Isodemis is a genus of moths belonging to the subfamily Tortricinae of the family Tortricidae.[1]

The genus was erected by Diakonoff in 1952 for the type species Batodes serpentinana. Diakonoff (1976, 1983) transferred Tortrix illiberalis to Isodemis and described Isodemis stenotera from Sumatra. Razowski (2000, 2009) described Isodemis proxima from Taiwan, and Isodemis brevicera, Isodemis longicera and Isodemis ngoclinha from Vietnam. Currently, Isodemis consists[2] of twelve species, mainly distributed in South-east Asia.

The forewing is dominantly yellowish brown or ochreous brown, the median fascia is interrupted or indistinct near the costal margin. The male genitalia have a hooked gnathos and the valva have a C-shaped plica, with numerous fine wrinkles between the plica and costa. The female genitalia usually have a ductus bursae with a cestum and the single dentate signum with a conspicuous globular process placed posteriorly in the corpus bursae.
