Type material: Holotype: male, Liuhe Town (18°10.645′N, 109°33.989′E, alt. 5 m), Sanya City, Hainan Island, China, 15 July 2007, leg. Chunxia Wang. Paratypes: 1 male, 2 females (IZCAS), same data as holotype.
Etymology. The specific name is from Latin ramosus (ramose, branchy), in reference to the shape of male patellar apophysis; adjective.
Diagnosis. Male can be distinguished from I. minuta sp. nov. by the erect compound teminal apophysis with a thin apophysis visible in retrolateral view ( Figs 194 View FIGURES 193 – 196 , 198 View FIGURES 197 – 200 ; 168, 172); from other species by the branchy patellar apophysis ( Figs 193, 194 View FIGURES 193 – 196 , 198, 199 View FIGURES 197 – 200 ). Female differs from I. hebetata sp. nov. and I. scutata sp. nov. in having less sclerotized epigyne, which with a notch at anterior margin ( Figs 195 View FIGURES 193 – 196 , 201 View FIGURES 201 – 205 ; 124, 130; 208, 214); can be distinguished from other species by the shape of epigyne which is approximately twice as long as wide ( Figs 195 View FIGURES 193 – 196 , 201 View FIGURES 201 – 205 ).
Description. Male ( Figs 193, 194 View FIGURES 193 – 196 , 197–200 View FIGURES 197 – 200 , 203 View FIGURES 201 – 205 ): Total length 1.7, PL 0.9, PW 0.7, OL 0.8, OW 0.65. Eye sizes: AME 0.2, ALE 0.15, PME 0.03, PLE 0.15, AER 0.7, PER 0.7, EFL 0.5. Legs: I 1.45 (0.45, 0.25, 0.35, 0.25, 0.15), II 1.25 (0.4, 0.25, 0.25, 0.2, 0.15), III 1.3 (0.4, 0.2, 0.25, 0.25, 0.2), IV 1.8 (0.6, 0.25, 0.45, 0.3, 0.2); formula: 4132.
Dorsal prosoma 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 two promarginal teeth, retromargin with three teeth. Endites, labium and sternum yellow. Legs I with black longitudinal stripes. Metatarsus I with three pairs of ventral spines. Optisthosoma cylindrical, yellowish brown, with two pairs of yellow spots, following one yellow latitudinal stripe; anterior and posterior margins covered with long brown setae; ventral opisthosoma yellow. Spinnerets light brown, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 193, 194 View FIGURES 193 – 196 , 197–200 View FIGURES 197 – 200 ): Patellar apophysis wide and long, reaching half of bulbus, with four branches. Compound teminal apophysis bent and smooth, with blunt apex. Embolus long and curved distally.
Female ( Figs 195, 196 View FIGURES 193 – 196 , 201, 202, 204, 205 View FIGURES 201 – 205 ): Total length 1.9, PL 0.9, PW 0.8, OL 1.0, OW 0.9. Eye sizes: AME 0.25, ALE 0.15, PME 0.04, PLE 0.15, AER 0.7, PER 0.75, EFL 0.6. Legs: I 1.5 (0.45, 0.25, 0.35, 0.25, 0.2), II 1.3 (0.4, 0.2, 0.3, 0.25, 0.15), III 1.4 (0.4, 0.2, 0.3, 0.3, 0.2), IV 1.95 (0.6, 0.25, 0.5, 0.35, 0.25); formula: 4132.
Optisthosoma oval, yellowish brown, with two pairs of pale yellow spots, following two yellow latitudinal stripes. Other characters similar to those of male. Epigyne ( Figs 195 View FIGURES 193 – 196 , 201 View FIGURES 201 – 205 ): moderately sclerotized, longer than wider, longitudinal axis darkened. Vulva ( Figs 196 View FIGURES 193 – 196 , 202 View FIGURES 201 – 205 ): complicated, with membranaceous and folded copulatory ducts. Glandular ducts mostly obscured by an irregular sclerite. Spermathecae large and oblong.
