Fig.3 in Comparative Morphology of the Orthopteran Thorax With a Discussion of Phylogenetically Relevant Characters

Fig.3. Morphology of the mesothoracic furca in representatives of Ensifera (A, B, D–F) and Caelifera (C and G). (A–C) Volume rendering of mesothorax showing ventral longitudinal muscles inserting at anterior process * or anterior edge of mesofurca. Mesofurca is enclosing the pleural arm from ventral side. (D–G) 3D reconstruction of mesofurcae. In contrast to ensiferan representatives,the mesofurca of the caeliferan Xya sp. (G) bears an anterior process *.The muscles Ivlm7 (M.profurca-mesofurcalis) and Ivlm9 (M.prospina-mesofurcalis) insert at anterior processus or homologous area. pla2 (mesothoracic pleural arm).
