The phylogeny of Strepsiptera (Hexapoda) [PDF]

open access: bronzeCladistics, 2005
AbstractPrevious phylogenetic analyses of Strepsiptera have been limited to characters from only males or first instar larvae, and by poor taxonomic sampling. This investigation is the first cladistic analysis to use more than fourfold as many characters as any prior study, and a broader sampling of taxa. The analysis of 189 morphological characters of
