Patrons of the Hoon. Uplifted around 533 000 years ago. Originally four-legged herbivores. After Uplift they have a straightened posture, but still only average 1,5 meter tall. Their skin is a fine-grain leather with a greenish-grey tone. The dust-gills below their eyeflaps are usually a bright red. Feeding cilia are gold to lime green.

Even more obsessive than their Hoon clients they have become vital "bean counters" in Galactic society. Many Guthatsa are senior members of the Institute for Navigation and Trade and the Institute of Foresight.
