Type material: Holotype: male, Mt. Limushan (19°10.874′N, 109°45.322′E, alt. 940 m), Qiongzhong County, Hainan Island, China, 5 May 2011, leg. Yuanye Zhou. Paratypes: 3 males, 1 female (IZCAS), same data as holotype.

Etymology. The specific name refers to the type locality; adjective.

Diagnosis. Similar to I. nigricula sp. nov. in male palp, but the compound teminal apophysis is wider in retrolateral view with darkened tip, and can be distinguished by the details of patellar apophysis ( Figs 135, 136 View FIGURES 135 – 138 , 139–142 View FIGURES 139 – 142 ; with thin and point tip in I. nigricula sp. nov., Figs 181, 182 View FIGURES 180 – 183 , 184–187 View FIGURES 184 – 187 ); from other species by the shape of patellar apophysis ( Figs 135 View FIGURES 135 – 138 , 141 View FIGURES 139 – 142 ). Female differs from I. nigricula sp. nov. by the semioval darkened region on epigyne ( Figs 138 View FIGURES 135 – 138 , 143 View FIGURES 143 – 147 ; 182, 188).

Description. Male ( Figs 135, 136 View FIGURES 135 – 138 , 139–142 View FIGURES 139 – 142 , 145 View FIGURES 143 – 147 ): Total length 1.8, PL 0.9, PW 0.8, OL 0.9, OW 0.6. Eye sizes: AME 0.3, ALE 0.17, PME 0.05, PLE 0.15, AER 0.8, PER 0.75, EFL 0.65. Legs: I 1.75 (0.5, 0.3, 0 45, 0.3, 0.2), II 1.55 (0.45, 0.25, 0.3, 0.35, 0.2), III 1.4 (0.4, 0.2, 0.3, 0.25, 0.25), IV 1.95 (0.65, 0.2, 0.5, 0.35, 0.25); formula: 4123.

Dorsal prosoma brown, with dark sides, covered with brown and white setae. Clypeus height 0.2, Clypeus brown, covered with brown setae. Fovea, cervicle and radial grooves unclear. Chelicerae small and yellow, with two promarginal teeth, retromargin with three teeth. Endites, labium and sternum yellow. Leg I with black longitudinal stripes. Metatarsus I with three pairs of ventral spines. Opisthosoma cylindrical, dark brown, with three pair of pale yellow spots; anterior and posterior margins covered with white and brown setae; ventral opisthosoma yellow with black stripes, booklung black. Spinnerets yellow, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 135, 136 View FIGURES 135 – 138 , 139–142 View FIGURES 139 – 142 ): Patellar apophysis wide and thick, extending to the bottom of bulbus. Compound teminal apophysis broad in retrolateral view, with deep groove extengding towards the spiny apex. Embolus long and curved distally, partially obscured by compound teminal apophysis. Seminal duct twisted, with moderately diameter.

Female ( Figs 137, 138 View FIGURES 135 – 138 , 143, 144, 146, 147 View FIGURES 143 – 147 ): Total length 1.9, PL 0.9, PW 0.8, OL 0.9, OW 0.8. Eye sizes: AME 0.25, ALE 0.15, PME 0.03, PLE 0.15, AER 0.8, PER 0.75, EFL 0.6. Legs: I 1.55 (0.45, 0.25, 0.35, 0.3, 0.2), II 1.4 (0.4, 0.2, 0.3, 0.3, 0.2), III 1.4 (0.4, 0.2, 0.3, 0.3, 0.2), IV 2.0 (0.6, 0.25, 0.5, 0.4, 0.25); formula: 4132.

Optisthosoma oval, grayish brown, with three pairs of pale yellow spots, following one triangle spot. Other characters similar to those of male. Epigyne ( Figs 138 View FIGURES 135 – 138 , 143 View FIGURES 143 – 147 ): heavily sclerotized, anterior portion darkened. Vulva ( Figs 137 View FIGURES 135 – 138 , 144 View FIGURES 143 – 147 ): Copulatory ducts membranaceous and coiled, merged at middle of the vulva. Glandular ducts clear and thin, along with copulatory ducts. Spermathecae small and oval, connect to a large ∏-shaped sclerite.

Distribution. The species is known only from the type locality ( Fig. 258 View FIGURE 258 ).
