Velinoides dilatatus Matsumura, 1913: 161; Coranus magnus Hsiao & Ren, 1981: 514.
Distribution in Iran. Mazandaran (Sakenin et al. 2008).
Distribution outside Iran. China, Russia (East Siberia, Far East), Japan, Korea, Mongolia.
Comments. This is the largest Coranus species (body length about 18 mm) and can be easily recognized. Because the main distribution of C. dilatatus is in the east and northeast of Asia, the presence of this species in Iran needs confirmation. Of course, Mazandaran province is located south of Caspian Sea, contains a lot of various agricultural and forest ecosystems, and consequently a diverse insect fauna is expected; so the presence of rare taxa like C. (Velinoides) dilatatus in this area is not unexpected.
