Are you saying there is a situation where a species has no fertile males?
There are many (esp. insects) with infrequent fertile males. I would not be surprised if there were instances where the fertile males had not yet been observed, but I can’t think offhand of a diploid species definitively shown to have none, ever.
modification of previous response:
assuming species with at least the potential for two sexes, as opposed to breeding strains, etc.
