Type material: Holotype: male, Mt. Yinggezui (19°03.037′N, 109°44.899′E, alt. 622 m), Qiongzhong County, Hainan Island, China, 8 May 2011, leg. Yuanye Zhou. Paratypes: 2 males, 3 females (IZCAS), same data as holotype.

Etymology. The specific name is from Latin minutus (small), in reference to the size of the species; adjective.

Diagnosis. Male can be distinguished from other species as follow: from I. curva sp. nov. by the compound teminal apophysis which is rough distally ( Figs 167 View FIGURES 167 – 170 , 173 View FIGURES 171 – 174 ; bent and S-shaped in I. curva sp. nov., Figs 105 View FIGURES 105 – 108 , 111 View FIGURES 109 – 112 ); from I. hebetata sp. nov., I. scutata sp. nov. and I. uncinata sp. nov. by the relatively short patellar apophysis ( Figs 167 View FIGURES 167 – 170 , 173 View FIGURES 171 – 174 ; 122, 128; 206, 212; 245, 251); from I. limuensis sp. nov. and I. nigricula sp. nov. by the branched and longer patellar apophysis ( Figs 167, 168 View FIGURES 167 – 170 , 172, 173 View FIGURES 171 – 174 ; 135, 136, 140, 141; 180, 181, 185, 186); from I. ramosa sp. nov. by the rough tip of compound teminal apophysis which is bent downward ( Figs 173, 174 View FIGURES 171 – 174 ; smooth and bent upward in I. ramosa sp. nov., Figs 199, 200 View FIGURES 197 – 200 ); from others by the details of patellar apophysis. Female differs from other species by the shape of epigyne which is approximately darkened on posterior one third portion ( Figs 170 View FIGURES 167 – 170 , 175 View FIGURES 175 – 179 ).

Description. Male ( Figs 167, 168 View FIGURES 167 – 170 , 171–174 View FIGURES 171 – 174 , 177 View FIGURES 175 – 179 ): Total length 1.7, PL 1.0, PW 0.8, OL 0.7, OW 0.6.

Chelicerae small and yellow, with two promarginal teeth, retromargin with five teeth. Endites, labium and sternum yellow. Leg I with black longitudinal stripes. Metatarsus I with three pairs of ventral spines. Optisthosoma cylindrical, dark brown, with three pairs of yellow spots; anterior margin covered with long brown setae; ventral opisthosoma light yellow. Spinnerets light yellow, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 167, 168 View FIGURES 167 – 170 , 171–174 View FIGURES 171 – 174 ): Patellar apophysis wide proximally and pointed distally, with two sharp points. Compound teminal apophysis broad in ventral view, rough and bent distally, with deep groove extending towards the apex. Embolus long and distally curved.

Female ( Figs 169, 170 View FIGURES 167 – 170 , 175, 176, 178, 179 View FIGURES 175 – 179 ): Total length 2.0, PL 0.9, PW 0.8, OL 1.0, OW 0.8. Eye sizes: AME 0.25, ALE 0.15, PME 0.05, PLE 0.15, AER 0.75, PER 0.7, EFL 0.65. Legs: I 1.6 (0.5, 0.25, 0.35, 0.3, 0.2), II 1.35 (0.4, 0.2, 0.3, 0.25, 0.2), III 1.35 (0.35, 0.25, 0.25, 0.3, 0.2), IV 2.05 (0.6, 0.3, 0.5, 0.4, 0.25); formula: 4132.

Optisthosoma oval, grayish brown, with one pair of pale yellow spots, following two yellow latitudinal stripes. Other characters similar to those of male. Epigyne ( Figs 170 View FIGURES 167 – 170 , 175 View FIGURES 175 – 179 ): moderately sclerotized, longitudinal axis darkened, with less sclerotized areas anteriorly. Vulva ( Figs 169 View FIGURES 167 – 170 , 176 View FIGURES 175 – 179 ): Copulatory ducts long and membranaceous, merged at middle of the vulva. Glandular ducts thin and twisted. Spermathecae oval, connect to an irregular sclerite.

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