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).
