Figs 1, 2 Type material. Holotype ♂ - CHINA, Yunnan Province, Zhongdian County, northern Zhongdian [ 27°50.119'N , 99°42.426'E , elevation 3285 m], July 23-30, 2000, X. Yu & H. Zhou (IZCAS). Paratypes: same data but Xiaoxueshanyakou [ 27°49.119'N , 99°41.426'E , elevation 3265 m] - 1♂ (IZCAS); same data but Bitahaixi [ 27°48.105'N , 99°40.429'E , elevation 3285 m] - 2♂ (IZCAS). Etymology. The specific name is taken from the Latin adjective "alpinus" , which means "alpine" and refers to the high altitude of the type locality. Diagnosis. The new species is similar to Raveniola chayi sp. n., Raveniola shangrila and Raveniola songi , all also occurring in Yunnan, but differs by the slightly twisted and bent distal portion of the embolus (Figs 1 A-C , 2 A-C , cf. Figs 6 A-C , 7 A-C ). Raveniola alpina sp. n. can be distinguished from the latter species also by the absence of PMS (present in Raveniola songi ). Figure 1. Raveniola alpina sp. n., male holotype. A palp, prolateral view B palp, ventral view C palp, retrolateral view D habitus, dorsal view E leg I, ventral view F leg II, ventral view G habitus, ventral view. Scale bars: 1.0 mm ( A-C ); 2.0 mm ( D-G ). Figure 2. Raveniola alpina sp. n., male holotype. A palp, prolateral view B palp, ventral view C palp, retrolateral view. Scale bar: 0.5 mm. Description. Male (holotype): TL 14.50, CL 5.75, CW 5.25, AL 6.55, AW 4.00. Eye diameters and interdistances: AME 0.17, ALE 0.31, PME 0.13, PLE 0.15, AME-AME 0.19, AME-ALE 0.10, PME-PME 0.55, PME-PLE 0.08. Leg lengths: I: 17.05 (4.90+2.10+4.40+3.50+2.15), II: 16.15 (4.85+1.50+4.30+3.40+2.10), III: 14.50 (4.25+1.70+3.10+3.25+2.20), IV: 18.45 (5.10+2.15+4.55+4.10+2.55). Labium, sternum and maxillae as shown in Fig. 1G. Maxillae with 15-20 cuspules. Prosoma, palps and legs brown. Spinnerets deep grey (Fig. 1D, G). Metatarsus I noticeably curved (Fig. 1E). PMS entirely reduced, apical segment of PLS digitiform (Fig. 1D, G). Palpal tibia long, cylindrical; bulb long, pyriform; embolus gradually tapering to a slender bent point; distal cymbium with three short, stout spines (Figs 1 A-C , 2 A-C ). Female. Unknown. Distribution. China: northern Yunnan.
