Insula hebetata sp. nov.

Figs 122–134 , 258

Type material: Holotype: male, Mt. Wuzhishan (18°54.418′N, 109°40.647′E, alt. 941 m), Hainan Island, China, 30 April 2011, leg. Yuanye Zhou. Paratypes: 2 males, 3 females (IZCAS), same data as holotype.

Etymology. The specific name is from Latin hebetatus (blunt), in reference to the shape of male compound teminal apophysis; adjective.

Diagnosis. Male differs from I. scutata sp. nov. in having a shorter patellar apophysis, and the relatively large proximal apophysis on patella connecting to the long apophysis ( Figs 122 , 126–128 ; smaller and hook-liked in I. scutata sp. nov., Figs 206 , 210–212 ); can be distinguished from other species by the shape of patellar apophysis ( Figs 122 , 128 ). Female differs from I. scutata sp. nov. in having arched epigyne ( Figs 124 , 130 ; rectangular in I. scutata sp. nov., Figs 208 , 214 ); can be distinguished from others by the shape and sclerotized extent of epigyne ( Figs 124 , 130 ).

Description. Male ( Figs 122, 123 , 126–129 , 132 ): Total length 2.0, PL 1.0, PW 0.8, OL 1.0, OW 0.75. Eye sizes: AME 0.3, ALE 0.16, PME 0.05, PLE 0.15, AER 0.8, PER 0.75, EFL 0.6. Legs: I 1.8 (0.6, 0.3, 0.4, 0.3, 0.2), II 1.65 (0.5, 0.25, 0.35, 0.3, 0.25), III 1.55 (0.5, 0.25, 0.3, 0.3, 0.2), IV 2.2 (0.7, 0.3, 0.55, 0.4, 0.25); formula: 4123.

Dorsal prosoma light brown, with dark sides, covered with brown and white setae. Clypeus height 0.2, Clypeus gray brown, covered with white setae. Fovea, cervicle and radial grooves unclear. Chelicerae small and yellow, with two promarginal teeth, retromargin with four teeth. Endites, labium and sternum yellow. Leg I with longitudinal stripes. Metatarsus I with three pairs of ventral spines. Opisthosoma cylindrical, yellowish brown, with one pair of pale yellow spots, following three latitudinal stripes; anterior and posterior margins covered with white and brown setae; ventral opisthosoma light brown. Spinnerets light yellow, anterior spinnerets shorter and stronger than posterior ones. Palp ( Figs 122, 123 , 126–129 ): Patellar apophysis long, with small apophysis at 1/4 length distally, and triangular apophysis proximally. Compound teminal apophysis rough and blunt distally, with deep groove at tip of bulbus. Embolus slender and curved. Seminal duct thin and twisted.

Female ( Figs 124, 125 , 130, 131, 133, 134 ): Total length 2.1, PL 1.0, PW 0.8, OL 1.1, OW 0.9. Eye sizes: AME 0.3, ALE 0.16, PME 0.03, PLE 0.15, AER 0.8, PER 0.8, EFL 0.6. Legs: I 1.75 (0.55, 0.25, 0.4, 0.35, 0.2), II 1.5 (0.45, 0.22, 0.28, 0.3, 0.25), III 1.55 (0.45, 0.2, 0.3, 0.35, 0.25), IV 2.3 (0.7, 0.25, 0.6, 0.45, 0.3); formula: 4132.

Opisthosoma cylindrical, yellowish brown, with three black latitudinal stripes. Other characters similar to those of male. Epigyne ( Figs 124 , 130 ): heavily sclerotized, longer than wider, shield-shaped and darkened at median area. Vulva ( Figs 125 , 131 ): Copulatory ducts membranaceous and relatively short, separated at the bottom of vulva. Glandular ducts thin, merged with copulatory ducts. Spermathecae oblong, connect to an irregular sclerite.

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