i was requested to provide an opinion here by comfykem everyone agrees that virus species and genera are inherently different usual practice for a genus with a single species would be to construct a single article to cover both and that's sensible where the pair would otherwise duplicate each other however there's no reason in principle why each can't have an article as long as there is sufficient distinctive reliably sourced material in each to merit that this appears to be the case here just about though bloating the lloviu virus article with speculative information about what the virus particle might look like appears unhelpful if we are to have a single article on a genus with a single species as plantdrew suggests it would probably be best to have it at the species name as that is what the bulk of readers are most likely to search for
