These are amazing
I must admit I know nothing about the coleoptera of Hawaii. Did speciation occur on the islands or are these all individual 'imigrants' from neighboring (where?) areas

not immigrants
They're all on Kauai, the oldest remaining large island. They have no obviously close relatives. Long ago some Asian or Oceanian Dorcus/Prosopocoilus relative made it to Kauai.

amazing, and great to see your expertise here!
Amazing beetle, and what a biogeographical curiosity!
Great to have your expertise here, I was just quoting your work on Scarabs of Nebraska in comments this morning:

Hawaiin insects are not included in the main part of the Guide
There is a page specifically for them. BugGuide is North America in the biogeographical sense, not political.

They are now.
Unless Hawaii isn't in the United States, and someone should change the title on every page.

As noted
