Type material: Holotype: male, Mt. Yinggezui (19°03.037′N, 109°44.899′E, alt. 622 m), Qiongzhong County, Hainan Island, China, 7 May 2011, leg. Yuanye Zhou. Paratypes: 3 males, 7 females (IZCAS), same data as holotype.

Etymology. The specific name is from Latin scutatus (shield-shaped), in reference to the shape of female epigyne; adjective.

Diagnosis. Male is similar to I. hebetata sp. nov. in the ventral view of male palp, but can be distinguished from the separated proximal apophysis of patella ( Figs 207 View FIGURES 206 – 209 , 211 View FIGURES 210 – 213 ; large and merged with a longer apophysis in I. hebetata sp. nov., Figs 123 View FIGURES 122 – 125 , 127 View FIGURES 126 – 129 ), and the distal portion of compound teminal apophysis ( Figs 213 View FIGURES 210 – 213 ; 129); from others by the relatively long patellar apophysis ( Figs 206 View FIGURES 206 – 209 , 212 View FIGURES 210 – 213 ). Female can be distinguished by the shape of epigyne which with cruciform darkened region ( Figs 208 View FIGURES 206 – 209 , 214 View FIGURES 214 – 218 ).

Description. Male ( Figs 206, 207 View FIGURES 206 – 209 , 210–213 View FIGURES 210 – 213 , 216 View FIGURES 214 – 218 ): Total length 2.1, PL 1.1, PW 0.9, OL 1.0, OW 0.7. Eye sizes: AME 0.3, ALE 0.2, PME 0.04, PLE 0.15, AER 0.9, PER 0.8, EFL 0.75. Legs: I 1.9 (0.6, 0.3, 0.45, 0.3, 0.25), II 1.65 (0.5, 0.3, 0.35, 0.3, 0.2), III 1.6 (0.45, 0.25, 0.3, 0.35, 0.25), IV 2.35 (0.75, 0.3, 0.6, 0.45, 0.25); formula: 4123.

Dorsal prosoma brown, with dark sides, covered with brown and white setae. Clypeus height 0.1, Clypeus gray brown, covered with brown setae. Fovea, cervicle and radial grooves unclear. Chelicerae small and yellow, with one 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. Opisthosoma cylindrical, dark brown, with two pairs of yellow spots; anterior and posterior margins covered with long white and brown setae; ventral opisthosoma yellow. Spinnerets light yellow, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 206, 207 View FIGURES 206 – 209 , 210–213 View FIGURES 210 – 213 ): Patellar apophysis very long, reach tip of cymbium, with small apophysis at 1/5 length distally, and separated hornlike apophysis proximally. Compound teminal apophysis dark, scaly and blunt distally, with notch at tip of bulbus. Embolus slender, partially obscured by tegulum and compound teminal apophysis. Seminal duct thin and twisted.

Female ( Figs 208, 209 View FIGURES 206 – 209 , 214, 215, 217, 218 View FIGURES 214 – 218 ): Total length 2.3, PL 1.1, PW 0.9, OL 1.2, OW 1.1. Eye sizes: AME 0.3, ALE 0.15, PME 0.03, PLE 0.17, AER 0.9, PER 0.9, EFL 0.7. Legs: I 2.0 (0.6, 0.3, 0.45, 0.4, 0.25), II 1.65 (0.5, 0.25, 0.35, 0.3, 0.25), III 1.7 (0.5, 0.25, 0.35, 0.35, 0.25), IV 2.5 (0.75, 0.3, 0.7, 0.45, 0.3); formula: 4132.

Opisthosoma oval, yellowish brown, with three latitudinal stripes. Other characters similar to those of male. Epigyne ( Figs 208 View FIGURES 206 – 209 , 214 View FIGURES 214 – 218 ): heavily sclerotized, shield-shaped and darkened at median area. Vulva ( Figs 209 View FIGURES 206 – 209 , 215 View FIGURES 214 – 218 ): Copulatory ducts wide and partially sclerotized, merged medially. Glandular ducts thin, along with copulatory ducts. Spermathecae oblong, connect to a sheet sclerite.

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