“…Anatomically, it provides attachment points for extensor muscles (Maulik, 1929;Furth, 1980;Schmitt, 2004). Hypotheses about the mechanism of jumping in flea beetles were presented in the works of Barth (1954) and Ker (R. F. Ker, Some structural and mechanical properties of locust and beetle cuticle, PhD thesis, Oxford University, 1977), and summarized in Furth (1988). The studies of Furth (1982Furth ( , 1988 and Furth et al (1983) were focused on the intergeneric comparative morphology and the anatomy of the modified metafemoral extensor tendon (MET), the so-called 'metafemoral spring' or 'metafemoral apodeme'.…”
