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 ).
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.
