It's pretty clearly what used to be called "archaic Homo sapiens", which is split today into at least Neanderthals, Denisovans, and "other". The article said they ruled out Denisovan, but didn't say on what basis. Denisovan morphology is not well known; the species/subspecies is defined mainly on a genetic basis. This article only looks at morphology, so all they really can be saying is that this mandible doesn't look just like the one known Denisovan partial mandible.
