> True, they are of a single mitotype (maternal line), but hardly means that they are clones. 

Haploid males are produced from unfertilized eggs, therefore they have no father. The eggs' genetic material, however, is the product of the recombination of the DNA of the mother's parents. Since genetic crossover occurs at different sites each time an egg is formed, there are no two exactly alike. 

This is partly why siblings from the same parents differ. The DNA of a haploid male is the combination of its grandparents DNA. Also, when DNA is copied errors are made and hence, the possibility of advantageous mutations. But no, they aren't clones.
