My name suggestions ^_^
Drache'Drache' is German for dragon and this could be a unique idea if you added a bonus fact about where this species originated from and how locals or some sort named these creatures 'Drache'.
Sunēkutēru'Sunekuteru' is a Japanese word that means 'Snake Tail'. I thought this was a cool name because it describes how snake-like they look and how they have different tail variations.
DreigiauAnother word that when translated means 'Dragon'. However this word is Welsh and I think it is very fun to say ^_^
Volare Snake'Volare' means 'flying' in Italian and 'Snake' means...well, 'snake'. I think this is a cool idea because there are two types that have wings even though 1 of them can't fly. But gliding could still give off the appearance of flying and I think 'Volare Snake' could be a fairly catchy name
Miel Perro'Miel Perro' means 'Honey Dog' in Spanish and I got the idea for this name due to you mentioning they can be 'easily treated them like a dog' and that 'their diet consists mostly of fruits and nectar'. I think it is also a fairly cute name <3
Miel, sweet cuddly Perro.
