Genus Helicopsyche Siebold

Only one named species Helicopsyche yamadai Iwata described based on the larval stage is known from Japan. Although it is necessary to confirm whether all specimens recorded from Honshu belong to a single species (Tanida 2005), unidentified adults recorded from Honshu is tentatively listed under the name of Helicopsyche yamadai. Shimura (2015) recorded larvae belonging to this genus from Fukue-jima.
