Havaika
''Havaika'' is a genus of the spider family Salticidae (jumping spiders). The genera ''Habronattus'' and ''Pellenes'' are closely related. All then known species were split from the genus ''Sandalodes'' (subfamily Plexippinae) (, 2002).
All twelve species occur on the islands of the Hawaiian and Marquesas chains. Recent molecular studies suggest that the species from the two chains are the result of independent colonizations (, 2006). The Marquesas species ''H. triangulifera'' and ''H. flavipes'' are not included in ''Havaika'' by , 2008.
Collecting travels in the late 1990 have suggested that the salticid fauna of Hawaii has been drastically exterminated, so it may be that several or most of the described species are in fact already extinct.()
==Description==
Spiders in this genus follow the generalized salticid body plan, but differ from other genera by the appearance of the epigyne. The cephalothorax is dark with variable whitish setae ornamentation on the face and some white and yellow scales on the frontal surface of chelicerae and the rim of the eyes. The body length varies from less than two up to ten mm.〔Proszinski 2008〕
