I would call it a kip tail jig. Some tie with just a thread neck collar and the kip tail and some have a chenille body like these and either exposed thread or not. Just kind of depends on what someone likes. I tie the ones I make with no body materials. I do always use Red thread and I don't put flash on my kip tail jigs, but I add a piece/strip of Red Floss coming from the neck to the tail end.
Nice bright colors you have there!
