The genus Hivanua gen. nov. is established for the harmochirine jumping spiders of the Marquesas Islands, formerly placed in Habronattus F.O. Pickard-Cambridge, 1901 and Havaika Prószyński, 2002. The type species, Hivanua tekao sp. nov. is described, and five species described by Berland are re-illustrated and moved into the genus: Hivanua flavipes (Berland, 1933), comb. nov., Hivanua nigrescens (Berland, 1933), comb. nov., Hivanua nigrolineata (Berland, 1933), comb. nov., Hivanua rufescens (Berland, 1934), comb. nov., and Hivanua triangulifera (Berland, 1933), comb. nov. The female epigyne is much like that of Habronattus, Bianor Peckham & Peckham, 1896, and other harmochirines, with a centrally placed coupling pocket and two atria with crescent-shaped edges. The terminal apophysis of the male palp, which is variable throughout the pellenine subgroup of the Harmochirina, is absent in H. rufescens but present in H. tekao sp. nov., in which it is elbowed much as in Habronattus. These Pacific Island harmochirines, like the Havaika of Hawaii, appear to be largely foliage dwellers, unlike most of their continental relatives.
