Type material: Holotype: male, Mt. Bawangling (19°04.871′N, 109°07.395′E, alt. 654 m), Hainan Island, China, 27 July 2007, leg. Shuqiang Li. Paratypes: 3males, 1 female (IZCAS), same data as holotype.
Etymology. The specific name is from Latin squamatus (scaly), in reference to the distal shape of male compound teminal apophysis; adjective.
Diagnosis. Male can be distinguished from I. maculata (Peng & Kim, 1997) by the embolus that without apophysis ( Figs 225, 226 View FIGURES 223 – 226 ; bifurcated distally in I. maculata (Peng & Kim, 1997) , Fig. 163 View FIGURES 163 – 166 ); from other species by the scaly compound teminal apophysis, further distinguished by the details of patellar apophysis ( Figs 219 View FIGURES 219 – 222 , 225, 226 View FIGURES 223 – 226 ). Female can be distinguished by the unique shape of epigyne which is relatively large, wider and longer, and sclerotized ( Figs 221 View FIGURES 219 – 222 , 227 View FIGURES 227 – 231 ).
Description. Male ( Figs 219, 220 View FIGURES 219 – 222 , 223–226 View FIGURES 223 – 226 , 229 View FIGURES 227 – 231 ): Total length 1.7, PL 1.0, PW 0.75, OL 0.8, OW 0.6. Eye sizes: AME 0.25, ALE 0.15, PME 0.05, PLE 0.15, AER 0.8, PER 0.7, EFL 0.6. Legs: I 1.65 (0.5, 0.3, 0.35, 0.3, 0.2), II 1.45 (0.45, 0.25, 0.3, 0.25, 0.2), III 1.4 (0.4, 0.2, 0.3, 0.3, 0.2), IV 2.0 (0.65, 0.25, 0.5, 0.35, 0.25); formula: 4123.
Dorsal prosoma light brown, with dark sides, covered with brown and white setae. Clypeus height 0.05, 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, grayish black, with three pairs of pale yellow spots, following one yellow latitudinal stripe; anterior and posterior margins covered with long brown setae; ventral opisthosoma light brown. Spinnerets light brown, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 219, 220 View FIGURES 219 – 222 , 223–226 View FIGURES 223 – 226 ): Patella with several irregular apophyses. Compound teminal apophysis broad and bent, scaly distally, with membranaceous margin and a concave region in retrolateral view, apex obscured by tegulum. Embolus long, extengding under the compound teminal apophysis, and curved distally. Seminal duct visible in prolateral view.
Female ( Figs 221, 222 View FIGURES 219 – 222 , 227, 228, 230, 231 View FIGURES 227 – 231 ): Total length 2.25, PL 1.05, PW 0.85, OL 1.2, OW 1.0. Eye sizes: AME 0.25, ALE 0.15, PME 0.05, PLE 0.15, AER 0.85, PER 0.8, EFL 0.6. Legs: I 1.75 (0.55, 0.25, 0.4, 0.3, 0.25), II 1.55 (0.45, 0.25, 0.3, 0.3, 0.25), III 1.55 (0.4, 0.25, 0.3, 0.35, 0.25), IV 2.2 (0.7, 0.25, 0.55, 0.45, 0.25); formula: 4132.
Opisthosoma oval, yellowish brown, with irregular stripes. Other characters similar to those of male. Epigyne ( Figs 221 View FIGURES 219 – 222 , 227 View FIGURES 227 – 231 ): oblong and heavily sclerotized, with weakly sclerotized region on both sides. Vulva ( Figs 222 View FIGURES 219 – 222 , 228 View FIGURES 227 – 231 ): Copulatory ducts transparent and folded, with wide diameter. Spermathecae small and oval, connect to a sheet sclerite.
