There is pretty high chance that Nerusukyura is a Carapaceon. 4 Legs and 2 claws(most likely used for bring food to it's web and to hold eggs) plus Arachnid like body,most likely.

I think I have a way we can tell Carapaceons and Neoptreons apart.

Carapaceons:4 Legs(for walking and running),2 Claws(used to capture,hold prey or egg sacs),usually blue or multi-colored blood(red,yellow,green,gray),having soft under-bellys and soft backs usually covered by something,sonic bomb weakness and poor eyesight.

Neoptreons:6 Legs(to walk and land on stuff),hooks or special pads on the feet(to hold on to surfaces like walls or ceilings or food),wings(I believe Altaroth have wings if their a Queen or a King,when they leave the nest),good eyesight and extremely weak to poison.

Carapaceons:Hard shells.

Neoptreons:Fragile Shells.

I know I'm most likely missing alot,but thats all the stuff I could think of for both classes in general.
