18-Scorpii-4 Fauna: Rodent Hexapods

Although hexapods dominate the macrofauna of this planet, there are a few animals that occupy lower ecological niche strata, and this group is a perfect example. Suspiciously associated with Earth's rodents, this versatile group of animals has been classified under the code name "RZY," for Rodentia-Zygentoma, which can be translated as "rodent-silverfish."
This code name was chosen after the discovery of the first group of this clade. Simply nicknamed "Tailed," these animals are easily recognizable by their elongated, segmented bodies, somewhat reminiscent of a rat or mouse, and especially by the possession of a kind of abdominal antenna (called a segmented telson) that serves as a sensor.
Later, a second group would be discovered, with stranger characteristics and less akin to the "silverfish" code name. Nicknamed "Sting" due to the absence of a segmented telson, replaced by a pointed telson (resembling a wasp's stinger), this group is also distinguished by the length of its first thoracic segment, while retaining similarities with the other RZY group, such as its rodent-like characteristics. Incidentally, the species described here is an arboreal species similar to squirrels, using its four hind legs to cling to branches in order to reach distant fruit.
