Phylogenetic relationships of orthopteroid insects. Within Ensifera, the relationships are currently not resolved. In the phylogeny, sensory organs are summarized for the respective groups. Groups that lack tympanal organs in the tibia are set in grey, mainly tympanate groups are set in black (though cases of secondary reduction occur, the majority of species has tympanal organs). CA, crista acustica; CAH, crista acustica homologue; DO, distal organ; IO, intermediate organ; TO, tympanal organ. Phylogeny adapted from Grimaldi & Engel [90].
