Fig. 4. Morphology of mesospina in representatives of Ensifera (A���L) and Caelifera (M). (A���D) Volume rendering. (E���M) 3D reconstruction. Orthoptera bear a stalked mesospina (green asterisk).The vast majority of Ensifera is characterized by a mesospina that bears paired dorsolateral* and ventrolateral processi, only Comicus calcaris has a single lateral process (F). Whereas the dorsolateral processus* is tapered in most Ensifera, the dorsolateral process* in Gryllus bimaculatus is knob-like (E). Some taxa have an unpaired posterior process, marked by pink asterisk.The mesospina of Stenobothrus lineatus is characterized by a distal plate that lacks processi. st2 (mesosternum), st3 (metasternum).
