Not a biologist but IIRC, male ants develop from unfertilized eggs (and are 'haploid'), and the sperm has no role in the production of male ants. Any fertilized egg produces a female ant. This would proably mean that the queen has means to produce two kinds of eggs, which is quite interesting.

Yes, but normally those males are genetic clones of the mother, and couldn’t be a different species.
