Unexpected bonus wildlife from the concept art team. Four legs plus two wings means it’s from heptilicus family on the Inner Worlds (Subahu and Maricha). Since it turned up in the Lunar Worlds wildlife guide, that means this clever rascal has mastered inter-solar flight, or (more likely) some jackass rocket crew was smuggling them for the nobility caste, ran into a customs patrol, and had to dump cargo. Now they’re everywhere.
