yellow. Labium yellow brown, wider than long (0.55:0.44), and shallowly notched apically and basolaterally. Maxillae yellow brown, 0.82 long, 0.48 wide. Sternum cordate, 1.43 long, 1.16 wide, dark yellow brown, with dark brown long setae only. Legs pale orange, with indistinct black bands, sparse brown hairs and weak spines. Tibiae I with 010/020 ventral spines. Metatarsus I with 4 dorsal trichobothria. Calamistrum occupying about 3/5 length of metatarsus IV. Superior claws of tarsi with 6 teeth, inferior claws without teeth. Leg formula: 1423. Leg measurements:

Palpal tibia with 3 apophyses: a small apico­medially placed retrolateral ventral apophysis, a triangular retrolateral apophysis and a retrodorsal apophysis distally. Median apophysis membranous and spoon­shaped, directed distad in ventral view. Distal conductor and embolus weakly curved. Sperm ducts distinct. Base of tegulum with conspicuous frontal extension. Colouration and general aspects like that of the female holotype . Variations Body length ranges, females 4.95–6.30, males 4.05–5.49. Distribution Known only from the area of Mt. Gaoligong. Biology Webs were found under the barks of pines. Webs were small, irregular, sparse and nearly funnel­shaped. Acknowledgements We thank Dr X. P.
