Uahuka
Uahuka is a genus of linyphiid spiders with two species that occur only on the Marquesas Islands.
H.W. Levi transferred it to the family Symphytognathidae in 1972, but this was rejected by Brignoli in 1980.
U. spinifrons has only been found on Ua Huka, U. affinis only on Hiva Oa, a larger island about 50 km to the Southeast.
