Japanocorus caeruleipennis, a striking species known from Japan and recently discovered by Kirill V. Makarov in Kunashir (Russian Far East), has been described as Toxotus caeruleipennis by Henry Walter Bates in 1873 [▽]. Mikhail Danilevsky estabilished for this taxon a new monotypic genus Japanocorus in 2012 [✧]. Larvae develop in soil on the roots of Cornus controversa, Cornus macrophylla and Benthamidia japonica. The adults are active from May to August [❖].
