Genus Insula gen. nov.

Type species: Insula hebetata sp. nov.

Etymology. The generic name is from Latin insula (island), in reference to the distribution of the genus that only inhabited in Hainan Island. Feminine in gender.

Diagnosis. The jumping spiders of Insula gen. nov. can be distinguished from Salticoida by the presence of a complicated compound terminal apophysis in male palp; from Lyssomaninae , Hisponinae and Spartaeinae by the presence of patellar apophysis in male palp and the merged female copulatory ducts; and from Eupoa and Corusca gen. nov. by the lack of median apophysis in male palp.

Description. Small sized spiders ranging from 1.6 to 2.6 mm in length. Sexes similar in general body form; female light in colour. Prosoma square-built, grayish brown, with dark sides. Opisthosoma cylindrical in male and oval in female, grayish black, with paired yellowish white segments or stripes ( Figs 132, 133 ). Palp with varying patellar apophysis which is species-specific ( Figs 110, 111 ; 127, 128; 172, 173); tibia with two blunt and sheet apophyses. Bulbus without tegular apophysis and median apophysis; compound teminal apophysis originating from the bottom of bulb, extending towards the tip of cymbium, smooth proximally and rough distally, covered most part of embolus; embolus long, extending along the compound teminal apophysis, curved distally; seminal duct slender and twisted ( Figs 122, 123 , 126–129 ). Female epigyne heavily sclerotized, with varying darkened region ( Figs 130 ; 143; 175; 188; 214). Copulatory ducts membranaceous, folded and merged; glandular ducts extending along the merged portion of copulstory ducts; spermathecae oval, connect to a sclerite ( Figs 125 , 131 ; 137, 144; 169, 176; 183, 189; 222, 228).

Twelve species are included in genus Insula gen. nov.: Insula curva sp. nov., I. hebetata sp. nov., I. limuensis sp. nov., I. longa sp. nov., I. maculata (Peng & Kim, 1997) , I. minuta sp. nov., I. nigricula sp. nov., I. ramosa sp. nov., I. scutata sp. nov., I. squamata sp. nov., I. tumida sp. nov. (male and female), I. uncinata sp. nov. And I. maculata (Peng & Kim, 1997) is transferred from Eupoa . All of the specimens were collected from Hainan, Southern China.
