Armored scale insects (Hemiptera: Coccoidea: Diaspididae) display a diverse array of genetic systems, life history strategies, and ecological associations amongst 2,000 or so species. We present molecular systematic data particularly pertinent to understanding the evolution of male paternal genome elimination and the role of male-female conflict in the evolution of haplodiploidy in this group. Through broad phylogenetic sampling of the diaspidids, we examine the polarity and frequency of the shift between late and early paternal genome elimination.
