Introduction '''''Isodemis''''' is a genus of moths belonging to the subfamily Tortricinae of the family Tortricidae.The genus was erected by Alexey Diakonoff in 1952 for the type species ''Batodes serpentinana''. Diakonoff (1976, 1983) transferred ''Tortrix illiberalis'' to ''Isodemis'' and described ''Isodemis stenotera'' from Sumatra. Józef Razowski (2000, 2009) described ''Isodemis proxima'' from Taiwan, and ''Isodemis brevicera'', ''Isodemis longicera'' and ''Isodemis ngoclinha'' from Vietnam. Currently, ''Isodemis'' consists of twelve species, mainly distributed in South-east Asia.
