Phylogeny of Holophasmatodea, showing the placements of Breviala cretacea and Electroclavella genuina, and the wing characteristic and ancestral states, see Additional file 1: Figs. S2 and S3 for details of the strict consensus tree and ancestral character state reconstruction of wings. The numbers under the branch nodes are bootstrap support values (data in blue). “†” indicate the fossil species
