Otacilia florifera sp. nov. ( 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.

Carapace yellow and black, oval, abruptly narrow anteriorly, medium black; thoracic part slightly higher than the cephalic part; fovea longitudinal, distinct. Diameter of eyes: AME 0.10, ALE 0.08, PME 0.07, PLE 0.08. Eye interdistances: AME–AME 0.05, AME–ALE 0.01, PME–PME 0.07, PME–PLE 0.04. MOA 0.28 long, front 0.26 wide, back 0.25 wide. Clypeus 0.11 high. Chelicerae light brown, with two bristles anteriorly; promargin of cheliceral furrow with three well-separated teeth and retromargin with five teeth near to each other.

Femora I–IV with only one dorsal spine. Femur I with four prolateral spines and femur II with three prolateral spines; tibia I with eight pairs ventral spines, tibia II with seven pairs of ventral spines; metatarsus I with four pairs of ventral spines, metatarsus II with four proventral spines and three retroventral spines. Abdomen dark with white, with several light blackish chevron-like stripes posteriorly.

Palp ( Figs 23–26 , 29–32 ). Femoral apophysis located ventrally. RTA broad, bird-head-shaped. Tegular apophysis small, short, hilt-shaped. Embolus thin and curved, hook-shaped.

Femora I–IV with one dorsal spine. Femur I with four to six prolateral spines and femur II with three prolateral spines; tibia I with seven or night proventral spines and 7 pairs of retroventral spines, tibia II with eight pairs of ventral spines; metatarsus I with six proventral spines and five retroventral spines, metatarsus II with four proventral spines and three retroventral spines. Abdomen white and black. Other characters as in male.

Epigyne ( Figs 27–28 , 33–34 ). Median plate extending not parallelly, vase-like. Copulatory openings small, situated medially on epigynal plate.
