Explanation:

The genus name is Alienus as seen in all the species - specific names provided (e.g., Alienus trichopicus). The species names seem to be chosen based on the physical characteristics of the aliens. For example, "hairy" - like features might lead to a name with "hairicus" (Alienus hairicus), presence of horns might be related to a name like Alienus stripicus (where "strip" could be related to the horn - like structures), and so on.

Answer:

Genus: Alienus
Names were chosen based on physical characteristics of the aliens.
