These bug people seem easy enough to adapt to Pathfinder. Use the Pathfinder rules for "small sized" creatures, drop the favorite class and extra power points, and done.
Looked up some of the stuff on d20pfsrd, and liked what I saw (am waiting for the PDF to download at time of typing). The only issue that I have with their dromite write up is how embedded the race is with psionics. I know, I know, it works with the point of the book.
Fortunatly, with the OGL I can take and adapt the mechanics.
