GURPS Aliens in a space campaign

[combatmedic]

I've decided to run a GURPS Space campaign as my first campaign with 4E GURPS. The campaign universe will be built using a combination the all four GURPS SPACE atlases, articles from Pyramid, and some stuff of my own design. The idea is a sort of thinking man's space opera. Not Star Wars or Flash Gordon; more like Humanx ,Terro-Human Future History, or Known Space. The known worlds will occupy a very large region within the Milky Way Galaxy.

I need advice on aliens. I want about nine spacefaring races , maybe less. Not counting minor, planetbound or primiive races. Here's what I have picked out so far:

Humans [ of course]

Treefolk

Sparrials

Pachekki

Irari

Memer & Saret

- All of the aliens on this list are described in GURPS Aliens. I don't have the book, but I will buy it soon [hardcopy, most likely]. I ruled out the following:

anything with psionics [I'm not using psionics]

anything too obviously an anthropomorphic animal, especially if the race seems stereotypical[ hence, the Kaa are definitely out]

anything too much like humans [ no humans with bumpy heads/faces or green skin]

Beyond that, I'm hesitant about including ''all evil'' races.

Any suggestions from the community? Aliens from GURPS Aliens, Pyramid, etc.?
