Comments. The genus Distoleon is a large genus, comprising at least 120 species distributed all across the Old World ( Stange 2004). However, the larval stages are known only for the European D. tetragrammicus (Fabricius, 1798) (see below) and D. annulatus (Klug, 1834) ( Acevedo et al. 2013) and for few Asiatic species ( Stange et al. 2003; Stange 2004).
