Figs 17, 18, 19 Type material. Holotype ♂ - CHINA: Sichuan Province, Yajiang County, Yajiang [ 27°50.119'N , 99°42.426'E , elevation 3285 m], 7 June 2001, X. Yu & H. Zhang (IZCAS). Paratypes: same area but Longjiangbian [ 27°49.119'N , 99°41.426'E , elevation 3265 m], 27 May 2009, X. Yu & H. Zhang - 1♀ (IZCAS). Etymology. The specific epithet, a Latinised adjective, refers to the type locality. Diagnosis. Judging from the shape of the bulb and the distal portion of the embolus, this new species is similar to Raveniola shangrila ( Zonstein and Marusik 2012 , figs 33, 41) but can be distinguished by the slightly curved distal portion of the embolus (Figs 17 A-C , 19 A-C ); conspecific females possess uniquely shaped receptacles, with the inner branches curved inward (Figs 18, 19D).

Prosoma, palps and legs brown. Abdomen, including spinnerets, deep grey (Fig. 17D, G). Palpal tibia long, subcylindrical; cymbium apically with five short, stout spines; bulb long and pyriform; embolus gradually tapering to a slender bent tip (Figs 17 A-C , 19 A-C ). Small PMS present, apical segment of PLS digitiform (Fig. 17D, G). Female (paratype): TL 16.50, CL 6.75, CW 5.80, AL 7.25, AW 5.90. Colouration and most somatic characters as in the male.
