It's 100% a Carapaceon if you go by logic. Scorpions are arachnids, spiders are arachnids, Scorpion-like monsters are Carapaceons, Spider-like monsters are... yeah, Carapaceons.

Btw the 6 leg theory is completely nonsense as 6 legs are 6 limbs and 2 claws + 4 legs are 6 limbs. So all Carapaceons have 6 limbs as well as the spider-like monster has.

Conclusion: Nelskura is a Carapaceon unless Capcom goes completely crazy.
