The Zenodorus ID is almost certainly correct. I was a bit hasty to suggest Sandalodes.

Jerzy Prószyński Rob Whyte is right, it can be Zenodorus. One species - Zenodorus microphtalmus was already reported from Hawaii. To be sure we would need, however, photos of apalp and internal structure of epigyne.

I would more suspect Zenodorus-Omoedus.

I'm not sure, but this looks like it could be an immature (or possibly adult) female of some sort of Sandalodes. The genus is widespread in Hawaii, but the males are a bit more elongate than your specimen.
