( Figs 21–34 ) Material examined. Holotype ♂ , China , Hainan Province , Lingshui County , Mt. Diaoluo ( 18°40′13″N , 109°53′44″E ), 28 January 2015 , Li-Na Fu leg. Paratypes : 2♂ , 14♀ , same data as holotype; 8♂ , 28♀ , Wuzhishan City , Mt. Wuzhi ( 18°51′59″N , 109°40′46″E ), 26 January 2015 , Li-Na Fu , Chi Jin leg. Etymology. The specific name derived from Latin word ‘ florifer ’, refers to the abdomen dorsum having some white flowery markings; adjective. Diagnosis. The new species resembles O. jianfengling , both having a similar RTA , but can be distinguished from the latter by: 1) smaller and shorter tegular apophysis; 2) smaller copulatory openings; 3) narrower median plate. The female of this new species also resembles O. limushan in having similar bursae, but can be separated from the latter by the smaller copulatory openings and narrower median plate. Description.
